No passivation process is required to generate spatially regulated biosurfaces. As Bong Soo Lee and co ‐ workers show in their work featured on the front cover, patterns of proteins and cells are efficiently generated without employing a passivation process on the intrinsically activated, non ‐ biofouling copolymer ‐ coated gold surface, which was synthesized by surface ‐ initiated activators regenerated by electron transfer–atom transfer radical polymerization (SI ‐ ARGET ATRP) with 2 ‐ aminoethyl methacrylate hydrochloride (AMA) and oligo(ethylene glycol) methacrylate (OEGMA).

The article focuses on the characteristics of microbial spores. Microbial spores, a robust and dormant state formed upon the deprivation of essential nutrients, can persist in the soil for many years until they encounter a germination signal. The cell viability of microbial spores can be kept up almost permanently by shuttling between vegetative cells and spores. The article reports the first example of micropatterns of recombinant Bacillus thuringiensis spores (BT Spores), the surface of which displays heterologous proteins. It also demonstrates the successful germination of the recombinant BT spores patterned on the surface.

Facile tunability of physicochemical properties of ionic liquids (IL), particularly imidazolium ions bearing simple alkyl appendages as cations, has led to intense interest in IL as an alternative to conventional organic solvents in a range of synthesis, catalysis, electrochemistry and liquid-liquid extractions. Recent developments include their use for biopolymers,chemosensors for specific ions, determination of acidity scale and formation of nanosized metal particles and hollow metal oxide microspheres. The availability of potentially hydrophobic and hydrophilic IL attests to the ease in the manipulation of their physical properties.

Front Cover: The division timing of yeast cells is controlled chemically, as a step towards realization of artificial spores, by encapsulating individual yeast within polymeric multilayers of catechol‐grafted polyethyleneimine and hyaluronic acid pairs by the layer‐by‐layer technique and subsequently cross‐linking the layers.
