Drug delivery enhancement

Drug delivery enhancement" refers to a diverse set of approaches that improve the localization, uptake, controlled release, and therapeutic concentration of drugs at target sites within the body, thereby minimizing off-target effects and maximizing efficacy. These approaches are not a singular molecular entity, receptor, or protein, but encompass programmable protein logic circuits[1], cell-based delivery vehicles[2], nanocarriers[9], responsive stimuli-targeted systems[3], and physical enhancement modalities (such as ultrasound or chemical permeation enhancers[7]). Enhancement strategies can employ engineered carriers like nanoparticles or biological cells, leverage passive or active targeting principles, and are tailored to overcome biological barriers (e.g., blood-brain barrier[6], skin[7]) or pathological microenvironments—rather than being a target itself. If you need specific information about a mechanism, molecule, or protein relevant to drug delivery enhancement (e.g., a nanoparticle surface ligand, a cellular surface marker used for targeting, or a programmable protein system), please specify the molecular or cellular entity for targeted details.
