Photochemical reaction induced by enzymes intercalated into layered semiconductors

本研究将酶生物催化剂插入到层状半导体构成的二维空间中，研究了一种新的光诱导杂化反应。层状半导体在适当ph的溶液中通过静电相互作用使酶分子层间化。紫外光照射得到的杂化体通过半导体的光吸收和随后的能量转移引起层间酶的活化。此外，紫外光强度和波长可以很容易地调节酶的活性。

In the present study, enzyme biocatalysts were intercalated into two-dimensional space composed of layered semiconductors, and a novel photo-induced enzymatic reaction of the hybrids was investigated. The layered semiconductors interstratified the enzyme molecules through electrostatic interaction in a solution with an appropriate pH. Ultraviolet light irradiation to the obtained hybrids caused activation of enzymes in the interlayer by photoabsorption of semiconductor and subsequent energy transfer. Moreover, the enzymatic activity could be easily adjusted by UV light intensity and wavelength.
