A process for producing polymer-supported metal nanoparticles involves confinement of metal nanoparticles in polymeric nanotubes or nanosheets in an aqueous environment using hydrophobic reactants. Metal nanoparticles supported in the polymeric nanotubes or nanosheets are substantially monodisperse and have an average particle size of 4 nm or less. The polymer-supported metal nanoparticles are useful in fuel cells, sensors, bioanalysis, biological labeling or semi-conductors, especially as catalysts.

This invention relates to gels that undergo either oscillatory stepwise expansion or oscillatory expansion and contraction. An oscillatory reaction occurs within the gel, changing the conditions of the gel, and causing the gel to expand and optionally contract. The gels may be used for oscillatory release of a chemical agent.
