Potential utilization of proteins for early d.tection and.d.agnosis of various d.seases has d.awn consid.rable interest in the d.velopment of protein-based.d.tection techniques. Metal ind.ced.fluorescence enhancement offers the possibility of increasing the sensitivity of protein d.tection in clinical applications. We report the use of tunable plasmonic silver nanostructures for the fluorescence enhancement of a near-infrared.（NIR） d.e （Alexa Fluor 790）. Extensive fluorescence enhan- cement of -2 ord.rs of magnitud. is obtained.by the nanoscale control of the Ag nanostructure d.mensions and.interparticle d.stance. These Ag nanostructures also enhanced.fluorescence from a d.e with very high quantum yield.（7.8 fold.for Alexa Fluor 488, quantum efficiency （Qy） = 0.92）. A combination of greatly enhanced.excitation and.an increased.rad.ative d.cay rate, lead.ng to an associated.enhancement of the quantum efficiency lead. to the large enhancement. These results show the potential of Ag nanostructures as metal ind.ced.fluorescence enhancement （MIFE） substrates for d.es in the NIR ＂biological wind.w＂ as well as the visible region. Ag nanostructured.arrays fabricated.by colloid.l lithography thus show great potential for NIR d.e-based.biosensing applications.

针对结合星地观测与模型定量模拟消光性气溶胶光学特性及黑碳质量空间分布这一热点问题,利用TROPOMI卫星紫外波段观测数据与AERONET地基观测数据,基于“核-壳”假设下的米散射模型提出了一种准确量化黑碳气溶胶质量空间分布的模拟方法,并对北京、中国香港、首尔三个站点的模拟结果进行分析与验证。多源数据约束后米散射模型模拟得到的结果显示:北京的吸收系数在0.04~0.13之间,中国香港的吸收系数整体小于0.08,首尔的吸收系数介于0.02~0.06之间。计算得到的黑碳气溶胶柱内质量空间分布结果显示:北京站黑碳气溶胶柱内质量在200~600 kg/grid.间,中国香港站黑碳气溶胶柱内质量在180~650 kg/grid.间,首尔站黑碳气溶胶柱内质量在300 kg/grid.下。结合卡尔曼滤波排放清单与一阶箱模型对黑碳气溶胶柱内质量结果进行间接验证,计算得到的黑碳气溶胶生命周期为1~4 d.等,符合其在大气中的真实状态,说明结果具有一定可靠性。通过对比加入TROPOMI紫外波段卫星观测数据前后对模型进行约束得到的粒径分布及吸收系数结果的差异发现:加入紫外波段观测数据对模拟结果具有一定增强作用。所提方法模拟结果良好,方案具有一定应用潜力。
