Special Issue Information

Dear Colleagues,

Proteins are some of the most versatile and well-studied macromolecules that can be incorporated into cells and biomaterials for the engineering of biosensors with biomedical applications. Protein-based biosensors and biomaterials have gained special attentions as they offer new opportunities in the development of high-throughput screening platforms for drug discovery, laboratory and point-of-care diagnostics, and theranostic tools. Cell-based biosensors have been widely used in the selection of chemical compounds with new pharmaceutical formulations in protein targeting through high-throughput screening to generate lead drug candidates. Similarly, polymeric and lipid-based nanoparticles and nanovesicles have been developed as nanomedicine as well as biosensing tools for biomedical applications and the goal is to translate these therapies and tools into the clinics. We invite authors to submit original articles and review articles highlighting the latest advances in protein-based biosensors and biomaterials with high sensitivity and specificity as well as potential for miniaturization, mass production, and high-throughput applications.

Overcoming the blood–brain barrier (BBB) remains a significant hurdle in effective drug delivery to the brain. While the BBB serves as a crucial protective barrier, it poses challenges in delivering therapeutic agents to their intended targets within the brain parenchyma. To enhance drug delivery for the treatment of neurological diseases, several delivery technologies to circumvent the BBB have been developed in the last few years. Among them, nanoparticles (NPs) are one of the most versatile and promising tools. Here, we summarize the characteristics of NPs that facilitate BBB penetration, including their size, shape, chemical composition, surface charge, and importantly, their conjugation with various biological or synthetic molecules such as glucose, transferrin, insulin, polyethylene glycol, peptides, and aptamers. Additionally, we discuss the coating of NPs with surfactants. A comprehensive overview of the common in vitro and in vivo models of the BBB for NP penetration studies is also provided. The discussion extends to discussing BBB impairment under pathological conditions and leveraging BBB alterations under pathological conditions to enhance drug delivery. Emphasizing the need for future studies to uncover the inherent therapeutic properties of NPs, the review advocates for their role beyond delivery systems and calls for efforts translating NPs to the clinic as therapeutics. Overall, NPs stand out as a highly promising therapeutic strategy for precise BBB targeting and drug delivery in neurological disorders. Full article
