* We set out to synthesize mercury-sulfide quantum dots templated by Bovine serum albumin. Multiple attempts proved unsuccessful. However, in the process we discovered a reproducible synthesis that yields, what appears to be, a protein-based film suspended in aqueous solution. This page summarizes all of my experiments conducted during the 2014-2015 academic year, as well as my optimized synthesis procedure for producing these HgS-BSA films (aka the "Quick Synthesis"). | * We set out to synthesize mercury-sulfide quantum dots templated by Bovine serum albumin.

* You will find UV-Vis and Fluorescence data for the first few syntheses (JCS 1-3) in an excel file on DropBox. This file also contains FTIR data from JCS 16. The sample was stuck to the membrane that was used to filter it, so a spectra of the membrane is also included. | * You will find UV-Vis and Fluorescence data for the first few syntheses (JCS 1-3) in an excel file on DropBox.

Project Summary
Original Protocol
"Quick" Protocol (15 min Synthesis)
Note: These solutions have a tendency to bump on the rotovap. Watch carefully and be ready to break vacuum temporarily in the beginning!Filtration ProtocolI conducted vacuum filtration once using a membrane filter (Supor-450, 47mm, 0.45μm). This worked to separate the gels from the solution, however do not leave the product on the membrane to dry--it will get stuck the membrane. Summary of Syntheses Attempted
