Singapore's A*STAR's Institute of Microelectronics (IME) has achieved breakthroughs in 3 fields including biosensor technology.

The institute will present three papers at the 2013 International Electron Devices Meeting (IEDM) to showcase these achievements.

In addition to biosensor technology IME achieved breakthroughs in   microelectronic-based cell enumeration platform and a three-dimensional (3D) microelectromechanical (MEMS) enabled laser source.

The new sensor is based on an innovative microring resonator design and features sensitivity capability that is offered at significantly lower cost than traditional label-free optical sensing systems.

Other features of this product include speed and multiplexing capability and all these make it a portable point-of-care (POC) diagnostic solution for timely intervention and better treatment outcome.

Automated counting of cells

A CMOS electrical-impedance-spectroscopy platform enables automated high speed counting of a large number of cell population with single cell resolution.

This ensures the elimination of the skill-intensive and laborious protocols involved in the manual cell differentiation, cell labeling and staining steps.

A*STAR notes that looking forward this platform can be used to identify tumor cells, relevant to clinical cancer management in a cost effective manner.

An on-chip integrated tunable laser with 3D micro-coupling system has been designed to generate light over a range of wavelengths. Claimed to be the smallest reported tunable laser fabricated by MEMS technology, the miniature integrated system can be readily integrated into high-density photonic circuits to achieve smaller form-factor.

Service providers can leverage the flexible wavelength range offered by the laser to cost-effectively expand system capacity in advanced wavelength division multiplexing (WDM) networks.

The expansion of system capacity supports high data packets at ultra fast speed. A*STAR adds that the laser can be used as a light source for next generation optical telecommunications and in other spectroscopy applications.
