Influence of polymer and QD concentration on the properties of QDNBs.
| NO. | [QDs] (µM)a | [polymer] (mg/mL)a | TEM diameter (nm) | DLS diameter (nm) | PDI | NsQDNB (QDs/Bead) |
|---|---|---|---|---|---|---|
| QDNB1 | 8.0 | 10 | 86.4 | 134.4 | 0.063 | 1238.4 |
| QDNB2 | 4.0 | 5 | 74.2 | 118.4 | 0.096 | 841.5 |
| QDNB3 | 2.0 | 2.5 | 63.6 | 91.82 | 0.100 | 529.9 |
| QDNB4 | 1.0 | 1.25 | 51.3 | 83.41 | 0.105 | 278. 1 |
aPolymer and QDs concentration in the oil phase. The aqueous phase consists of 1% SDS, and oil/water phase volume ratio is 1:6. The amplitude of the sonicator was set at 50%, the sonication cycle was 10 s sonication, 10 s pause, and repeat for 10 times. NsQDNB is the number of QDs in each nanobead.
