How are SiQDs characterized?

DLS, absorption and emission spectra, quantum yield. Certificate of analisys is provided for every production lot.

How is the concentration calculated?

SiQDs concentration is referred to the concentration of the silicon core only and it is calculated using the Lambert- Beer equation, using absorption coefficients (εabs) reported in Korgel et al., Chem. Mater. 2012, 24, 393−401.

What is the typical size of pegylated SiQDs?

Hydrodynamic radius is calculated via DLS instrument and is typical between 40 and 60 nm. Upon request we can provide related data.

Is it possible to customize the PEG terminal?

The COOH terminal can be functionalized with amide or ester coupling.
