| 제목 | A SERS substrate of Chitosan-silver nanoparticle hybrid 3D structure for biomedicla application |
| 초록 | We propose a simple, low-cost, large-area, and functional surface enhanced Raman scattering (SERS) substrate for biomedical applications. The SERS substrate with chitosan-silver nanoparticles (chitosan-Ag NPs) hybrid 3D porous structure was fabricated simply by a one-step method. The chitosan was used as a template for the Ag NPs deposition. SERS enhancement by the chitosan-Ag NPs substrate was experimentally verified using rhodamine B as an analyte. Thiolated single stranded DNA was also measured for atopic dermatitis genetic markers (chemokines CCL17) at a low concentration of 5 pM. We successfully designed a novel SERS substrate with silver nanoparticle hybridized 3D porous chitosan that has the potential to become a highly sensitive and selective tool for biomedical applications. This research was supported by the Ministry of Trade, Industry and Energy(MOTIE), KOREA, through the Education Program for Creative and Industrial Convergence. (Grant Number N0000717)) |
