How can physical scientists contribute to biomedical applications and healthcare?
With some nanomaterial-based medicines having entered the marketplace, and more on the verge of doing so, nanomedicine is expected to become an exciting playground for chemists and material scientists.
Philips has recently changed its focus from electronic components to healthcare innovations. Nature Materials talked to Hans Hofstraat about the reasons behind this choice and how it affected Philips Research scientists.
The low thermal conductivity of some thermoelectric materials is commonly attributed to rattlers — atoms trapped in oversized cages. Two independent studies now show that rattlers indeed reduce thermal conductivity to glass-like values.
Careful design of donor–acceptor polymer molecules with reversible redox properties gives access to polymer electrochromic displays with switchable absorption in the full visible range of the optical spectrum.
Using a known and widely used drug as a specific triggering agent, another drug can be released from a hydrogel. This route opens up the application of hydrogels in the targeted, controlled release of drugs in vivo.
Adding simple salts to colloidal solutions provides a method of controlling the migration of particles in microfluidic devices.
Artificial photosynthesis — splitting water with light — is an attractive way to make hydrogen, but what happens to the oxygen? A catalyst that aids in the efficient production of gaseous oxygen improves the viability of this approach.
