Several materials are recognized for their biocompatibility, including:
- Gold Nanoparticles: Known for their inertness and ease of functionalization. - Silica Nanoparticles: Biocompatible and versatile for various applications. - Polymeric Nanoparticles: Such as those made from poly(lactic-co-glycolic acid) (PLGA) which degrade into non-toxic byproducts. - Lipid-based Nanoparticles: Like liposomes, which are made from naturally occurring lipids.
