强调金微结构的制造证明了阴离子荧光团的水凝胶内的多光子光还原。我们试图促进金离子的光还原附近的激光脉冲的焦点，期望在金离子附近的荧光团的氧化的电子捐赠。阴离子FITC-葡聚糖的存在也抑制了非靶向区的自发还原，这归因于金离子和阴离子FITC-葡聚糖的配位。同时促进和抑制是有希望的制造致密的金属微结构在目标区域，同时保持水凝胶的透光性。(C)根据OSA开放获取出版协议的条款，2020年美国光学学会
The fabrication of accentuated gold microstructures is demonstrated by multi-photon photoreduction inside an anionic fluorophore-containing hydrogel. We attempted to facilitate gold-ion photoreduction near the focal point of laser pulses, expecting the donation of electrons by the oxidation of fluorophores in the vicinity of gold ions. The presence of anionic FITC-dextran also inhibited the spontaneous reduction in untargeted zones, which is attributed to the coordination of gold ions and the anionic FITC-dextran. Simultaneous facilitation and inhibition are promising for the fabrication of dense metal microstructures in the targeted zone while maintaining the hydrogel's light permeability.
