Abstract

The bactericidal properties of chemically patterned lithium niobate substrates under a super-bandgap UV light source is established. UV irradiation of lithium niobate surfaces inoculated with bacteria leads to antimicrobial activity compared to a glass substrate under similar conditions, as determined by surface enhanced Raman spectroscopy and corroborated with a fluorescence-based live/dead assay. This finding may expand the possible biomedical applications of lithium niobate.

铌酸锂晶体基材的抗菌性能

摘要

建立了超带隙紫外光源下化学图案化铌酸锂基材的杀菌特性。与相似条件下的玻璃基材相比，接种细菌的铌酸锂表面的紫外线照射可产生抗菌活性，这一点通过表面增强拉曼光谱确定，并通过基于荧光的活/死测定法证实。这一发现可能会扩大铌酸锂可能的生物医学应用。
