Pharmaceutical, chemical and biological agents containing a reversible disulfide linker are described. These agents can also be covalently bound or contained in delivery vehicles for delivering the agents to desired targets or areas. Also described are delivery vehicles which contain an agent having a reversible disulfide linker and to vehicles that are covalently linked to the agent containing a reversible disulfide linker. The modifications described herein can modify properties of the agents and vehicles, thereby providing desired solubility, stability, hydrophobicity and targeting while the reversibility of the linker can leave the agent to which it is attached free from residual chemical groups after being reduced.

their drug cargo. The new co-polymers, in which PEG and PLGA were linked by ‘anchiomeric effector’ dithiylethanoate esters, were synthesized by a combination of ring-opening polymerization and Michaeladdition reactions and employed to prepare NPs. Non redox-responsive nanoparticles (nRR-NPs) based on related PLGA-PEG copolymers were also prepared as comparators. Spherical NPs of around 120 nm diameter
