Triboelectric nanogenerators for next-generation wearable health monitoring

NanoWerk.com - Wed, 07/31/2019 - 12:05
Dozens of nanotechnology research groups worldwide are working on the development of triboelectric nanogenerators (TENGs) for harvesting energy from mechanical vibrations. The huge interest in TENGs stems from their ability to convert ambient mechanical energy into electricity for powering wearable electronics, energy generation using sound, sensor networks, removing air pollution with nanogenerator-enhanced air filters, implantable medical devices, and other small systems. A recent article comprehensively reviews the recent advances in TENG-based health monitoring.

Jellyfish-based nanofiber/nanoparticle wound dressing

NanoWerk.com - Tue, 07/30/2019 - 18:15
Researchers demonstrate the ease of use of jellyfish biomass as a biodegradable and biocompatible raw material for producing antibacterial mats. They report the successful electrospun-based preparation of novel composite biocompatible nanofibers based on jellyfish biomass. The antibacterial properties of the resulting nanofiber mats were enhanced by incorporating silver nanoparticles within applying an in situ bio-template synthesis that the team developed. This work suggests exploiting the jellyfish as an accessible, cheap and valuable renewable material that can be used in various applications, such as cosmetics, wound dressings, artificial skin, and bioplastics.

New nanoparticle combination therapy shows effective resuscitation for massive hemorrhage

NanoWerk.com - Tue, 07/30/2019 - 16:24
Scientists successfully resuscitated rabbits with coagulopathy from severe hemorrhagic shock using hemostatic nanoparticles and oxygen-carrying nanoparticles, which respectively stopped bleeding and delivered oxygen to the systemic tissues and organs. There are no effective therapies for such massive hemorrhage so far, thereby the combination therapy using two kinds of functional nanoparticles maybe desirable in future emergency trauma care.

Advanced optoelectronics with graphene-based mixed-dimensional van der Waals heterostructures

NanoWerk.com - Mon, 07/29/2019 - 15:47
Among 2D materials, graphene is considered as one of the important components in many van der Waals (vdWs) heterostructure assemblies due to its high carrier mobility, good environmental stability, tunable work function, and mature processing technique. Besides the contact between different 2D atomic layers, the passivated, dangling-bond-free surfaces of 2D crystals can bond together with other dimensional materials through vdWs force. Consequently, fabrication of mixed-dimensional vdWs heterostructures could be carried out through hybridizing 2D crystals with 0D dots or particles, 1D nanostructures, or 3D bulk materials.
