Like a carpet for cells, micropatterned polymeric nanosheets are developed toward local cell delivery. The nanosheets directed morphogenesis of retinal pigment epithelial (RPE) cells and allowed for the injection of an engineered RPE monolayer through syringe needles without loss of cell viability. Such an ultrathin carrier has the promise of a minimally invasive delivery of cells into narrow tissue spaces.

A fascinating approach to the development of a hybrid micro-bio-robot is presented by Samuel Sanchez, Oliver G. Schmidt and Veronika Magdanz on page 6581. Rolled-up microtubes are used to capture single sperm cells and remotely control them to a desired location. These microbio-robots are useful for the controlled guidance of sperm cells, which is a promising feature towards the development of new assisted-fertilization techniques.

Photosynthesis provides a paradigm for the conversion of sunlight to chemical energy in the form of hydrogen (H2), where hydrogenases catalyze the reduction of protons to H2 with remarkable activity. A simple and exceptional artificial photocatalyst, Nih-CdSe/CdS core/shell hybrid, made in situ from CdSe quantum dots and nickel salts under mild condition is described on page 6613 by Li-Zhu Wu and co-workers. The synthetic strategy is general and the artificial photocatalyst holds promise for light capture, electron transfer, and catalysis at its surface in water, leading to a self-healing system for H2 evolution in harmony.
- Graphene Nanoribbons: Dense Arrays of Highly Aligned Graphene Nanoribbons Produced by Substrate-Controlled Metal-Assisted Etching of Graphene (Adv. Mater. 45/2013) (page 6469)

Fabrication of graphene nanoribbon arrays by substrate-controlled cutting of graphene during metal-assisted etching is demonstrated by Hiroki Ago and co-workers on page 6562. The proposed method allows for large-area production of highly dense arrays of aligned nanoribbons from a single graphene film. This is expected to facilitate the large-scale integration of graphene nanoribbons into electronic device applications. The image conceptually illustrates the cutting process of the graphene by the metal nanoparticles.
- Batteries: Encapsulated Monoclinic Sulfur for Stable Cycling of Li–S Rechargeable Batteries (Adv. Mater. 45/2013) (page 6546)

On page 6547 Do Kyung Kim, Jang Wook Choi and co-workers describe a highly aligned and carbon-encapsulated sulfur cathode synthesized with an AAO template that exhibits a high and long cycle life, and the best rate capability based on the complete encapsulation of sulfur (physical) and implementation of the monoclinic sulfur phase (chemical).
