Toshiba Develops MEMS Based Technology For Injecting Nanoparticles In Cells

Toshiba announced the development of a manipulation technology for injecting nanoparticles in cells by using subtle vibration generated by a micro electro mechanical system (MEMS).

Compared with conventional techniques using laser beam to affect cells physically, the newly developed technology has advantages, such as simultaneous manipulation of numerous cells. Expected applications in the field of biotechnology include a medical analytical tool for investigating the reaction of cells to physical effects and clarifying their detailed properties, and, looking further ahead, a technique for affecting specific cells.

The principle of this technology is as follows. Vibration produced by MEMS causes nanoparticles in a liquid to adhere to cell surfaces. When vibration is applied continuously to nanoparticles adhering to cell surfaces, vibration is converted to thermal energy that affects cell surfaces physically, resulting in injection of nanoparticles into the cells.

Using Toshiba's advanced semiconductor process technology, the company has fabricated a nanoparticle manipulator with a water-repellent MEMS-based diaphragm consisting of numerous micro dishes (20 Ám x 20 Ám) arranged in a lattice format. In an experiment involving the application of a water droplet containing yeast cells and silica (glass) particles, the principle of this technology was verified.

ASUS Introduces TM-21 Mini Tower Chassis

ASUS Introduces TM-21 Mini Tower Chassis

ASUS today introduced the TM-21 chassis series, which adopted simple yet elegant minimalistic design. The chassis also features some thermal innovations.

The TM-21 is available in two colors, black and white. All drive bays and front input/output ports are covered by a front-bezel that utilizes a paint-coating method that is used on grand pianos to deliver a smooth and elegant look.

The TM-21 series provides space for two 8cm rear fans (one is upgradeable to 9cm) and one 8cm front fan. For fast ventilation, the rear hexagon-shaped holes and side panel offer larger area for smooth airflow and heat dissipation.

The chassis accommodates three 3.5" internal drive bays and input/output support for two 3.5" and two 5.25" drives. Other expansion specifications include COM2 port, data security lock, USB 2.0 and IEEE1394.


  • Dimension w/Bezel: 170x355x395mm
  • MB Form Factor: mATX
  • Drive Bays: External 5.25" x 2, External 3.25" x 2, Internal 3.25" x 3
  • System Fans: Rear: 80mm x 2 or 92mm x 1, Front: 80mm x 1
  • Expansion Slots: 4
  • Front I/O Options: w/o front I/O, w/USB 2.0 x 2 + Audio x 2, w/USB 2.0 x 4 + Audio x 2 + IEEE 1394 x 1
