中文摘要 | 利用檸檬酸鈉還原Au(Ⅲ)離子合成產生的金奈米粒子能和修飾雙硫鍵結的DNA產生共價鍵結。修飾互補DNA的兩種金奈米粒子能藉由DNA的雜交反應產生自組排列現象。這種反應會使金奈米粒子溶液由紅色變為藍色。這個結果顯示具有DNA修飾的金奈米粒子運用在生物感測和DNA探針應用於疾病診斷的潛力。 |
英文摘要 | Gold nanoparticles were synthesized by reducing HAuCl4 with trisodium citrate. These gold nanoparticles could react with disulfide group modified DNAs well. The DNAs modified gold nanoparticles assembled into regular array according to the hybridization of two complementary DNAs linked on gold nanoparticles individually. This reaction caused the color of gold nanoparticle solution changed from red to blue. Thus, this phenomenon showed the potential of DNAs modified gold nanoparticles to be applied in biosensing or as DNA probes for diagnosis. |
