| 摘 要： | 采用氨基-葡聚糖（AD）保护的金颗粒作为灵敏的光学探针来检测外源凝集索伴刀豆球蛋白A（ConA）是一种正在发展中的检测方法．AD保护的金颗粒通过采用氨基-葡聚糖直接还原的方法制备，氨基-葡聚糖既为还原剂又是保护剂，金纳米颗粒的尺寸可以通过改变AD用量来调节．在中性环境下，AD与ConA以4：1的比率结合形成Au-ConA复合物，并且ConA引起颗粒的聚集．

| Abstract: | A sensitive method for the detection of thelectin protein concanavalin A(Con A)was developed using amino-dextran(AD)-protected gold(AD-Au)as sensitive optical probes.The AD-Au were synthesized by directly applying amino-dextran as a reductive and protective reagent.The size of the nanoparticles could bealtered by changing the molar ratio of AD to the metal salt.salt.The amino-dextran bound to Con A by forming a 4:1 Au-Con A complex at neutral pH,and the nanoparticles were induced to aggregate by Con A. |
