An enzymogel that shows a novel type of phase-boundary biocatalysis is described by S. Minko, A. Voronov, et al. in their Communication on page 483 ff. The enzymogel particles combine biocatalysis involving enzymes in the particle, stimuli-triggered extracapsular biocatalysis, biocatalytic conversion of substrates contacting the enzymogel when the enzymes engulf the substrate, and stimuli-triggered reattachment of the released enzymes for their reuse (cover image courtesy of Ella Marushchenko).
Metal Organopolymeric Frameworks
In their Communication on page 414 ff., S. S. Lee, M. J. Zaworotko, J. J. Vittal et al. report a light- or heat-induced single-crystal-to-single-crystal interconversion of a ZnII coordination polymer.
The in situ synthesis of gold nanoparticles directly over a substrate surface by using inkjet printing followed by heating at 120°C is described by G. E. Jabbour et al. in their Communication on page 420 ff.
In their Communication on page 493 ff., L. Schröder et al. demonstrate that sensitive MRI cell tracking with switchable contrast can be achieved using cryptophanes (CrA) as xenon hosts.
