Singapore, Jan 22, 2008: Thailand to host the fourth international conference on sensors, AsiaSense 2009, from July 29-31, 2009 at the Imperial Queen’s Park Hotel, Bangkok. The National Science and Technology Development Agency (NSTDA), Thailand organizes the conference.

 

Given the confirmed high profile speakers participation, the conference is expected to attract renowned scientists and engineers working in the highly dynamic field of sensors research, development and application. One of the keynote speakers, Prof Dr Anthony P F Turner, indicated that biosensors are defined as analytical devices incorporating a biological material (e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, natural products), a biologically derived material (e.g. recombinant antibodies, engineered proteins, aptamers) or a biomimic (e.g. synthetic catalysts, combinatorial ligands, imprinted polymers) intimately associated with or integrated within a physicochemical transducer or transducing microsystem, which may be optical, electrochemical, thermometric, piezoelectric, magnetic or micromechanical.

 

Biosensors usually yield a digital electronic signal, which is proportional to the concentration of a specific analyte or group of analytes. While the signal may in principle be continuous, devices can be configured to yield single measurements to meet specific market requirements. Biosensors have been applied to a wide variety of analytical problems including in medicine, drug discovery, the environment, food, process industries, security and defense. The emerging field of bioelectronics seeks to exploit biology in conjunction with electronics in a wider context encompassing, for example, biological fuel cells and biomaterials for information processing, information storage, electronic components and actuators. A key aspect is the interface between biological materials and electronics.
