Colloidal CdSe quantum dot (QD) core ensembles were photodimmed and allowed to recover in the dark using ambient thermal energy at a range of temperatures. Nonlinear thermal recovery is well described by a stretched exponential function, and further analysis yields

A number of different transfection reagents have been used for lentiviral vector production. We directly compared transfection buffers, DNA purification methods, chemical facilitators, and DNA concentrations to optimize production.
