In an article featured on the cover of the March issue of Nature Nanotechnology, Mauro Ferrari of The University of Texas Health Science Center at Houston presented a proof-of-concept study on a new multistage delivery system (MDS) for imaging and therapeutic applications. This discovery could go a long way toward making injectable drugs more effective.
Physicists at the Georgia Institute of Technology have made important findings regarding gold on the nanoscale. They found that applying an electrical field on a surface-supported gold nanocluster changes its structure from a three-dimensional one to a planar flat structure. In another paper, they relate their discovery that gold in this size regime can be made magnetic through oxygenation of gold nanowires.
Materials known as photonic crystals could form the building blocks of future optical computers and micro-scale communications devices. Scientists have developed a low-cost and versatile way to make photonic crystals, and combined them in ways that bring optical 'transistors' a step closer.
A University of Pittsburgh-led research team developed a process wherein the ability to conduct electricity can be turned on and off at nanoscale dimensions. This capability holds promise for more powerful and compact information technologies including ultra-high density information storage, reconfigurable logic devices, single-electron devices, and quantum computers.
In November 2007, Which?, the UK consumer advocat group, commissioned a short survey among the general public which highlighted low levels of awareness for nanotechnologies and how they are being used. Following on from this, Which? undertook an additional research project with consumers - the Citizens' Panel on Nanotechnologies - which was published yesterday.
Professors Neal Skipper and Franco Cacialli, of the London Centre for Nanotechnology (LCN) and the Department of Physics & Astronomy, University College London (UCL), have been awarded a GBP200,000 laboratory refurbishment grant to help them develop alternative fuel supplies for transport and electricity generation.
Die Bundesanstalt f. Arbeitsschutz und Arbeitsmedizin (BAuA), das Bundesinstitut f. Risikobewertung (BfR) und das Umweltbundesamt (UBA) haben eine gemeinsame Forschungsstrategie 'Nanotechnologie: Gesundheits- und Umweltrisiken von Nanopartikeln' erarbeitet.
A team from University College London has developed a new medical device which will make the early detection of breast cancer more cost effective and easier to administer. The team plans to use magnetic nanoparticles and an extremely sensitive magnetometer called the 'HistoMag' to detect cancerous cells in samples of breast tissue.
A University of Pennsylvania professor is exploring an approach to nanotechnology that will allow circuit theory to operate in an entirely new regime - one where 'current' is no longer defined as the movement of electrons and holes, but instead as an electromagnetic wave.
Under the joint auspices of the Ministry of Sciences & Technology (MOST) and China Association for Science & Technology, more than 1,600 Chinese scholars including CAS and CAE members, chief scientists of the National Basic Research Program (dubbed 973 Program) and directors of national key labs, have voted for China's top 10 events basic research in 2007.
