1基于空间可分辨光谱的番茄成熟度判别方法研究显示文摘对基于空间可分辨光谱的番茄成熟度分类判别方法进行了试验研究。首先根据番茄的内部颜色,将600个番茄分为6个不同成熟度(green,breaker,turning,pink,light red and red),然后用自行开发的多通道高光谱成像探头采集番茄的空间可分辨(SR)光谱,建立基于空间可分辨光谱的番茄成熟度偏最小二乘判别(PLSDA)模型和支持向量机判别(SVMDA)模型。结果显示,对于PLSDA模型,SR光谱15为最佳分类光谱,分类正确率达到81.3%;对于SVMDA模型,SR光谱10为最佳预测分类光谱,分类正确率为86.3%。对六个成熟度等级番茄的判别分类,SVMDA模型要明显优于PLSDA模型。此外,相对于较小的光源-检测器距离SR光谱,较大的光源-检测器距离SR光谱可以获得更好的判别效果,显示出空间可分辨光谱在果蔬品质检测方面的应用潜力。黄玉萍 Renfu Lu 戚超 陈坤杰 2018光谱学与光谱分析2018,38,7:9

3波长比和近红外光谱的番茄品质检测方法显示文摘番茄的可溶性固形物(SSC)、pH值和坚实度(Firmness)是决定番茄的口感及收获后品质的主要因素。提出一种基于波长比和近红外光谱的番茄SSC,pH和坚实度检测方法。首先用Vis/SWNIR便携式光谱仪(波长:400~1 100nm)和中波近红外便携式光谱仪(波长:900~1 683nm)在相互作用模式下,对6个不同成熟度的600个番茄样本进行光谱采集,对所采集的光谱用波长比法和波长比+自动缩放法进行预处理后,分别建立番茄SSC,pH和坚实度的预测模型,比较单一自动缩放、单一波长比、波长比+自动缩放及不做预处理四种方法的预测结果。结果显示,波长比法结合自动缩放预处理可有效提高可见/短波近红外光谱对SSC,pH和坚实度的预测精度(r_p=0.779,0.796和0.917);波长比法+自动缩放法可提高中波近红外光谱对SSC的预测效果(rp=0.818)。这说明波长比法在优化和处理番茄光谱信息方面具有一定的潜力。黄玉萍 Renfu Lu 戚超 陈坤杰 2018光谱学与光谱分析2018,38,8:3
4A facile "ship-in-a-bottle" approach to construct nanorattles based on upconverting lanthanide-doped fluorides显示文摘格格声结构由于唯一的 core@void@shell 体系结构和函数的集成是对 nanomaterials 的设计和申请的大兴趣的一个话题。此处,我们开发了一个新奇 ship-in-a-bottle 方法制作 upconverting (UC ) 由把做 lanthanide 的氟化物合并到空 mesoporous 的光 nanorattles 硅石。nanorattles 的尺寸和氟化物的充满的数量能很好被控制。另外,硅石壳的修正(与苯撑和胺组) 并且有效 UC 氟化物的变化(NaYF 4:Yb,Er, NaLuF 4:Yb,Er, NaGdF 4:Yb,Er 和 LiYF 4:Yb,Er) 乐意地被完成。产生 nanorattles 展出了一个高能力和反癌症药 doxorubicin (纪录影片) 的 pH 依赖的版本。而且,我们由从 UC 氟化物利用精力转移过程到纪录影片在 proof-of-concept 监视 UC 药版本采用了这些 nanorattles,因此作为有效癌症 theranostic 揭示 nanorattles 的大潜力代理人。Shan Lu Datao Tu Xingjun Li Renfu Li Xueyuan Chen 2016Nano Research2016,9,1:3
5Multiplexed intracellular detection based on dual-excitation/dualemission upconversion nanoprobes显示文摘Multiplexed intracellular detection is desirable in biomedical sciences for its higher eficiency and accuracy compared to the single-analyte detection.However,it is very challenging to construct nanoprobes that possess multiple fluorescent signals to recognize the different intracellular species synchronously.Herein,we proposed a novel dual-excitation/dual-emission upconversion strategy for multiplexed detection through the design of upconversion nanoparticles(UCNP)loaded with two dyes for sensitization and quenching of the upconversion luminescence(UCL),respectively.Based on the two independent energy transfer processes of near-infrared(NIR)dye IR845 to UCNP and UCNP to visible dye PAPS-Zn,CIO-and Zn2+were simultaneously detected with a limit of detection(LOD)of41.4 and 10.5 nM,respectively.By tilizing a purpose built 830/980 nm dual-laser confocal microscope,both intrinsic and exogenous CIO and Zn2+in live MCF-7 cells have been accurately quantified.Such dual-excitation/dual-emission ratiometric UCL detection mode enables not only monitoring multiple intracellular analytes but also eliminating the detection deviation caused by inhomogeneous probe distribution in cells.Through modulation of NIR dye and visible dye with other reactive groups,the nanoprobes can be extended to analyze various intraellular species,which provides a promising tool to study the biological activities in live cells and diagnose diseases.Jianxi Ke Shan Lu Zhuo Li Xiaoying Shang Xingjun Li Renfu Li Datao Tu Zhuo Chen Xueyuan Chen 2020Nano Research2020,13,7:2
