Nano shake-up: Routine handling can affect nanoscale drug carriers

A common assumption is that once a nanocarrier is created, it maintains its size and shape on the shelf as well as in the body. However, recent work has shown that routine procedures in handling and processing nanocarrier solutions can have a significant influence on the size and shape of these miniscule structures.

Piezotronics and piezo-phototronics leading to unprecedented active electronics and optoelectronics

Strain-induced polarization charges in piezoelectric semiconductors can effectively modulate the electronic and optoelectronic processes of charge carriers at the metal-semiconductor interface and p-n junction, which has resulted in both novel fundamental phenomenon and unprecedented device applications. The increasing research interests in the emerging field of piezotronics and piezo-phototronics has opened up opportunities for implementing novel applications such as adaptive human-electronics interfacing, active flexible/stretchable electronics, sensing, energy harvesting, biomedical treatments and optical MEMS.

New technique takes cues from astronomy and ophthalmology to sharpen microscope images

The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imaging technology rapidly corrects for these distortions and sharpens high-resolution images over large volumes of tissue.

Smartphone-readable particles could help crack down on counterfeiting

Researchers have invented a new type of tiny, smartphone-readable particle that they believe could be deployed to help authenticate currency, electronic parts, and luxury goods, among other products. The particles, which are invisible to the naked eye, contain colored stripes of nanocrystals that glow brightly when lit up with near-infrared light.
