Herein, a label-free multiplex photoluminescent silicon nanoprobe (PLSN-probe) is introduced as a potential substitute for quantum dots (QDs) in bioimaging. An inherently non-photoluminescent silicon substrate is altered to create the PLSN-probe, to overcome the major drawbacks of presently available QDs. Additionally, crystallinity alterations of the multiplane crystalline PLSN-probes lead to ...

The development of technology for objectively determining the ripeness plant seeds is an urgent task modern agricultural production. An alternative to existing methods optical photoluminescent technology, which characterized by high accuracy, selectivity, expressiveness, as well being remote and non-destructive. spectral characteristics excitation photoluminescence wheat, oat, corn during their...
