DESCRIPTION:Ioanna Zergioti\, National Technical University of Athens\, Ph
 ysics Department\, Iroon Polytechneiou 9\, 15780 Zografou\, Athens\, Greec
 e\nDuring the last decade\, laser based techniques have received significa
 nt attention as direct\, cost-effective and high resolution printing/patte
 rning techniques applied in a variety of applications including sensors\, 
 microelectronic devices\, cell printing\, etc.. Among them\, Laser Induced
  Forward Transfer (LIFT) exhibits inherent advantages\, in terms of high s
 patial resolution of the printed and/or processed patterns\, enabling the 
 maskless (direct) deposition of highly resolved features of materials incl
 uding biomolecules\, and Carbon nanotubes (CNTs)\, which can serve as sens
 ing elements of chemical and bio-sensors. The versatility that LIFT presen
 ts\, offers the capability of its implementation for the fabrication of a 
 variety of sensing devices\, i.e. resistive\, amperometric\, transistor-ba
 sed\, optical sensing\, and on different substrates. It is also used as an
  advanced functionalization process of the sensors surface without the nee
 d for intermediate layers\, or chemical functionalization techniques\, tha
 t often require treatment with toxic solvents and hazardous chemicals. In 
 this work\, examples of chemical and biosensors fabricated based on the LI
 FT technique will be presented. In particular photosynthetic\, enzymatic\,
  and DNAzymebiosensors will be presented for the detection of hazardous co
 ntaminants in food products and water. In addition\, laser based fabricati
 on of chemical sensors with sensing elements CNTs\, usually in the form of
  polymer composites\, or graphene and other graphene-based materials (grap
 hene oxide\, reduced graphene oxide) used for the detection of humidity an
 d organic volatile compounds (ethanol\, xylene) will be shown.
