Cancer is a significant global health issue, with rising prevalence and mortality rates demanding urgent attention. The World Health Organization emphasizes the need for effective prevention, early detection, and treatment strategies to address this public health challenge. Current treatment modalities, including surgery, hormonal therapy, immunotherapy, radiation therapy, and chemotherapy, are often associated with considerable side effects and high costs. This study investigates the biosynthesis of silver nanoparticles using Acalypha indica L. (AgNPs), a medicinal plant recognized for its therapeutic benefits, as a potential cancer treatment with minimal side effects and a lower risk of drug resistance. AgNPs exhibit anti-inflammatory properties and the ability to inhibit angiogenesis while counteracting drug resistance mechanisms. Moreover, the use of chitosan as a coating on AgNPs (AgNPs-Chit) enhances their stability and specificity toward cancer cells, thereby improving their anticancer efficacy. Characterization of the synthesized AgNPs was conducted using various techniques, including UV-Vis spectroscopy, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), particle size analysis (PSA), and transmission electron microscopy (TEM), confirming the successful synthesis, stability, and spherical morphology of the nanoparticles, with an average diameter of 7 nm and a zeta potential of −24.51 mV. In vitro cytotoxicity testing showed that AgNPs-Chit exhibited stronger anticancer activity against T47D cells with an IC50 value of 173 µg/mL, compared to AgNPs (IC50 244 µg/mL) and the Acalypha indica L extract (IC50 826 µg/mL). When compared to the control, treatments with AgNPs-Chit, AgNPs, and the plant extract demonstrated statistically significant differences (∗p < 0.05, ∗∗p < 0.01). These results indicate that the modification of AgNPs with chitosan (AgNPs-Chit) significantly enhances anticancer efficacy compared to both AgNPs and Acalypha indica L. extract. The modification with AgNPs increased anticancer efficiency by 338%, while AgNPs-Chit showed a 446% increase compared to the original extract, highlighting the enhanced potential of these nanoparticles in inhibiting cancer cell growth. Additionally, molecular docking studies of eight key compounds identified through LC-MS analysis (quercetin, kaempferol, catechin, indoline, 4-aminobenzoic acid, 1-(2-quinolinyl)piperazine, 3-indoleacrylic acid, and pyridine-3-carboxamide) revealed strong binding affinities to the cancer target protein 3PP0, with binding energies ranging from −9.4 to −5.9 kcal/mol, compared to doxorubicin's binding energy of −9.0 kcal/mol.

Human papillomavirus subtypes 16 and 18-associated cervical cancer is a major global health problem that affects women.
Main body
Conventional treatment approaches, including chemotherapy, immunotherapy, and gene therapy, are typically vulnerable to systemic harm, cytotoxicity, non-specificity, lack of bioavailability, poor efficacy, poor pharmacokinetics, vaginal mucosal impermeability, slow therapeutic delivery, and adverse reactions. Moreover, conventional therapeutic approaches have problems associated with biocompatibility, stability, dispersion, and the delivery of therapeutic genes into target cells. They also produce modest amounts of long-lasting antitumor immunity and have difficulty successfully targeting and eliminating cancer cells. For this reason, nanoparticles, including polymers like poly-amidoamine and polylactide-co-glycolide dendrimers, aptamers, micelles, lipid-based nanocarriers like liposomes and pegylated lipoplexes, macromolecules, and metallic nanoparticles, including silica, copper oxide, zinc oxide, iron oxide, gold, and silver, are of paramount importance to overcome the numerous drawbacks of carrying and transporting diverse types of HPV-16 and 18-caused cervical cancer therapeutic agents. This review summarizes the application of nanoscale materials to deliver various therapeutic agents to cervical cancer cells.
Conclusions
The use of nanoparticles as medical nanoscale materials during the treatment of cervical cancer helps to improve the efficacy of various therapeutic modalities, speed up the delivery process, and decrease toxicity from drugs.

