The procedure is according to [http://onlinelibrary.wiley.com/doi/10.1002/smll.201200760/abstract;jsessionid=59DC726F3FB89E8F4C1C42470213080B.f01t01|Protein-Directed Synthesis of NIR-Emitting, Tunable HgS Quantum Dots and their Applications in Metal-Ion Sensing.]. | ||
==Procedure== | |||
*5mL of 5mM HgNO3--HgNO3 was not fully disolving so HgCl2 was used instead | |||
*5mL BSA (15mg/mL) | |||
*final pH around 9 (adjusted by 1M NaOH)--The pH was around 10 in this reaction. Not enough calculations were taken when adding the NaOH. | |||
*The variac was set on 55/100, temperature is around 115C | |||
*vigorous stirring | |||
*stir for 8-12 hours, till color is pale yellow | |||
*Eleni followed the same procedure, however her solution was left in room temperature | |||
*The nitrogen gas and the water supply under the hood was all set for the reflux reaction. | |||

DescriptionI started working this semester, Fall 2014, under the supervision of Dr. Hartings, with James and Eleni on Quantum Dots again. The project was started last semester in Chemistry-571, however not enough results were collected. This semester we will be working on synthesizing QDs again using Mercury instead. The procedure is according to Synthesis of NIR-Emitting, Tunable HgS Quantum Dots and their Applications in Metal-Ion Sensing.. Procedure
CalculationsCalculations for the HgCl2 and for the BSA are from Eleni's notebook
