Although various phase transfer techniques have been used to make hydrophobic nanoparticles (NPs) water-soluble However, these techniques have been limited by inefficient surface modification strategy that often stable NPs in aqueous solutions Herein, we report the use of 3-aminophenylboronic acid (3-APBA) as a hydrophilic ligand for phase transfer of oleylamine (OA) capped Au NPs (OA@Au NPs) from non-hydrolytic system into aqueous solutions The 3-APBA capped Au NPs (3-APBA@Au NPs) was mainly characterized using different anal. techniques to substantiate the efficiency of the phase transfer procedure. In this simple procedure, 3-APBA mol. was simultaneously used as both phase transfer and targeting ligand for bacteria recognition in one step. In principle, while free electron pair of amin (:NH2) group of 3-APBA bind to surface of hydrophobic Au NPs for phase transfer, diol group can bind to glycan on the membrane of Staphylococcus aureus and Methicillin-resistant Staphylococcus aureus (MRSA) through proper cis-diol configuration. In addition, the resulting 3-APBA@Au NP can effectively catalyze the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) in the presence of sodium borohydride (NaBH4) in aqueous solution
Different reactions of this compound(Hydrogen tetrachloroaurate(III) trihydrate)Application of 16961-25-4 require different conditions, so the reaction conditions are very important.
