Pickering EmulsionsPickering emulsions, stabilized by various micro-or nanoparticles with different structures, morphologies or other characteristics, possess distinctive properties and versatile functions comparing with classical emulsions stabilized by surfactants.In recent years their applications, especially in the biomedical fi eld, have been carried out extensively and widely such as templates to prepare colloidosomes, as oral or topical delivery system.These emulsions are reviewed by J. Wu and G.-H. Ma on page 4633. RNA DetectionOn page 4662, a core-satellite structure was fabricated by H. Kuang and co-workers using partly-complementary-DNA-functionalized Au NPs of 35 ± 2 nm and quantum dots (QDs) of 6 ± 1 nm.The fl uorescence of the QD satellites was quenched after assembly with the Au core.In the presence of the target miR, the hairpin sequence of the coresatellite assembly was destroyed by DNA hybridization, leading to the restoration of fl uorescence. NanobiotechnologyThe State Key Laboratory of Biochemical Engineering (SKLBE) in the Institute of Processing Engineering, CAS is highlighted on the back cover.The laboratory has established micro-pore emulsifi cation, multi-shell formation and self-assembly technologies to bring great advances in nanobiotechnology.The developed nanoparticles or devices, with uniform-sizes and controlled structures, have exerted themselves in the fundamental research as well as the industrial applications on enzyme immobilization, high-throughput protein separation medium, controlled release and targeted diagnoses, and delivery of antigens, siRNA, and anti-cancer drugs.
