A Fluorescent Chemosensor for Dihydrogen Phosphate Ion Based on 2‐[2‐Hydroxy‐4‐(diethylamino) phenyl]‐1H‐imidazo[4,5‐b]phenazine‐Fe3+ Ensemble

09-Dec-2014 | Taibao Wei, Guiyuan Wu, Bingbing Shi, Qi Lin, Hong Yao, Youming Zhang, Chinese Journal of Chemistry, 2014

Abstract A long wavelength emission fluorescent (612 nm) chemosensor with high selectivity for H2PO4− ions was designed and synthesized according to the excited state intramolecular proton transfer (ESIPT). The sensor can exist in two tautomeric forms ('keto' and 'enol') in the presence of ...


Unique Fluorogenic Ratiometric Fluorescent Chemodosimeter for Rapid Sensing of CN− in Water

27-Oct-2014 | Ajit Kumar Mahapatra, Kalipada Maiti, Saikat Kumar Manna, Rajkishor Maji, Chitrangada Das Mukhopadhyay, Bholanath Pa ..., Chemistry - An Asian Journal, 2014

Abstract A new benzimidazole‐spiropyran conjugate chemosensor molecule (BISP) has been synthesized and characterized by 1H NMR spectroscopy, mass spectrometry (ESI‐MS), and elemental analysis. The two isomeric forms (BISP↔BIMC) were shown to be highly selective and sensitive to CN− among the ...


New Route for Fast Detection of Antibodies against Zoonotic Pathogens in Sera of Slaughtered Pigs by Means of Flow-through Chemiluminescence Immunochips

06-May-2013 | Klaus Wutz; Verena Katharina Meyer; Silke Wacheck; Piotr Krol; Manfred Gareis; Christina Nölting; Friedhelm Struck; ..., Analytical Chemistry, 2013

The research on fast screening methods for antibodies against zoonotic pathogens in slaughter animals is important for food safety in farming and meat-processing industries. As a proof-of-concept study, antibodies against the emerging zoonotic pathogen hepatitis E virus (HEV) and enteropathogenic ...


Evaluation of an Arsenic Test Kit for Rapid Well Screening in Bangladesh

25-Sep-2012 | Christine Marie George; Yan Zheng; Joseph H. Graziano; Shahriar Bin Rasul; Zakir Hossain; Jacob L. Mey; Alexander va ..., Environmental Science & Technology, 2012

Exposure to arsenic in groundwater via drinking remains unabated for millions of villagers in Bangladesh. Since a blanket testing campaign using test kits almost a decade ago, millions of new wells have been installed but not tested; thus affordable testing is needed. The performance of the ...


Amperometric enzyme electrodes for the determination of volatile alcohols in the headspace above fruit and vegetable juices

09-Aug-2012 | Claudia Schlangen, Martin Hämmerle, Ralf Moos, Microchimica Acta, 2012

We have investigated two amperometric biosensors for the determination of volatile alcohols in the headspace of fruit juices and vegetable juices. One type of sensor is based on the use of alcohol dehydrogenase (ADH) and the detection of NADH (at +300 mV vs. Ag/AgCl with phenothiazine as redox ...


ELISA-on-a-chip for on-site, rapid determination of anti-rabies virus antibodies in canine serum

30-Jul-2012 | Jin-Woo Jeon, Sung-Min Seo, Hee-Soo Kim, Jin-Sik Oh, Youn-Kyoung Oh, Gun-Woo Ha, Se-Young Hwang, Se-Hwan Paek, Sensors and Actuators B: Chemical, 2012

Massive pet vaccination has been needed in most countries to control rabies virus dissemination, and the antibody produced in the body must be monitored. To this end, standard analytical methods involving cell cultures infected with the virus were established; however, this analytical approach ...


Field Testing of Arsenic in Groundwater Samples of Bangladesh Using a Test Kit Based on Lyophilized Bioreporter Bacteria

20-Mar-2012 | Konrad Siegfried; Carola Endes; Abul Fateh Md. Khaled Bhuiyan; Anke Kuppardt; Jürgen Mattusch; Jan Roelof van der Me ..., Environmental Science & Technology, 2012

A test kit based on living, lyophilized bacterial bioreporters emitting bioluminescence as a response to arsenite and arsenate was applied during a field campaign in six villages across Bangladesh. Bioreporter field measurements of arsenic in groundwater from tube wells were in satisfying ...
