不同物种衍生的鸟嘌呤微晶具有磁性可控的光学性质，具有广阔的应用前景。虽然类似的晶体还没有被遗传制造，但通过化学过程生产的鸟嘌呤晶体是商业上可获得的。在这项研究中，我们研究了磁响应和光反射性能的合成和生物鸟嘌呤晶体在几百毫特斯拉（mT）的实时显微镜和光谱测量。结果表明，合成晶体显示可控的光操纵性能与生物晶体相比，因此也可能找到可能的应用作为微镜在光学仪器和MEMS。
The magnetically controllable optical properties of guanine micro crystals derived from various species with camouflaging abilities offer promising prospects for future applications. Whereas comparable crystals have yet to be manufactured genetically, guanine crystals produced by chemical process are commercially available. In this study we examined the magnetic response and light reflecting properties of synthetic and biogenic guanine crystals under several hundred millitesla (mT) by means of real-time microscopy and spectroscopic measurement. Results show that synthetic crystals display controllable light manipulating properties comparable to those seen with biogenic crystals, and thus may also find possible application as micro-mirrors in optical instruments and MEMS.
