The change in fluorescence intensity of mercaptopropionic acid\u2010capped cadmium sulphide (MPA\u2010CdS) QDs is attributed to the increasing concentration of Amox. The results show that the fluorescence quenching of QDs by Amox takes place through both static and dynamic types of quenching mechanism. The fluorescence quenching of QDs with increase in concentration of Amox shows the linear range between 5\u00a0\u03bcg\u00a0ml<jats:sup>\u22121<\/jats:sup> and 30\u00a0\u03bcg\u00a0ml<jats:sup>\u22121<\/jats:sup> and the limit of detection (LOD) is 5.19\u00a0\u03bcg\u00a0ml<jats:sup>\u22121<\/jats:sup>. There is no interference of excipients, which are commonly present in pharmaceutical formulation and urine samples. For the practical application approach, the developed method has been successfully applied for the determination of Amox in pharmaceutical formulations and urine samples with acceptable results.<\/jats:p>","DOI":"10.1002\/bio.3271","type":"journal-article","created":{"date-parts":[[2017,4,21]],"date-time":"2017-04-21T07:39:13Z","timestamp":1492760353000},"page":"918-923","source":"Crossref","is-referenced-by-count":29,"title":["Fluorescence\u2010based sensor for selective and sensitive detection of amoxicillin (Amox) in aqueous medium: Application to pharmaceutical and biomedical analysis"],"prefix":"10.1002","volume":"32","author":[{"given":"Samadhan P.","family":"Pawar","sequence":"first","affiliation":[{"name":"Fluorescence Spectroscopy Research Laboratory, Department of Chemistry Shivaji University  Kolhapur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laxman S.","family":"Walekar","sequence":"additional","affiliation":[{"name":"Fluorescence Spectroscopy Research Laboratory, Department of Chemistry Shivaji University  Kolhapur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dattatray B.","family":"Gunjal","sequence":"additional","affiliation":[{"name":"Fluorescence Spectroscopy Research Laboratory, Department of Chemistry Shivaji University  Kolhapur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dattatray K.","family":"Dalavi","sequence":"additional","affiliation":[{"name":"Fluorescence Spectroscopy Research Laboratory, Department of Chemistry Shivaji University  Kolhapur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anil H.","family":"Gore","sequence":"additional","affiliation":[{"name":"Fluorescence Spectroscopy Research Laboratory, Department of Chemistry Shivaji University  Kolhapur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prashant V.","family":"Anbhule","sequence":"additional","affiliation":[{"name":"Fluorescence Spectroscopy Research Laboratory, Department of Chemistry Shivaji University  Kolhapur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shivajirao R.","family":"Patil","sequence":"additional","affiliation":[{"name":"Fluorescence Spectroscopy Research Laboratory, Department of Chemistry Shivaji University  Kolhapur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Govind B.","family":"Kolekar","sequence":"additional","affiliation":[{"name":"Fluorescence Spectroscopy Research Laboratory, Department of Chemistry Shivaji University  Kolhapur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,4,21]]},"reference":[{"key":"e_1_2_7_2_1","volume-title":"United States Pharmacopoeia 30 National Formulary 25","author":"Lawrence","year":"2007"},{"key":"e_1_2_7_3_1","unstructured":"Indian Pharmacopoeia The Indian Pharmacopoeia Commission Ghaziabad2003."},{"key":"e_1_2_7_4_1","volume-title":"Clinical Periodontology and Implant Dentistry","author":"Lindhe J.","year":"2000"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.3390\/s16010056"},{"key":"e_1_2_7_6_1","first-page":"1037","volume":"3","author":"Manzoor A.","year":"2011","journal-title":"Int.
