Product Information

• Name: Lead sulfide StremDots„¢ quantum dot (PbS core - ~3nm), 10 mg/mL in toluene, 1000nm peak emission
• Brand: Biosynth
• Description: Lead sulfide quantum dots are semiconductor nanocrystals with a typical size of ~3 nm. They have high values for fluorescence, enzyme activities, and metal hydroxides. Lead sulfide quantum dots can be used to measure the activity of toll-like receptor (TLR) as an analytical method. The fluorescence intensity can be measured using electrochemical impedance spectroscopy (EIS). The fluorescence intensity is proportional to the TLR activity. Optical sensors can detect changes in the fluorescence intensity in real time, which is advantageous for applications that require rapid measurements. Lead sulfide quantum dots have high resistance against plasma mass spectrometry and thermal expansion. This means that they can be used to study the kinetics of reactions involving lead sulfide quantum dots and sodium citrate at different temperatures.
