Recent Development of Nanoparticle Platforms for Organophosphate Nerve Agent Detoxification

Poisoning by organophosphate (OP) nerve agents remains a pressing global threat due to their extensive use in chemical warfare agents and pesticides, potentially causing high morbidity and mortality worldwide. This urgent need for effective countermeasures has driven considerable interest in innovative detoxification approaches. Among these, nanoparticle technology stands out for its multifunctional potential and wide-ranging applications. This review highlights recent advancements in nanoparticle platforms developed for OP detoxification, focusing on five main types: inorganic nanoparticles, lipid-based nanoparticles, polymer-based nanoparticles, metal-organic framework nanoparticles, and cellular nanoparticles. For each platform, we discuss representative examples that illustrate how structural and functional properties enhance their effectiveness as nanocarriers, nanocatalysts, or nanoscavengers, ultimately enabling safe and efficient OP detoxification. This review aims to stimulate further technological innovation in OP-detoxifying nanoparticles and encourage broader development of detoxification strategies.
