ABSTRACTThe synthesis of biocompatible noble metal nanoparticles dispersible in a wide range of biological media with control of polycrystalinity and nanogeometry, pH sensitivity and salt tolerance has been a challenging requirements. The role of 3-aminopropyltrimethoxysilane (3-APTMS) and organic reducing reagents for real time synthesis of amphilic noble metal nanoparticles meeting these requirements are demonstrated justifying the following; (1) 3-APTMS capped noble metal ions are converted into respective metal nanoparticles in the presence of one of organic reducing agents i.e., cyclohexanone, tetrahydrofuran hydroperoxide (THF-HPO), formaldehyde, acetaldehyde, acetone, t-buty dimethyl keotone, 3-Glycidoxy-propyltrimethoxysilane (3-GPTMS); (2) 3-APTMS acts as micelle, promotes the interaction of metal ions with organic reducing agent, precisely controls the size of metal nanoparticles, pH sensititvity and salt tolerance and also provides a suitable medium for nanoparticles suspension, (3) the use of suitable organic reagent precisely controls the polarity of as made noble metal nanoparticles allowing specific biological interactions, and (4) 3-APTMS significantly increases the stability and controls the pH sensitivity and salt tolerance of metal nanoparticles. The as synthesized nanomaterials show potential viability in biomedical applications from many angles i.e. (a) as potential bioelectrocatalyst, (b) selective interaction with active proteins and cellular components, and (c) peroxidase mimetic.
