The application of nanotechnology to cardiovascular nanomedicine

nanostructuredNanostructured systems have the potential to revolutionize both preventive and therapeutic approaches for treating cardiovascular disease. Given the unique physical and chemical properties of nanostructured systems, nanoscience and nanotechnology have recently demonstrated the potential to overcome many of the limitations of cardiovascular medicine through the development of new pharmaceuticals, imaging reagents and modalities, and biomedical devices. A recent review offers an outline of critical issues and emerging developments in cardiac nanotechnology.

Structural engineering of 2D-layered energy materials

nanosheetsTwo-dimensional (2D) energy materials have outstanding physical and chemical properties in contrast to their bulk counterparts. This is particularly true for charge storage devices such as lithium-ion batteries and supercapacitors. Unfortunately, when directly applying these 2D nanostructured materials for energy storage, there is still a significant challenge as they may have serious self-restacking leading to decreased active surface areas and sluggish ion transport kinetics. Researchers have now developed an effective interlayer engineering strategy to improve sodium ion transport in 2D nanosheets via controlled organic intercalation.

Alkaline earth metal vanadates: new anode materials for high performance sodium-ion batteries

nanograinSodium-ion battery, as an emerging battery technology beyond lithium-ion battery, has attracted great research interests recent years. Sodium-ion batteries have a similar configuration and electrochemical reaction processes with lithium-ion batteries. But the Na resources are much more abundant and cost-effective than Li resources, which makes sodium-ion batteries highly promising as next-generation energy storage devices, especially for large-scale energy storage. However, the practical application of Na-ion batteries is still not currently realized.

Assembling colloidal matter with an opto-thermophoretic strategy (w/video)

colloidsResearchers have developed various assembly approaches, including self-assembly and electric/magnetic field directed assembly, to build diverse colloidal matters. These techniques feature high throughput but with limited structural configurations. Specifically, some of the techniques highly rely on the physical performance of the colloidal particles. In new work, researchers have developed a versatile colloidal assembly strategy - termed opto-thermophoretic assembly (OTA) - to build artificial colloidal matter in a wide range of colloidal materials, sizes, and shape.

A nanotechnology approach to augment nerve regeneration

neuronsIn recent years, researchers working in neurobiology have been intrigued by the idea of microtubule-stabilizing drugs as a therapy to augment nerve regeneration. In new work, scientists show that a better idea is to increase the amount of the dynamic parts of the microtubules. They do this by reducing the levels of fidgetin, a protein that normally exists in nerves to keep the dynamic parts of microtubules from elongating too much.

Proposal for a new legislative framework for regulating nanomaterials

regulationsThere is a proposal for a new legislative framework tailored for nanomaterials and their applications called Registration, Evaluation, Authorization, Categorization and Tools to Evaluate Nanomaterials - Opportunities and Weaknesses (REACT NOW). REACT NOW is the first attempt to present a truly comprehensive and transparent regulatory decision-making framework tailored for nanomaterials. This proposal for new legislative framework combines registration, evaluation, authorization and categorization of nanomaterials.

Detecting food allergens with a keychain reader

keychain_readerThe incidence of food allergies, food sensitivities, and autoimmune reaction is increasing worldwide, particularly among children. Designing a novel device for food testing, researchers have developed a portable, point-of-use technology for rapid, integrated exogenous antigen testing (iEAT). The system consists of a disposable allergen extraction device and an electronic keychain reader for sensing and communication. The extraction kit captures and concentrates food antigens from dispersed food. Captured allergens are then quantified using the miniaturized key-chain reader.

Perovskite-based flexible image sensor array (w/video)

sensorPerovskite materials have attracted great attention in the fields of optoelectronics due to their significant optoelectronic properties. So far, the applications of perovskite thin-films have been limited to solar cells because the required high-definition patterning for optoelectronic devices hadn't been achieved yet. Now, though, researchers in Korea have realized a high-resolution spin-on-patterning (SoP) process for the fabrication of optoelectronic devices arrays such as image sensors.
