Optical Tweezers to Study Viruses
, 2013 A virus is a complex molecular machine that propagates by channeling its genetic information from cell to cell. Unlike macroscopic engines, it operates in a nanoscopic world under continuous thermal agitation. Viruses have developed efficient passive and active strategies to pack and release nucleic acids.

How to Manufacture Photonic Metamaterials
Advanced Materials Technologies, EarlyView.Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Femtolitre Volume cryoEM Sample Preparation Using a Force‐Sensitive Microfluidic Cantilever
Advanced Materials Technologies, EarlyView.Cryogenic electron microscopy enables structural imaging of biological molecules, but current methods lack targeted extraction of subcellular content for direct vitrification. This study introduces a force‐sensitive microfluidic cantilever pipette that aspirates and dispenses femtolitre volumes from individual cells onto electron microscopy grids.

Bubble Printing of Anisotropic Clay Nanotubes
Advanced Optical Materials, EarlyView.Bubble printing patterns of lyotropic liquid crystal nanotubes form toroidal or linear patterns depending on laser movement and colloidal stability. Long nanotubes create radial filament bundles, while poor electrostatic repulsion hinders deposition.

Sketch and Peel Focused Ion Beam Patterning of Black Phosphorus for Mid‐Infrared Photonics
Advanced Optical Materials, EarlyView.“Sketch and peel” method nano‐fabricates black phosphorus (BP) with minimal damage. A focused‐neon ion beam “sketches” the pattern, followed by polyvinyl acetate‐based “peeling” to remove surrounding flakes. Thermal treatment preserves the mid‐infrared (MIR) emission of the isolated “Koala” structure, proving it as an enabling technology for future BP ...
