Microalgae present a novel and multifaceted approach to cancer therapy by modulating the tumor-associated microbiome (TAM) and the tumor microenvironment (TME). Through their ability to restore gut microbiota balance, reduce inflammation, and enhance immune responses, microalgae contribute to improved cancer treatment outcomes. As photosynthetic microorganisms, microalgae exhibit inherent anti-tumor, antioxidant, and immune-regulating properties, making them valuable in photodynamic therapy (PDT) and tumor imaging due to their capacity to generate reactive oxygen species (ROS). Additionally, microalgae serve as effective drug delivery vehicles, leveraging their biocompatibility and unique structural properties to target the TME more precisely. Microalgae-based microrobots further expand their therapeutic potential by autonomously navigating complex biological environments, offering a promising future for precision-targeted cancer treatments. We position microalgae as a multifunctional agent capable of modulating TAM, offering novel strategies to enhance TME and improve the efficacy of cancer therapies.

Three-dimensional (3D) printing, also referred to as additive manufacturing, is considered to be a game-changing technology in many industries and is also considered to have potential use cases in pharmaceutical manufacturing, especially if individualization is desired. In this review article the authors systematically researched literature published during the last 5 years (2019 – spring 2024) on the topic of 3D printed dosage forms. Besides all kinds of oral dosage forms ranging from tablets and capsules to films, pellets, etc., numerous reports were also identified on parenteral and cutaneous dosage forms and also rectal, vaginal, dental, intravesical, and ophthalmic preparations. In total, more than 500 publications were identified and grouped according to the site of administration, and an overview of the manuscripts is presented here. Furthermore, selected publications are described and discussed in more detail. The review highlights the very different approaches that are currently used in order to develop 3D printed dosage forms but also addresses remaining challenges.

The design of neural tissue models with architectural and biochemical relevance to native tissues opens the way for the fundamental study and development of therapies for many disorders with limited treatment options. Here, we systematically review the most recent literature on 3D bioprinted neural models, including their potential for use in drug screening. Neural tissues that model the central nervous system (CNS) from the relevant literature are reviewed with comprehensive summaries of each study, and discussion of the model types, bioinks and additives, cell types used, bioprinted construct shapes and culture time, and the characterization methods used. In this review, we accentuate the lack of standardization among characterization methods to analyze the functionality (including chemical, metabolic and other pathways) and mechanical relevance of the 3D bioprinted constructs, and discuss this as a critical area for future exploration. These gaps must be addressed for this technology to be applied for effective drug screening applications, despite its enormous potential for rapid and efficient drug screening. The future of biomimetic, 3D printed neural tissues is promising and evaluation of the in vivo relevance on multiple levels should be sought to adequately compare model performance and develop viable treatment options for neurodegenerative diseases, or other conditions that affect the CNS.

We report a new application of the recently developed technique, Optical Coherence Elastography (OCE) to quantitatively visualize kinetics of osmotic strains due to diffusive penetration of various osmotically active solutions into biological tissues. The magnitude of osmotic strains may range from fractions of one per cent to tens per cent. The visualized spatio-tempotal dynamics of the strains reflect the rates of osmotic dehydration and diffusional penetration of the active solute, which can be controlled by concentration of the solution components. Main features of the OCE-visualized diffusion-front dynamics well agree with Fick’s theory yielding diffusivity coefficients consistent with the literature data. The OCE technique may be used to study diffusion of a broad variety of osmotically-active substances − drugs, cosmetic agents, preservative solutions, so-called optical clearing agents enhancing the depth of optical visualization, etc. The corresponding experimental examples, some results of theoretical interpretations and numerical simulations are given.

Monitoring the kinetic changes of drugs and metabolites plays a crucial role in fundamental research, preclinical and clinical application. Raman spectroscopy (RS) is regarded as a fingerprinting technique that can reflect molecular structures but limited in applications due to poor sensitivity. Surface-enhanced Raman spectroscopy (SERS) significantly amplifies the detection sensitivity by plasmonic substrates, facilitating the identification and quantification of small molecules in biological samples, such as serum, urine, and living cells. This review will focus on advances in how SERS has been utilized to monitor the dynamic processes of small molecule drugs and metabolites in recent years. We first provide readers with a comprehensive overview of the mechanism and practical considerations of SERS, including enhancement theory, substrate design, sample pretreatment, molecule–substrate interactions and spectral analysis. Then we describe the latest advances in SERS for the detection and analysis of metabolites and drugs in cells, dynamic monitoring of drug in various biological matrices, and metabolic profiling for health assessment in biological fluids. We believe that high-performance SERS substrates, standardized technical regulations, and artificial intelligence spectral analysis will boost sensitive, accurate, reproducible, and universal molecular detection in the future. We hoped this review could inspire researchers working in related fields to better understand and utilize SERS for the analytical detection of drugs and metabolites.

