Biosensors

Biosensors are powerful analytical tools for bioanalytes detection in a sample type from any source (human, food, environment or agriculture).

During analysis, when the sample (analyte) are added to a biosensor, its bio-recognition elements (enzymes, aptamers, antibodies and ligands) selectively react with the analyte by means of biochemical reaction (electrochemical, colour, light, etc.) and its signals are further processed through a transducer device (e.g., reading the colour intensity, light emission, current or voltage produced), to provide a quantitative or semiquantitative analyte level in the sample.

Focus Areas

The Biosensor Laboratory at the Robert Bosch Centre for Cyber-Physical System was set up with the mission to develop – in collaboration with academic and industrial partners – “affordable biosensors for medical diagnostics, water quality, food quality, environmental toxins and agriculture” which can bring social impact. Examples of our sensors are:

  • Colorimetric immuno nano sensors
  • Colorimetric biochemical sensors
  • Biochemical wearable sensors

Research Projects

Affordable and robust E.Coli biosensor development for rapid detection of faecal contamination in water
