Detection of E. coli in beach water within 1 hour using immunomagnetic separation and ATP bioluminescence
Luminescence - Tập 19 Số 1 - Trang 31-36 - 2004
Ji‐Young Lee, Rolf A. Deininger
AbstractThe contamination of beach waters occurs from the discharge of storm water and sanitary sewer overflows containing faecal material. Additional faecal material derives from discharge of animals and waterfowl. In order to protect public from exposure to faecal‐contaminated water, it is required to test enteric indicators in beach water. The problem is that the...... hiện toàn bộ
Photoluminescence properties of a novel phosphor CaB2O4:Eu3+ under NUV excitation
Luminescence - Tập 24 Số 6 - Trang 363-366 - 2009
Junli Huang, Liya Zhou, Qi Pang, Fuzhong Gong, Jianhua Sun, Wei Wang
AbstractThe new borate phosphor CaB2O4:Eu3+ was synthesized by solid‐state method and their photoluminescence properties were investigated. The results show that the pure phase of CaB2O4 could be available at 900°C, CaB2O4... hiện toàn bộ
A new fluorescent chemosensor for cadmium(II) based on a pyrene‐appended piperidone derivative and its β‐cyclodextrin complex
Luminescence - Tập 33 Số 3 - Trang 538-544 - 2018
Sumathi Poomalai, Tamil Selvan Govindaraj, Soundrapandian Suganthi, Mosae Selvakumar Paulraj, Israel V.M.V. Enoch
AbstractWe report, in this article, a piperidin‐4‐one derivative carrying pyrenyl fluorescent reporter groups which acts as a Cd2+ ion sensor. The compound is synthesized and characterized using IR and NMR spectral techniques. The compound forms an inclusion complex with β‐cyclodextrin. It selectively binds to Cd2+ ions in ...... hiện toàn bộ
Construction of photodynamic‐effect immunofluorescence probes by a complex of quantum dots, immunoglobulin G and chlorin e6 and their application in HepG2 cell killing
Luminescence - Tập 31 Số 6 - Trang 1174-1181 - 2016
Zhengyu Yan, Lili Wang, Meng‐Ying Fei, Xinying Liu, Yilong Su, Qingqing Du, Sheng‐Mei Wu
AbstractIn this study, tri‐functional immunofluorescent probes (Ce6–IgG–QDs) based on covalent combinations of quantum dots (QDs), immunoglobulin G (IgG) and chlorin e6 (Ce6) were developed and their photodynamic ability to induce the death of cancer cells was demonstrated. Strategically, one type of second‐generation photosensitizer, Ce6, was first coupled with an...... hiện toàn bộ
Simple synthesis of luminescent CdSe quantum dots from ascorbic acid and selenium dioxide
Luminescence - Tập 30 Số 8 - Trang 1375-1379 - 2015
Yilin Wang, Meihua Yu, Kun Yang, Jianping Lu, Linqing Chen
AbstractA simple, low‐cost and convenient method was developed for the synthesis of highly luminescent CdSe quantum dots (QDs) in an aqueous medium. Compared with previous methods, this synthesis was carried out in one pot using ascorbic acid (C6H8O6) to replace NaBH4 or N...... hiện toàn bộ
Luminescent gelatin nanospheres by encapsulating CdSe quantum dots
Luminescence - Tập 29 Số 1 - Trang 74-78 - 2014
Longyan Chen, Adrienne Willoughby, Jin Zhang
ABSTRACTQuantum dots (QDs) have been encapsulated within gelatin nanoparticles (GNPs), which gives GNPs fluorescent properties and improves the biocompatibility of QDs. Hydrophilic CdSe QDs were produced through thermodecomposition following the ligand‐exchange method, and were then encapsulated in GNPs. The results of high‐resolution transmission electron microsco...... hiện toàn bộ
Microwave‐assisted aqueous synthesis of new quaternary‐alloyed CdSeTeS quantum dots; and their bioapplications in targeted imaging of cancer cells
Luminescence - Tập 28 Số 3 - Trang 392-400 - 2013
Fengzhao Yang, Zhancheng Xu, Jinjie Wang, Zan Feng, Chaoqing Dong, Jicun Ren
ABSTRACTIn this study, we report for the first time a one‐pot approach for the synthesis of new CdSeTeS quaternary‐alloyed quantum dots (QDs) in aqueous phase by microwave irradiation. CdCl2 was used as a Cd precursor during synthesis, NaHTe and NaHSe were used as Te and Se precursors and mercaptopropionic acid (MPA) was used as a stabilizer an...... hiện toàn bộ
Development of a robust reporter gene assay for measuring the bioactivity of OX40‐targeted therapeutic antibodies
Luminescence - Tập 36 Số 4 - Trang 885-893 - 2021
Meng Li, Lan Wang, Chuanfei Yu, Junzhi Wang
AbstractOX40 plays a prominent role in the onset and development of solid tumors, and OX40‐targeted monoclonal antibodies (mAbs) have entered clinical trials for various tumors. Bioactivity determination of therapeutic mAbs is of great significance in product quality, however, mechanism of action‐based bioassays to determine the bioactivity of anti‐OX40 mAbs is sti...... hiện toàn bộ
Flow injection analysis of tetracyclines using inhibited Ru(bpy)32+/tripropylamine electrochemiluminescence system
Luminescence - Tập 20 Số 1 - Trang 8-15 - 2005
Yong-Qiang Pang, Hua Cui, Hai-Song Zheng, Guo-Hui Wan, Li-Juan Liu, Xiao-Feng Yu
Flow system for the automatic screening of the effect of phenolic compounds on the luminol–hydrogen peroxide–peroxidase chemiluminescence system
Luminescence - Tập 26 Số 6 - Trang 571-578 - 2011
André R. T. S. Araújo, Fernando Maya, M. Lúcia M.F.S. Saraiva, José L. F. C. Lima, Wolfgang Frenzel, Vı́ctor Cerdà
ABSTRACTIn this work, an automated flow‐based procedure for the screening of the effect of the different phenolic compounds on the chemiluminescence (CL) luminol–hydrogen peroxide–horseradish peroxidase (HRP) system is presented. This procedure involves the combination of multisyringe flow injection analysis (MFSIA) and sequential injection analysis (SIA) technique...... hiện toàn bộ