Drug delivery via hair follicles has attracted much research attention due to its potential to serve for both local and systemic therapeutic purposes. Recent studies on topical application of various particulate formulations have demonstrated a great role of this delivery route for targeting numerous cell populations located in skin and transporting the encapsulated drug molecules to the bloodstream. Despite a great promise of follicle-targeting carriers, their clinical implementation is very rare, mostly because of their poorer characterization compared to conventional topical dosage forms, such as ointments and creams, which have a history spanning over a century. Gathering as complete information as possible on the intrafollicular penetration depth, storage, degradation/metabolization profiles of such carriers and the release kinetics of drugs they contain, as well as their impact on skin health would significantly contribute to understanding the pros and cons of each carrier type and facilitate the selection of the most suitable candidates for clinical trials. Optical imaging and spectroscopic techniques are extensively applied to study dermal penetration of drugs. Current paper provides the state-of-the-art overview of techniques, which are used in optical monitoring of follicular drug delivery, with a special focus on non-invasive in vivo methods. It discusses key features, advantages and limitations of their use, as well as provide expert perspectives on future directions in this field.

The microbiome, consisting of a wide range of both beneficial and harmful microorganisms, is vital to various physiological and pathological processes in the human body, including cancer pathogenesis. Tumor progression is often accompanied by the destruction of the vascular system, allowing bacteria to circulate into the tumor area and flourish in an immunosuppressive environment. Microbes are recognized as significant components of the tumor microenvironment. Recent research has increasingly focused on the role of intra-tumoral bacteria in the onset, progression, and treatment of breast cancer—the most prevalent cancer among women. This review elucidates the potential mechanisms by which intra-tumoral bacteria impact breast cancer and discusses different therapeutic approaches aimed at targeting these bacteria. It provides essential insights for enhancing existing treatment paradigms while paving the way for novel anticancer interventions. As our understanding of the microbiome’s intricate relationship with cancer deepens, it opens avenues for groundbreaking strategies that could redefine oncology.

In recent years, the field of 3D bioprinting has witnessed the intriguing development of a new type of bioink known as microbial inks. Bioinks, typically associated with mammalian cells, have been reimagined to involve microbes, enabling many new applications beyond tissue engineering and regenerative medicine. This review presents the latest advancements in microbial inks, including their definition, types, composition, salient characteristics, and biomedical applications. Herein, microbes are genetically engineered to produce 1) extrudable bioink and 2) life-like functionalities such as self-regeneration, self-healing, self-regulation, biosynthesis, biosensing, biosignaling, biosequestration, etc. We also discuss some of the promising applications of 3D extrusion printed microbial inks, such as 1) drugs and probiotics delivery, 2) metabolite production, 3) tissue engineering, 4) bioremediation, 5) biosensors and bioelectronics, 6) biominerals and biocomposites, and 7) infectious disease modeling. Finally, we describe some of the current challenges of microbial inks that needs to be addressed in the coming years, to make a greater impact in health science and technology and many other fields.

Cancer progression is significantly influenced by the complex interactions within the tumor microenvironment (TME). Immune cells, in particular, play a critical role by infiltrating tumors from the circulation and surrounding lymphoid tissues in an attempt to control their spread. However, they often fail in this task. Current in vivo and in vitro preclinical models struggle to fully capture these intricate interactions affecting our ability to understand immune evasion and predict drugs behaviour in the clinic. To address this challenge, biofabrication and particularly 3D bioprinting has emerged as a promising tool for modeling both tumors and the immune system. Its ability to incorporate multiple cell types into 3D matrices, enable tissue compartmentalization with high spatial accuracy, and integrate vasculature makes it a valuable approach. Nevertheless, limited research has focused on capturing the complex tumor-immune interplay in vitro. This review highlights the composition and significance of the TME, the architecture and function of lymphoid tissues, and innovative approaches to modeling their interactions in vitro, while proposing the concept of an extended TME.
