Abstract
In this work, we present a simple, ultrasensitive and rapid cost-effective sensing technique based on Mercaptosuccinic acid (MSA) capped CdTe/ZnS core/shell (CS) quantum dots (QD) for the detection of toxic Hg(II) in aqueous media. The present system demonstrations a remarkably low detection limit of one pico molar (pM) which is the best-reported work till date. Here, the CdTe/ZnS \CS\ \QD\ is synthesized by using a simple one pot aqueous method, and are characterized with the help of UV
Microsoft is Ending Support for Windows 7
Microsoft will discontinue support for Windows 7 on January 14, 2020 which means Gamry will also be discontinuing support for Windows 7. If you are upgrading to Windows 10, like many companies and institutions, you need to be running Version 7 of our s oftware . Please note that only USB and Ethernet-based instruments can run in Version 7. Eligible users can download the latest version of our software through our online Client Portal .
If you haven't already registered your instrument, you can do so through the Client Portal .
Please email Technical Support if you have any questions regarding this transition. Please be sure to include your instrument model and serial number when contacting us.
