Semiconductor quantum dots (QDs) embedded into polymer microbeads are known to be very attractive emitters for spectral multiplexing and colour encoding. Their luminescence lifetimes or decay kinetics ...
The morphology of the beads was observed by field emission scanning electron microscopy (FE-SEM) before and after modification by the P(NIPAAm-co-BMA) copolymer hydrogel (Supplementary Fig. S1).
