Blue, Blue, Stable Optical Blue…
An international team suggest that coordination network materials, in particular MOFs, will be a useful platform for low-threshold lasers for diverse applications.
The Sound of Smallness
Researchers from the Massachusetts Institute of Technology, USA have introduced a simple strategy for making nanoparticles by the sonofragmentation of high‐aspect‐ratio 1D substrates.
Porous Silicon Nanovaccines Combat Cancer
Researchers from Finland and the USA, have developed two multistage nanovaccines constructed of two biomaterials and either a biological cancer cell membrane (CCM) or a model antigen
Particle Micromotors
Magnetically steerable, acid-resistant micromotors are developed that can be fabricated by electrostatic attraction between magnetite nanoparticles and gold microrods at pH ≈ 4.
Salt Drives Directional Particle Transport
Directional motion and transport can be achieved using a salt concentration gradient and an appropriately designed self‐assembling system, without substantial synthetic effort or a matrix.
Supercritical Lens Improves Optical Resolution at a Distance
Minghui Hong and colleagues report super-critical-lens (SCL) optical label‐free microscopy, which clearly distinguishes a pattern with a feature size of 65 nm in air and with a 55 μm working distance.
The Missing Link: 3D Bioprinting with Non-Viscous Inks
Jason Burdick and colleagues from the University of Pennsylvania, USA, and Tsinghua University, China report a general method for 3D bioprinting of photocrosslinkable hydrogels without limitations on ink viscosity.
Hot Stuff: Direct Ink Writing of Mesoscale Eutectic Architectures
Jennifer Lewis and colleagues report a new process for creating mesoscale eutectic architectures, known as high operating temperature direct ink writing (HOT‐DIW).
Switching Liquid Repellent Surfaces
Researchers from Pennsylvania State University, USA, have now revealed a magnetically transformable surface that can reversibly switch between the lotus and the pitcher plant modes
