Abstract
The synthesis and confinement of graphitic nanoparticles (carbon dots) in the nanoscale solvent channels of cross-linked lysozyme single crystals is used to prepare novel biohybrid luminescent materials. Co-sequestration of acridine orange within the biohybrid crystals from acidic or neutral solutions yields FRET-mediated phosphors emitting white or green light, respectively. The results offer a route to new types of tuneable multicolour luminescent materials based on microcrystalline host-guest energy-transfer systems. Crystal glow: Novel host-guest type bio-hybrid materials are prepared by synthesising graphitic carbon dots within nanoporous cross-linked lysozyme crystals. Subsequent co-sequestration of acridine orange dye within the biohybrids triggers donor-acceptor mediated charge transfer yielding microcrystals with tuneable fluorescence.
