Drug delivery vehicle for therapeutic molecules

Drug delivery vehicles for therapeutic molecules represent a diverse category of engineered systems—including but not limited to liposomes, micelles, dendrimers, nanoparticles, polymeric carriers, and biological cells—designed to encapsulate, protect, transport, and release therapeutic agents in a controlled and targeted manner. These vehicles aim to address limitations of conventional drug administration, such as poor solubility, non-specific distribution, rapid degradation, and systemic toxicity. By exploiting properties like biocompatibility, surface modification, and stimuli-responsive mechanisms (e.g., responding to pH, temperature, or ultrasound), these systems can deliver drugs directly to disease sites, thereby enhancing efficacy and minimizing side effects. Applications are most pronounced in cancer therapy, but extend to infectious, inflammatory, and neurodegenerative diseases, among others. Safety challenges include toxicity of carrier materials, immune responses, variable biodistribution, and manufacturing consistency[1][2][3][4][5][6][7].
