Design Principles of Theranostic Nanopagentles

Designing effective theranostic nanopancicles requires a delicate balancing act. Below are te core design principles that guidee the development of these complex systems.

Biocompatibility andBiodegradability

Any material introlute into the body must avoid triggering acute toxicity or chronic immunome responses. Ideally, the nanopactivle itself or it degradation products should be cleared by natural metabolic pathays. Biodegraddable polimes like poliy (lactic- co- glicolic acid) and lipid- based carriers are favored for their proven safety profiles in approvised injettable formulations. For inorganic core materials such gold or iron oxide, sure coatings (polyene, silicothyla, silica, dexelica) are essentiail male improwiste.
