Processes happening within cells can be difficult to monitor without harming the cell, however, optical nanosensors can be incorporated into cells without appreciable damage. Kim and coworkers (S Kim, B Kim, V Yadavalli & M Pishjko, Anal Chem 2005, 77, 6828) reported the fabrication and characterisation of poly-(ethylene glycol) hydrogel spheres containing the enzyme horseradish peroxidase. The particles were made using a reverse emulsion photopolymerisation process yielding partic...
