A nanoelectromechanosensing approach to detect cancerous transformation of single cells

cell_with_microfilamentsSince diseased cells, such as cancer cells, frequently carry information that distinguishes them from normal cells, accurate probing of these cells is critical for early detection of a disease. Adding to these highly accurate methods for monitoring such alterations in single cells, researchers have now demonstrated a nanoelectromechanical procedure to relate the correlation between the mechanical stimulation of a cell's actin filaments and the electrical activities of ion channels to the cancerous state of the cell.

How the insurance market perceives nanotechnology risks

insuranceInsurance companies are major stakeholders capable of contributing to the safer and more sustainable development of nanotechnologies and nanomaterials. This is owed to the fact that the insurance industry is one of the bearers of potential losses that can arise from the production and use of nanomaterials and nanotechnology applications. Researchers have examined how the insurance market perception of nanotechnology can influence the sustainability of technological advances and insurers? concern for nanotechnology risks. They claim that, despite its role in sustaining technology development in modern society, insurers' perception on nanomaterials has been largely overlooked by researchers and regulators alike.

Ultraflat transfer method for graphene surface force balance

grapheneThe surface force balance (SFB) provides measurements of surface and colloidal forces in liquids such as electrostatic surface forces, van der Waals forces, and solvation forces. Until now, the SFB required mica sheets as the substrate for measurements. This was the only material available in an atomically smooth state over centimeter-scale areas as well as being optically transparent as required for the optical interferometry. By replacing the mica sheets with graphene, electrically conducting and atomically smooth surfaces for the measurement of surface forces have now been created.

Thermotherapy for pain management with a smart thermal patch

thermotherapyAdvanced health monitoring systems and healthcare devices will become an integral part of the Internet of Things. As a harbinger of things to come, nanotechnology researchers have now demonstrated a smart thermal patch which can be used for thermotherapy for pain management in a user interactive way. To fabricate the device, the researchers used CMOS technology to devise a silicon based smart thermal patch which is flexible and stretchable.

Leverage nanotechnology to speed up the energy transition

energy_transitionDrawing attention to the possible implications of extreme weather does not answer the question what we can really do about the risks of climate change, and who will drive fresh solutions. Science - including nanotechnology - is an important part of the answer, and we need human ingenuity to step forward. To accelerate the process and help to push the boundaries of usable energy solutions, the Exergeia Project backs potentially groundbreaking inventions and innovations in all fields of alternative energy.

Unlocking the potential of graphenes - functionalisation via plasma

plasma_reactorGraphene's properties appear to have almost limitless application potential, ranging from composite materials for the aerospace industry, next-generation batteries and supercapacitors, flexible displays and optical electronics and biosensors for applications in healthcare and medical devices. So why hasn't graphene, with the potential to vastly outperform the majority of currently available materials, been integrated into everything from wristwatches to ocean liners?

European Parliament agrees on moratorium on nanofoods and on a new legal definition of engineered nanomaterials

legalA majority of the members of the Environmental, Public Health and Food Safety (EHS) committee of the European Parliament approved several amendments to the draft regulation on novel foods, including one imposing a moratorium on novel foods containing nanomaterials. The EHS committee's amendments to the Commission's proposal show that the European Parliament and the European Commission clearly have two different approaches towards the regulation of nanotechnologies.

Superstable copper nanowire stretchable conductors

flexible_electronicsThe use of copper as an alternative electrode material to silver would reduce the cost of conductive inks. Nevertheless, copper nanowire conductors face a serious bottleneck for future practical use in flexible and stretchable optoelectronics: although they are nearly as conductive as silver, this conductivity is not stable. Researchers have now demonstrated conductive copper nanowire elastomer composites with ultrahigh performance stability against oxidation, bending, stretching, and twisting. This material offers a promising alternative as electrodes for flexible and stretchable optoelectronics.
