QVH is a group of autoclaved water soluble alloy CdSSe/ZnS or CdSe/ZnS core/shell quantum dots with amphiphilic polymer coating. QVH has been autoclaved at 121°C for 30 min, which is suitable for experiments that require enzyme-free conditions.
Their reactive group of QVH is carboxylic acid. The zeta potential of QVH is from -30mV to -50mV. Their organic layers consist of a monolayer of oleic acid/octadecylamine and a monolayer of amphiphilic polymer. The thickness of the total organic layers is about 4 nm. The hydrodynamic size of the QDs is about 8-10 nm larger than their inorganic core size measured by TEM.
QVH is very stable in most buffer solutions in the pH range of 5-10.
