Description
General Description
PLGA-PEG-Folate is a targeted biodegradable copolymer designed for receptor-mediated drug delivery applications. The hydrophobic PLGA segment forms the core of nanoparticles and micelles capable of encapsulating hydrophobic drugs, proteins, peptides, nucleic acids, and imaging agents, while the PEG segment forms a hydrophilic corona that enhances colloidal stability, prolongs circulation time, and reduces nonspecific protein adsorption.
The folic acid ligand exhibits high affinity toward folate receptors, which are overexpressed on numerous cancer cells including ovarian, breast, lung, kidney, colorectal, and cervical cancers. This receptor-mediated uptake pathway promotes enhanced cellular internalization and targeted delivery of therapeutic agents.
PLGA-PEG-Folate is frequently employed in targeted nanoparticle development, cancer drug delivery, molecular imaging, diagnostic applications, and advanced nanomedicine research.
