Abstract

The influence of the solution acidity on the interaction between bovine serum albumin (BSA) molecules and gold nanoparticles in solutions has been investigated by absorbance spectroscopy, fluorescence spectroscopy, and dynamic light scattering (DLS). The influence of pH on the processes of aggregation–disaggregation of gold nanoparticles with BSA and without it and on the denaturation of protein solution is demonstrated. It is also shown that BSA molecules can stabilize gold nanoparticles at acidic pH values of 2.0–4.0. The data obtained can be useful for physiologists studying the influence of nanoparticles on different biological media of the body.

介质酸度对水溶液中金纳米粒子和牛血清白蛋白相互作用影响的光学研究

摘要通过吸光度光谱法、荧光光谱法和动态光散射法（DLS）研究了溶液酸度对溶液中牛血清白蛋白（BSA）分子和金纳米粒子之间相互作用的影响。结果表明，pH 值对有 BSA 和无 BSA 的金纳米粒子的聚集-解聚过程以及蛋白质溶液的变性都有影响。研究还表明，在 pH 值为 2.0-4.0 的酸性环境中，BSA 分子可以稳定金纳米粒子。获得的数据对生理学家研究纳米粒子对人体不同生物介质的影响很有帮助。
