Small nanoparticles bring big prospect:The synthesis,modification,photoluminescence and sensing applications of carbon dots
文献摘要:
As a new type of carbon-based fluorescent nanomaterials,carbon dots(CDs)are provided with the advan-tages of small size,excellent photoluminescence(PL)property,easy surface modification,robust stability,good water solubility and biocompatibility,which endow them with great potential in sensing.In this re-view,we first describe the preparation of CDs from different starting materials via various techniques,and pre-/post-modification strategies to modulate their PL properties.Second,we outline the optical proper-ties of CDs,including UV-vis absorption and PL,especially the PL mechanisms of CDs are presented in de-tail from the size effect,molecular state,surface state and defect state.Third,we summarize the research progress of CDs in sensing environmental pollutants,bioactive substances,biological microenvironments,bacteria and viruses via different mechanisms.In addition,we envision the future development trends and prospects for CDs-based nanosensors.We believe that this type of small nanoparticles will bring about big prospect in the near future.
