Intracellular delivery is a research area focused on developing methods to efficiently transport molecules, such as drugs or genetic material, into the interior of cells. This field is important for improving the effectiveness of various therapeutic agents and understanding cellular processes. Intracellular delivery methods often involve specialized carriers, such as nanoparticles or liposomes, that can protect the cargo and facilitate its delivery into cells. Researchers are working to overcome barriers such as cell membrane permeability and endosomal escape in order to enhance the efficiency and specificity of intracellular delivery.
