The Application of Inorganic Nanoparticles in Molecular Targeted Cancer Therapy: EGFR Targeting

Epidermal growth factor receptor (EGFR) is an anticancer drug target for a number of cancers, such as non-small cell lung cancer. However, unsatisfying treatment effects, terrible side-effects, and development of drug resistance are current insurmountable challenges of EGFR targeting treatments for cancers. With the advancement of nanotechnology, an increasing number of inorganic nanomaterials are applied in EGFR-mediated therapy to improve those limitations and further potentiate the efficacy of molecular targeted cancer therapy. Given their facile preparation, easy modification, and biosecurity, inorganic nanoparticles (iNPs) have been extensively explored in cancer treatments to date. This review presents an overview of the application of some typical metal nanoparticles and nonmetallic nanoparticles in EGFR-targeted therapy, then discusses and summarizes the relevant advantages. Moreover, we also highlight future perspectives regarding their remaining issues. We hope these discussions inspire future research on EGFR-targeted iNPs.

Multifunctional Nanotherapeutics with All-in-One Nanoentrapment of Drug/Gene/Inorganic Nanoparticle

It is challenging but imperative to merge together specific inorganic nanomaterials with macromolecular and small-molecule therapeutics into one nanoentity for all-in-one theranostic/remedy. We establish a versatile nanotechnology to nanoentrap magnetic nanoparticles, doxorubicin, and DNA, thus allowing the combination of magnetic targeting, magnetic resonance (MR) imaging, gene transport, and bioresponsive chemotherapy. We hope this nanotechnology can prompt the development of complex inorganic/organic nanosystems for various applications.
