Encapsulation of dye molecules into a silica framework promises to overcome some of the functional limitations of free organic dyes. In the present work, structural stability of tetramethyl rhodamine-dextran (TMR-dex) doped silica nanoparticles (NPs) prepared through a reverse microemulsion method is probed with respect to observable changes of NP morphology and dye leaching from the NPs during their storage and post-synthesis modification. It is found that NPs synthesized with the higher (of… CONTINUE READING
