Abstract Blood–brain barrier (BBB) is a natural protective membrane that prevents central nervous system (CNS) from toxins and pathogens in blood. However, the presence of BBB complicates pharmacotherapy for CNS disorders as most chemical drugs biopharmaceuticals have been impeded to enter brain. Insufficient drug delivery into brain leads low therapeutic efficacy well aggravated side effects due accumulation other organs tissues. Recent breakthrough materials science nanotechnology provides library advanced with customized structure property serving powerful toolkit targeted delivery. In-depth research field anatomical pathological study on further facilitates development brain-targeted strategies enhanced crossing. In this review, physiological different cells contributing are summarized. Various emerging permeability regulation crossing including passive transcytosis, intranasal administration, ligands conjugation, coating, stimuli-triggered disruption, overcome obstacle highlighted. Versatile systems ranging organic, inorganic, biologics-derived their synthesis procedures unique physio-chemical properties summarized analyzed. This review aims provide an up-to-date comprehensive guideline researchers diverse fields, offering perspectives system.

Norepinephrine (NE) is synthesized in the locus coeruleus and widely projected throughout brain spinal cord. It regulates various actions consciousness linked to a variety of neurological diseases. A "hunting-shooting" strategy was proposed this work improve specificity response rate an NE fluorescent probe: 2-(cyclohex-2-en-1-ylidene)malononitrile derivatives were chosen as fluorophore. To create dual-site probe, aldehyde group added ortho ester (or benzene sulfonate). Because its excellent electrophilic activity, could rapidly "hunt" amino then form intramolecular five-membered ring via nucleophilic reaction with β-hydroxyl group. The -NH- "shoots" adjacent group, releasing fluorophore allowing for rapid specific detection. release reuptake ″emetic″-″swallow″ transient process captured visualized under action primary receptor drug. Furthermore, by introducing halogen into lengthen absorption wavelength, lipid solubility, adjust pKa appropriately, probe successfully penetrated blood-brain barrier (BBB).

In the human body, almost all cells interact with extracellular matrices (ECMs), which have tissue and organ-specific compositions architectures. These ECMs not only function as cellular scaffolds, providing structural support, but also play a crucial role in dynamically regulating various functions. This comprehensive review delves into examination of biofabrication strategies used to develop bioactive materials that accurately mimic one or more biophysical biochemical properties ECMs. We discuss potential integration these ECM-mimics range physiological pathological vitro models, enhancing our understanding behavior organization. Lastly, we propose future research directions for context engineering organ-on-a-chip applications, offering advancements therapeutic approaches improved patient outcomes.

Overcoming the blood–brain barrier (BBB) remains a significant hurdle in effective drug delivery to brain. While BBB serves as crucial protective barrier, it poses challenges delivering therapeutic agents their intended targets within brain parenchyma. To enhance for treatment of neurological diseases, several technologies circumvent have been developed last few years. Among them, nanoparticles (NPs) are one most versatile and promising tools. Here, we summarize characteristics NPs that facilitate penetration, including size, shape, chemical composition, surface charge, importantly, conjugation with various biological or synthetic molecules such glucose, transferrin, insulin, polyethylene glycol, peptides, aptamers. Additionally, discuss coating surfactants. A comprehensive overview common vitro vivo models NP penetration studies is also provided.
