제목 One-pot synthesis of a zwitterionic small molecule bearing disulfide moiety for anti-biofouling macro and nanoscale gold surfaces
초록 The goal of this study is to develop a one-pot synthesis of a zwitterionic small molecule which provides effective anti-biofouling properties on macroscopic and nanoscopic gold surfaces. To this end, a zwitterionic small molecule was successfully synthesized by utilizing dipyridyl disulfide in a one-pot method. The coating conditions and stablity were examined through contact angle measurements, surface plasmon resonance (SPR), and X-ray photoelectron spectroscopy. The anti-biofouling properties of the coated gold surface were analyzed by FITC-bovine serum albumin (BSA) test and SPR as contacting with BSA solution. In addition, the effect of zwitterion-coating on stability of and protein adsorption on gold nanoparticles were examined through a NaCl stability test and BSA adsorption test, respectively. As a result, simply synthesized zwitterionic small molecule effectively enhanced the anti-biofouling properties gold surfaces and the salt stability of gold nanoparticles.
