Encapsulated nanoparticles can create bright colors by amplifying particular wavelengths of light. These microcapsules could offer a new, non-toxic and long-lasting source of color for paints and electronic displays.
If you've ever suffered the misery of food poisoning from a bacterium like Shigella or Salmonella, then your cells have been on the receiving end of 'nanoinjectors' - microscopic spikes made from proteins through which pathogens secrete effector proteins into human host cells, causing infection.
Ali Shakouri, the Mary Jo and Robert L. Kirk Director of Purdue University's Birck Nanotechnology Center, is the 2014 recipient of the prestigious THERMI Award for his contributions to the field of semiconductor thermal management.
Move over, nanotechnologists, and make room for the biggest of the small. Scientists at the Wyss Institute have built a set of self-assembling DNA cages one-tenth as wide as a bacterium. The structures are some of the largest and most complex structures ever constructed solely from DNA.
Combining nanodrug-based chemotherapy and cryoablation provides an effective strategy to eliminate cancer stem-like cells the root of cancer resistance and metastasis, which will help to improve the safety and efficacy of treating malignancies that are refractory to conventional therapies.
