This study introduces miniaturized biochips with microelectronic sensors for multiparametric, on-line analysis of living cells. This approach accelerates drug screening and reduces the need for animal testing by enabling functional validation of compounds.

Area of Science:

  • Biotechnology
  • Pharmacology
  • Bioengineering

Background:

  • Gene databases and expression studies accelerate drug target identification.
  • High throughput screening identifies leading compounds, but functional validation is a bottleneck.
  • In vitro cellular screening is crucial for preselecting drug candidates before expensive in vivo studies.

Purpose of the Study:

  • To develop and integrate microelectronic sensors into biochips for multiparametric, on-line analysis of living cells.
  • To enable functional testing of drug candidates in a physiologically relevant environment.
  • To improve the efficiency and reduce the cost of drug discovery and development.

Main Methods:

  • Development and adaptation of microelectronic sensors.
