Effects of irradiation with visible light on the process of self-assembly in an aqueous l-cysteine-silver solution (CSS) and hydrogels based on were investigated using a set of physico-chemical methods. It was found that the exposure to light of CSS and hydrogels based on l-cysteine and silver acetate colors them firstly into yellow and subsequently to brown, which is due to the plasmon resonance of free electrons at the surface of resulting silver nanoparticles (AgNPs). A mechanism involving participation of AgNPs was proposed for the self-assembly in CSS and hydrogel.
使用一系列物理化学方法研究了可见光照射对l-半胱氨酸-银水溶液（CSS）及基于该溶液的水凝胶自组装过程的影响。结果发现，CSS及基于l-半胱氨酸和醋酸银的水凝胶在光照下首先变为黄色，随后变为棕色，这是由于所得银纳米颗粒（AgNP）表面自由电子的等离子体共振所致。提出了一种涉及AgNP参与的CSS和水凝胶自组装机制。
