Scientists use light to switch viral activity and deliver cargoes to cells

Light is helping scientists control both the infectivity of viruses and gene delivery to the nuclei of target cells. The researchers have developed a method to use two shades of red to control the level and spatial distribution of gene expression in cells via an engineered virus.

Nano-walkers take speedy leap forward with first rolling DNA-based motor

Physical chemists have devised a rolling DNA-based motor that's 1,000 times faster than any other synthetic DNA motor, giving it potential for real-world applications.

Photonic 'sintering' may create new solar, electronics manufacturing technologies

Engineers have made a fundamental breakthrough in understanding the physics of photonic 'sintering', which could lead to many new advances in solar cells, flexible electronics, various types of sensors and other high-tech products printed onto something as simple as a sheet of paper or plastic.

Researchers fabricate a virtually perfect single layer of hexagonal boron nitride

A new era of electronics and even quantum devices could be ushered in with the fabrication of a virtually perfect single layer of 'white graphene'.

Daguerreotype exhibit explores nanotechnology's role in preserving local history

In 1839, Louis-Jacques-Mande Daguerre unveiled one of the world's first successful photographic mediums: the daguerreotype. The process transformed the human experience by providing a means to capture light and record people, places, and events. The University of Rochester is leading groundbreaking nanotechnology research that explores the extraordinary qualities of this photographic process.

The faster the separation speed, the better the separation resolution - nanotechnology makes it possible

Researchers invented a new separation technology overcoming the conventional separation concept.

Chemists craft molecule that self-assembles into flower-shaped crystalline patterns

The National Science Foundation has awarded $1.2 million to three research groups to advance research on self-assembling molecules and computer-aided design software required to create the next generation of solar cells, circuits, sensors and other technology.
