Nanomedicine is an emerging field that utilizes nanoparticles to deliver drugs and other therapeutic agents to specific cells and tissues in the body. One of the most promising materials for creating these nanoparticles is Poly(Lactic-co-glycolic Acid) (PLGA), which has several unique properties that make it well-suited for biomedical applications. These nanomedicines, made from a combination of lactic acid and glycolic acid, can deliver drugs and other therapeutic agents directly to specific cells or tissues in the body. This allows for more precise and targeted treatment, reducing the potential for side effects and improving the effectiveness of the treatment. Additionally, PLGA nanomedicines are biocompatible and biodegradable, making them an attractive option for use in a wide range of biomedical applications to deliver a wide range of drugs, including proteins, peptides, nucleic acids, and small molecules for various biomedical applications such as neurodegenerative, cardiovascular diseases, inflammatory disorders, and cancer. In summary, research on PLGA nanoparticles for biomedical applications is ongoing and has the potential to lead a new and improved treatments for a wide range of diseases and conditions.

The development of new materials is ultimately associated with requirements such as strength, lightness, low production cost, and raw materials from renewable sources, seeking to meet the needs, research, and development of new technologies, which value the qualification of materials from vegetable sources as natural fibers. In this context, this study aimed to characterize the main physicochemical properties of the natural raffia fiber and its flammability and thermo-acoustic characteristics. These characterizations were performed using several techniques, such as chemical composition analysis, density, moisture adsorption, SEM-EDS, FTIR, and TGA/DTG. The results showed that the morphology of the raffia fiber presents a similar shape to the beehive. The Elemental analysis of the natural fiber of raffia shows that carbon and oxygen contents are predominant, representing a proportion of more than 90%. Furthermore, the results suggest that the fiber is composed of lignin, hemicellulose, cellulose, tannin, and extractives, with cellulose in a proportion of 80%. TGA presents a profile similar to large parts of untreated vegetable fibers. The acoustic test showed excellent sound absorption coefficient (α) values at high frequencies, while the flammability test showed that natural raffia fiber is a good flame retardant.

Nanotechnology augmentation have enabled the creation of innovative colloidal preparations that can modify the pharmacological characteristics of medications. Numerous effective applications in the treatment of cancer have been made possible by the distinctive physicochemical and technological characteristics of therapies based on nanomaterials. To facilitate and maximize the interaction between cells and tissues, it is necessary to examine and modify the size, shape, charge, and patterning of nanoscale therapeutic molecules. The flavonoids chalcones and their natural scaffolds provide a variety of biological effects crucial for creating medicines. Plant-based anticancer medicines represent a promising scientific and business opportunity that should be investigated. By using traditional Chinese medicine (TCM) therapies, diseases can be avoided, and healthcare can be enhanced. Traditional Chinese medicine is safe, straightforward, and reasonably priced. There are numerous treatments for chronic, geriatric, and incurable diseases. Heterocyclic equivalents of chalcones have a variety of biological properties. One of them is its anti-cancer properties, and as a result Chalcones have drawn a huge interest in the study of malignancy. Licorice is an essential primary ingredient in many traditional folk medicines, including Chinese and Mongolian medicine. Research on chalcone scaffolds with strong growth-inhibitory activity in tumor cell lines was influenced by the rising interest in this medicinal molecule, and numerous papers on these scaffolds are now accessible. It is necessary to do a thorough examination before chalcone congeners can be developed as a prodrug or primary chemical to treat cancer. To create a focused and efficient drug delivery system for cancer treatment, we shall discuss chalcone derivatives and their nano-enabled drug delivery systems in this article. It has been discussed how polymeric nanoparticles might effectively localize in particular tumor tissues and act as drug delivery vehicles for anticancer drugs due to their physicochemical characteristics. A promising strategy to increase the effectiveness of various tumor treatments is the nanoencapsulation of anticancer active substances in polymeric systems.

Natural rubber and epoxidized natural rubber composites reinforced with clay have been synthesized in this study using two roll mixing mill. The effect of clay concentration on basic mechanical properties and molecular transport phenomena of the elastomeric composites was analyzed. Tensile strength and tear strength variation as a function of clay concentration were studied. It was found that as clay concentration increased up to 4 phr, tensile strength improved up to 22.5MPa and tear strength up to 32 MPa, beyond which it went down. It was also found that corresponding to 4 phr clay concentrations, the crosslink density of the composite was at a maximum of 1.45gmol/cc. As the clay contents are added into the elastomeric matrix system, initially there is a decrease in the swelling coefficient, but later at higher loading, the swelling coefficient increases due to the agglomeration of clay particles in the matrix.

The oral route is the primary route for both acute and chronic treatment of epilepsy. However, lack of oral access during the seizures and high drug resistance limit the anti-epileptogenic effects of most antiepileptic drugs. Therefore, alternative routes and novel drug delivery systems are required. In this study, polymeric microneedles were formulated and characterized for possible intranasal administration of Tiagabine (TIA) in order to overcome the blood-brain barrier (BBB). In our study, carboxymethyl cellulose (CMC) and Eudragit® S 100 (ES100) based polymeric microneedles were formulated by micro-molding SEM, DSC, XRD, FT-IR, 1H-NMR, in vitro release, and texture analyses were performed. For the stability analyses, formulations were kept at 25 °C ± 2 °C (60 ± 5% Relative Humidity; RH), 40 °C ± 2 °C (75 ± 5% RH) and 5 °C ± 3 °C for six months. Analysis results revealed that robust microneedles were formulated successfully by micromolding method with adjustable needle lengths. Depending on the polymer type, sustained TIA releases up to 72 hours were achieved. Structural integrities were maintained at all storage conditions during the storage period of six months. TIA-loaded microneedles have the potential with less invasive properties, even with small amounts of TIA, through the unconventional nasal route for effective treatment of epilepsy.

Asparaginase (ASNase) is widely used as an important component of first-line treatment for acute lymphoblastic leukemia (ALL). Although it is associated with a high rate of complete remission (~93%), challenges remain due to several side effects ranging from immune reactions to severe toxicity, largely associated with its higher immunogenicity and glutamine coactivity. Innovative products have therefore been devised to minimise these adverse reactions while increasing the enzymes’ pharmacokinetic properties, stability, and efficacy. This review focuses on commercially available formulations and others that remain in development, discussing the most recent strategies for preparing alternative formulations of the enzyme to be less immunogenic and have low glutaminase coactivity by using site-specific mutagenesis, PEGylation, and encapsulation techniques.

This review explains the importance of polysaccharide derivatives in removing heavy metals and dyes from contaminated materials. With rising urbanization and industrialization, the availability of heavy metals and dyes in the environment is increasing. Heavy metals can cause a variety of health problems in individuals and offer major environmental dangers. This paper uses diverse techniques to discuss the most recent improvements in metal ion and dye adsorption from wastewater. Various derivatives of natural polymers can be used as good adsorbents for removing heavy metals and dyes from industrial wastewater and treated water released into the environment, lowering the risk of human disease and environmental problems. According to literature reviews, removing heavy metal ions from industrial effluent benefits both people and the environment. Graft copolymers are the most effective heavy metal ion and dye removal adsorbents, and the majority of them obey the pseudo-first and pseudo-second-order models. Also, an overview of each grafted co-polymers of polysaccharides for the adsorption of metal ions and dyes is mentioned in this review.
