Laser-blasted biopsies escape damage Jun 24, 2015

(with audio) Picosecond infrared laser ablation extracts biosamples damage-free.

Technology update

'Green' nanocapsules kill bacterial biofilms

Silica nanoparticles encapsulating natural essential oils could be used as disinfectants but may also help in wound healing.

Ferroelectric capacitor goes flexible

New device might find applications in wearable electronics, health-monitoring systems and ultradense information-storage systems that mimic the structure of the brain.

Spectrometry reaches mass-consumer simplicity

The first ever spectrometer to use quantum-dot materials demonstrates the possibility of devices as small, cheap and simple as smart-phone cameras.

Taking the heat off silicon optical devices

Pulsed laser deposition offers a cooler CMOS-compatible approach for fabricating photoluminescent silicon nanocrystal fabrication.

Graphene/hBN metastructure goes hyperbolic

Researchers succeed in controlling "hyperbolic polaritons" in a hybrid metastructure made from carbon sheets and hexagonal boron nitride.

Nano-cartography: knowing where to look

Mapping aids navigation. Now a well-stocked tool box of approaches provides information on how electronic, optical, mechanical and magnetic properties vary in nanosystems, with ever more refined techniques for accruing insights into the interplay of different system parameters.

Electron microscopy reaches new heights

(with audio) Researchers gathered at the inauguration of the SuperSTEM 3 electron microscope in Daresbury, UK, told nanotechweb.org about their outlook for the equipment and its high-resolution spectroscopic and spatial capabilities.
