How to turn every piece of clothing into an e-textile

NanoWerk.com - Wed, 07/31/2019 - 22:39
Researchers have fabricated textiles that can protect you from rain, stains, and bacteria, while they harvest the biomechanical energy of the user to power textile-based electronics. These omniphobic triboelectric nanogenerators can be incorporated into any fiber-based textile and be used to power wearable devices using energy harvested from human motion. The team also designed their nanogenerators with large-scale fabrication runs in mind, using embroidery as a technique compatible with conventional textile manufacturing techniques.

Actively swimming gold nanoparticles

ScienceDaily.com: Nanotechnology News - Wed, 07/31/2019 - 20:54
Bacteria can actively move towards a nutrient source -- a phenomenon known as chemotaxis -- and they can move collectively in a process known as swarming. Scientists have redesigned collective chemotaxis by creating artificial model nanoswimmers from chemically and biochemically modified gold nanoparticles. The model could help understand the dynamics of chemotactic motility in a bacterial swarm.

Liquid biopsy chip snares circulating tumor cells in blood drops from cancer patients

ScienceDaily.com: Nanotechnology News - Wed, 07/31/2019 - 19:41
Researchers have developed a chip made of carbon nanotubes that can capture circulating tumor cells (CTCs) of all sizes and types, and can do so with far greater sensitivity than existing technologies. The unique design of the device makes it possible to easily identify and even culture the captured cells, which could make it possible to detect early-stage tumors, predict the course of a cancer, and monitor the effects of therapy.

Leap toward robust binder-less metal phosphide electrodes for Li-ion batteries

ScienceDaily.com: Nanotechnology News - Wed, 07/31/2019 - 18:21
Researchers have successfully fabricated a binder-less tin phosphide (Sn4P3)/carbon (C) composite film electrode for lithium-ion batteries via aerosol deposition. The Sn4P3/C particles were directly solidified on a metal substrate via impact consolidation, without applying a binder. Charging and discharging cycling stabilities were improved by both complexed carbon and controlled electrical potential window for lithium extraction. This finding could help realize advanced lithium-ion batteries of higher capacity.
