Physicists have succeeded in directly converting frequencies to higher ranges in a common magnetic material without the need for additional components.
Researchers propose a convenient and low-cost strategy to prepare a printable and recyclable liquid-metal-microgel ink by encapsulating liquid metal microdroplets into alginate microgel shells for directly printing flexible electronics on various substrates.
Researchers have developed a novel technique to quantify the helical morphology of gold chiral nanorods. Such nanoparticles exhibit unique properties in a sense that they can change the circular polarization of light. In many cases, these properties are believed to be caused by the helical (or 'screw-like') morphology of the nanoparticles, but until now it was very difficult to objectively analyze their shape. This methodology is the first building block towards a fundamental ...
Radiation therapy is one of the cornerstones of cancer therapy. However, some types of tumor respond little or hardly at all to radiation. If it were possible to make tumor cells more sensitive, treatment would be more effective and gentler. Researchers have now succeeded in using metal oxide nanoparticles as 'radiosensitizers' - and in producing them on an industrial scale.
A new approach to send 'friendly' nanoparticles into a patient's blood stream has shown promising results by modifying the surface of these potential drug, vaccine or cancer treatment delivery objects to encourage the best result.
Research has identified that the frequently used chemotherapy drug (5-FU or Fluorouracil) is 100 per cent more effective at targeting tumours (rather than surrounding tissues) when administered using an optimised liposomal formulation, in rats.
