Nanotechnology materials: opportunities and challenges go hand in hand

green_nanomaterialsNovel materials designed and fabricated with the help of nanotechnologies offer the promise of radical technological development. Many of these will improve our quality of life, and develop our economies, but all will be measured against the overarching principle that we do not make some error, and harm ourselves and our environment by exposure to new forms of hazard. A publication explores recent developments in nanomaterials...

Smart materials become 'alive' with living bacteria in supramolecular assemblies

modified_bacteriaSupramolecular chemistry deals with molecular building-blocks that interact with each other in a dynamic manner, similar to what is seen in nature. Taking advantage of this, several 'smart' materials have been developed for biomedical applications by careful design of these building-blocks. These materials have especially interesting properties like self-healing and responsiveness to light and electricity. Researchers have...

A quick and simple blood test to detect early-stage cancer

protein_coronaA novel nanoparticle blood test detects an overall increase of human immunoglobulin G (IgG), including the tumor-specific autoantibodies, adsorbed to a gold nanoparticle surface. While this test may not be able to identify the specific type of cancer, it may potentially be able to detect early stage tumor-induced immune responses associated with a broad spectrum of cancer types, making this test potentially a universal screening...

Nanoparticle shape can drastically enhance MRI signals

nanostarsTypically, in clinical formulations of Magnetic Resonance Imaging (MRI) contrast agents, gram quantities of Gd(III) are needed to achieve sufficiently high contrast for examination. That's why the research imaging community is interested in developing new formulations of contrast agents able to bridge the gap between high contrast imaging of contrast agents dosed at low concentrations. In new work, researchers report a new...

Fast molecular cargo transport by diffusion

nanomotorIn new work, researchers have utilized diffusion as an effective transport mechanism for DNA nanotechnology. These findings contribute a new aspect to be considered for the design of future DNA motors, molecular machines, and nanorobots as they provide a simple way to transport molecules over distances of potentially several 100 nm; which is much faster than when using conventional DNA walkers or motors, which make many small...

Nanotechnology to the rescue: Replacing chemical disinfectants with engineered water nanostructures

water_nanostructureTrying to develop chemical free disinfection techniques, researchers are currently exploring the effectiveness of a nanotechnology based intervention method for the inactivation of foodborne and spoilage microorganisms on fresh produce and on food production surfaces. This method utilizes Engineered Water Nanostructures (EWNS) generated by electrospraying of water. These EWNS are 25 nm in diameter; remain airborne in indoor...

One-step detection of pathogens and viruses with high sensitivity

bacteriumResearchers have developed a magnetic bead based sensor that combines magnetic separation (MS) and magnetic relaxation switch (MRS) for one-step detection of bacteria and viruses with high sensitivity and reproducibility. Compared to conventional assays for detection of bacteria and viruses, this novel MS-MRS assay is easy to operate without laborious pre-treatment, purification and can be adaptable to point-of-care tests...

Chemically enhanced 2D material makes excellent tunable nanoscale light source

microdisk_light_emissionMolybdenum disulfide's (MoS2) semiconducting ability, strong light-matter interaction and similarity to the carbon-based graphene makes it of interest to scientists as a viable alternative to graphene in the manufacture of electronics, particularly photoelectronics. In particular, MoS2 has excellent optical properties when deposited as a single, atom-thick layer - unlike graphene, it emits light when excited; albeit relatively...