Bilastine, a second-generation antihistamine, is commonly prescribed for managing allergic rhinoconjunctivitis and urticaria due to its prolonged action. However, its therapeutic potential is constrained by poor water solubility and low oral bioavailability. This study aimed to enhance bilastine dissolution and patient compliance by formulating a nanosuspension-based orodispersible film (ODF). An anti-solvent precipitation method was employed to produce nanosuspension using different hydrophilic stabilizers (Soluplus®, Poloxamer 188, and PEG 6000). The influence of formulation parameters, such as the stabilizer ratio, the anti-solvent ratio, stirring speed, and the stabilizer type, on particle size and polydispersity index (PDI) was optimized using an experimental design approach. The optimal formulation, with a 1:1 stabilizer-to-drug ratio using Soluplus®, a 6:1 anti-solvent to solvent ratio, and a stirring rate of 820 rpm, yielded nanoparticles with a mean particle size of 83.8 nm and a narrow PDI of 0.019. This formulation also significantly enhanced the drug's dissolution rate in phosphate buffer pH 6.8, releasing 92.02% of bilastine within 90 minutes. Further characterization of the lyophilized nanoparticles using FESEM, FTIR, and XRD, confirmed their amorphous nature and drug compatibility. The optimized nanosuspension was subsequently incorporated into ODFs via the solvent-casting technique, with the optimal film formulated with a 1:1 ratio of PVA and HPMC E5 as the film-forming polymers, demonstrating a rapid disintegration time of 18 seconds and releasing 93.16% of bilastine within 6 minutes. These results confirm the successful formulation of bilastine into ODFs, significantly improving its dissolution compared to the pure drug.

This study explores a comparative analysis of PLGA nanoparticles and liposomes as potential carriers for brain cancer drug delivery, with a special focus on how material informatics enhances their design, biocompatibility, and drug release profiles to improve treatment efficacy and contribute to sustainable health outcomes.
The investigation employed a bibliometric analysis using Scopus and VOSviewer to uncover the role of material informatics in optimizing these nanocarriers. The analysis revealed that material informatics, particularly through the application of machine learning and molecular dynamics simulations, significantly optimizes the performance of both PLGA nanoparticles and liposomes.
The results highlighted distinct strengths of each nanocarrier: PLGA nanoparticles excel in biodegradability, while liposomes offer superior drug encapsulation capabilities. However, material informatics techniques bridged these enhancing drug release kinetics, stability, and biocompatibility. These improvements are crucial for effective delivery across the blood-brain barrier, a major challenge in brain cancer treatment.
The integration of computational modelling, machine learning, and high-throughput screening enabled by material informatics is shown to be a key factor in advancing the design and optimization of these nanocarriers. By leveraging these tools, researchers can develop more personalized and efficient drug delivery systems tailored to address the specific challenges of glioblastoma therapy, ultimately contributing to sustainable health outcomes

MRI is a powerful, non-invasive imaging technique with exceptional soft tissue contrast, requiring contrast agents to enhance sensitivity by shortening longitudinal (T1) and transverse (T2) relaxation times. While most clinical agents are chelate-based, their potential toxicity has driven the development of nanoparticle-based alternatives. Nanoparticles offer reduced toxicity, improved stability, prolonged circulation time, and better control over surface properties. Lanthanide-based nanoparticles, in particular, are promising due to their paramagnetic properties enhancing MRI contrast. The design of these nanoparticles focuses on optimizing size, shape, and colloidal stability with advances in synthesis techniques allowing for precise control over particle size, morphology, and stability to significantly influence relaxivity. Larger sizes increase r₂ values but may reduce stability, while anisotropic shapes enhance relaxivity compared to the more stable spheres. Surface modifications with functional polymers improve stability and prevent aggregation, optimizing imaging performance. As research progresses, lanthanide-based nanoparticles are poised to become crucial tools in radiology-driven cancer diagnosis and therapy, offering dual functionality for early detection, targeted treatment, and minimized off-target effects. However, these nanoparticles must be refined for tumour-specific diagnostic and therapeutic applications and undergo comprehensive safety evaluations before clinical trials.

There is a pressing need for new cell-laden, printable bioinks to mimic stiffer tissues such as cartilage, fibrotic tissue and bone. PEGDA monomers are bioinks that crosslink with light to form a viscoelastic solid, however, they lack cell adhesion properties. Here, we utilized a hybrid bioink by combining self-assembled peptide nanofibers with PEGDA for 3D printing lumens. Adult human dermal fibroblast (aHDF) cells were first seeded in peptide-laden in 2D and 3D layers and cell behavior were studied. The cell's morphology remained spheres when they were infused in the 3D hydrogel and highly aligned with 2D overlay hydrogels. HDF cells did not adhere to unmodified PEGDA lumens, however, they successfully attached and proliferated on PEGDA/peptide lumens. Moreover, HDF cells seeded on the hybrid PEGDA/peptide lumens displayed a distinct spread F-actin morphology. The results showcase the potential of peptide hydrogels in facilitating interaction of anchorage dependent cells with PEGDA structures.

