BioCMOS company designs, develops, and supplies medical and environmental large scale integration circuits (LSI) with test equipment and software. We have supplied chips and test equipment to universities, national laboratories, and industrial laboratories for 10 years.

Biosensor Integrated Circuit

In view of the growing concerns about such issues as food security, health care, evidence-based care, infectious disease, and tailor-made medicine, a portable gene-based point-of-care testing (POCT) system is needed. For a system that anyone can operate anywhere and obtain immediate results, a new biosensor chip must be developed. Electrical detection using complementary metal-oxide semiconductor (CMOS) integrated circuits has great potential since it eliminates the labeling process, achieves high accuracy and real-time detection, and offers the important advantages of low-cost, compact equipment.



Biosensors are devices that combine a biological component (a recognition part) and a physicochemical detector component (a transducer). The recognition part can be constructed using enzymes, antibodies, cells, tissues, nucleic acids, and peptide nucleic acids. The transducer consists of potentiometric, amperometric, and impedimetric sensor circuits. A few biological molecules can be detected in a micrometer-scale region. Sample with milli liter is divided into pico liters, and detected in massively-parallel. We have developed such biomedical chips with high integration of micrometer-scale sensors. We have also developed stand-alone equipment. BCT-II is a general purpose equipment, suitable to research and development. BCT-III is a user friendly equipment specialized to specific application. BCT-II and BCT-III use same chips, so it is east to move from research and development to products.

Diagnostic and inspection by sound

Sound has been used for diagnostic of health, inspection of building defect, detection of piping water leak, and so on. SonicAnalyzer is a Windows application to analyze sound at frequencies between 10 Hz and 20 kHz. Its visualization, analysis, and customizable database will strongly support these diagnostic and inspection.
USB audio interface（16bit 48kHz) and state-of-art high-sensitive and low-noise microphone (patent pending) are supplied with SonicAnalyzer.



Scalogram is powerfull to visualize sound. The following picture shows heartbeat of healthy person and unhealth person.


SonicAnalyser supports several platoforms and remote diagnostic/inspection.
