Self-adjusting omniphilic nanocarriers (OPNs) with a multisolvent aptitude were prepared via a Schiff base reaction between chitosan, a natural polysaccharide, and bioactive aldehydes. Experimental studies supported by atomistic molecular dynamics simulations revealed these OPNs can encapsulate insoluble molecular cargo, transport them in aqueous or lipid environments, and deliver them through cross-phase barriers. N-imine dynamic covalent bonds have been incorporated to endow the OPNs with pH responsiveness, also allowing the amplification of their bioactivity, as demonstrated in vitro with the ability to delay fungal proliferation in wheat grains. The reported OPNs hold remarkable potential as biocompatible nanocarriers for the effective delivery of active agents in agriculture, medicine, and cosmetics.
