Oxford Nanoimaging Ltd. has announced the Nanoimager, a desktop, nanoscale imaging system for live cells. The Nanoimager can measure the dynamics of molecular interactions and structural transitions such as the detection of protein subunit assembly or the real-time observation of DNA synthesis. The unit has been engineered from the bottom up for optimum single-molecule imaging functionality. It may be operated on a regular desk or bench without the need for extra antivibration or environmental isolation.
