提出了一种基于生物矿化作用的荧光素酶发射波长合理调谐的新策略。在这项研究中,荧光素酶(Luc 8)被用作模板,在环境条件下直接合成近红外(NIR)发光的PbS量子点(QD),以形成Luc 8 −PbS纳米复合物。合成的PbS量子点在800 - 1050 nm范围内显示出光致发光,Luc 8酶在Luc 8-PbS复合物中保持活性。在加入底物腔肠素后,Luc 8产生的能量通过生物发光共振能量转移(BRET)非辐射地转移到PbS QD,并使复合物能够发射NIR光。这是第一个通过活性酶模板合成无机纳米材料来形成双功能生物无机杂化纳米结构的研究。
A new strategy based on biomineralization is presented to rationally tune the emission wavelength of luciferase. In this study luciferase (Luc8) was used as a template to direct the synthesis of near-infrared (NIR) light emitting PbS quantum dots (QDs) at ambient conditions to form a Luc8−PbS nanocomplex. The as-synthesized PbS QDs exhibited photoluminescence in the range of 800−1050 nm, and the Luc8 enzyme remained active within the Luc8−PbS complex. Upon the addition of the substrate coelenterazine, the energy produced by Luc8 was nonradiatively transferred to PbS QDs via bioluminescence resonance energy transfer (BRET) and enabled the complex to emit NIR light. This is the first study to form dual functional bioinorganic hybrid nanostructures via active enzyme-templated synthesis of inorganic nanomaterials.