The biosynthesis of silver nanoparticles from ginger extract is particularly interesting due to the bioactive compounds present in ginger, which have antioxidant, antimicrobial, and anti-inflammatory properties. The study aims to optimize, characterize, and evaluate the toxicity value of the biosynthesized silver nanoparticles using Bentong ginger (Zingiber officinale) rhizome extract and commercialized ginger powder extract as reducing and capping agents. The synthesis was optimized regarding pH, silver nitrate concentration, and incubation time for better yield and stability. Additionally, biosynthesized silver nanoparticles were characterized using UV–vis spectrophotometer, X-ray diffraction, Fourier-transform Infrared, and Transmission Electron Microscope analysis. Cytotoxicity test was done using brine shrimp lethality test to determine toxicity value. The result for both Bentong ginger rhizome extract and commercialized ginger powder extract indicated that the maximum absorption of biosynthesized silver nanoparticles was 450 nm, with the most optimum pH of 11, 1 mM of silver nitrate concentration, and incubation time of 24 h. The nanoparticles were almost spherical, with an average particle size of 15.08 ± 6 nm. The analysis confirms the presence of phytochemicals in the ginger extract that aids in reducing silver ions into silver nanoparticles. Brine shrimp lethality assay showed the LC50 for AgNPs was medium toxic at 838.31 µg/mL. Although silver nanoparticles possess antimicrobial ability, the potential toxicity to human health and environmental concerns must be considered before deploying into food industries. This is the first report utilizing Bentong ginger in silver nanoparticle synthesis.

The continuous increase of bacterial resistance in medical and industrial environments is a significant challenge due to their resistance to typical antimicrobial treatments. This study aimed to introduce a new colloidal solution containing chitosan/thyme oil/MgO Bionanocomposite with the strongest antibacterial activity. In situ synthesis method was used for the synthesis of the chitosan/thyme oil/MgO nanocomposite. Nine experiments based on the Taguchi design were created to examine the effects of three variables at three different levels. In the parameters of experiment 7 (3 mg/mL of chitosan Biopolymer, 0.5 μL/mL of thyme oil, and 6 mg/mL of MgO), the results showed that the bacterial viability was zero. The nanocomposite demonstrated enhanced structural properties and superior antibacterial activity compared to its individual components. This study showed that the synthesized nanocomposite had desirable structural properties and antibacterial activity under optimal conditions.

Small interfering RNA (siRNA) is essential for the process of gene silencing, especially for cancer. Despite its considerable promise, siRNA faces challenges due to stability issues of formulation and undesirable off-target side effects. In order to address these difficulties, it is essential to carefully monitor the levels of siRNA. The existing point-of-care (POC) systems cannot precisely and efficiently detect or monitor siRNA levels. In light of these challenges, this review gives the prospects of siRNA detection by proposing a novel hypothesis of existing electrical and optical-based detection of DNA/RNA with the POC platform. This hypothesis offers an interesting novel perspective to potentially fill the existing gaps, in detecting siRNA. By utilising these technologies, there is high potential to develop a proof-of-concept system that will not only overcome the existing challenges, but it will also allow effective and precise monitoring of siRNA, in real-world healthcare environments. In summary, the prospects for siRNA in the realm of POC platforms are quite encouraging, since it allows precise and effective monitoring.

Green technologies have gained prominence, particularly in the environmentally friendly synthesis of compounds, with Selenium nanoparticles (SeNPs) emerging as a key area of interest due to their potential in drug development. The sustainable production of SeNPs using microorganisms and plants enhances their physical, chemical, and biological properties, improving their catalytic efficiency. Recent advancements in nanotechnology, especially in medicine and antimicrobial research, highlight the growing significance of green synthesis methods. These eco-conscious approaches aim to preserve natural resources while promoting sustainable nanoparticle production techniques. This review focuses on SeNPs' antimicrobial action as well as the factors that influence their green production, such as pH, temperature, and precursor concentration, all of which affect their morphology, size, and stability. SeNPs' antimicrobial activity against a diverse range of bacteria, fungi, and viruses is extensively tested, with a focus on their capacity to battle drug-resistant infections and biofilms. The mechanisms of SeNPs' antimicrobial effect are investigated, including membrane disruption, reactive oxygen species (ROS) production, and interactions with cellular components. Furthermore, their antiviral characteristics and ability to alter immune responses highlight their medicinal applications. SeNPs represent a significant advancement in green nanotechnology, offering sustainable solutions to pressing biomedical challenges, particularly in the fight against drug-resistant pathogens.
