L2: Laboratory for microsystems in biomedical and environmental applications

Head of the Laboratory: Dr. Carmen Moldovan

Interest in specific objectives:

  • FP7-ICT-2009-5 Objective ICT-2009.3.9: Microsystems and Smart Miniaturised Systems. Target outcomes: a) Heterogeneous Integration; c) Application-specific microsystems and smart miniaturised systems(Lab-on-Chip (LoC) platforms);

Main areas of expertise:

  • Development of a large area of microsensors: chemoresistive, resonant gas sensors, accelerometers, microarrays, ISFET (Ion Sensitive Field Effect Transistors) sensors, electrodes for biological sensors, microprobes for recording of electrical activity of cells and tissues;
  • software simulations/modelling, using MEMS–specific CAD software (CoventorWare, CADENCE);
  • technological development and electrical characterisation;
  • microfluidic platforms simulation and realization including tubes, microfluidic connectors and reservoirs, pumping system and microsensors integration;

Participation in International co-operations

  • INTEGRAMplus (“Integrated MNT platforms and services – Service Action”) – FP6 IP, IST, 2006 – 2008, coordinator QinetiQ, Malvern, UK;
  • TOXICHIP (“Development of a toxin screening multiparameter on-line biochip system”) – FP6 STREP, IST, 2006 – 2009, coordinator Tyndall National Institute, Ireland;
  • Network of Excellence: 4M (“Multi-MaterialMicro Manufacture: Technologies and Applications”) – FP6 NMP NoE, 2004 – 2009, coordinator Cardiff University, UK;

Service offer
