The supramolecular engineering of a new family of hybrid gels coexisting with metal-organic framework (MOF) nano-particles created in situ is demonstrated by J. C. Tan and co-workers on page 4438. The rapid process of inorganic-organic self-assembly generates a hierarchical fiber network architecture, whose electrical conductivity and mechanical characteristics can be tuned to yield a range of bespoke soft matter with unconventional properties.
