Research Interests
Microfluidics, Micro-optical systems for live cell imaging
Our laboratory is primarily interested in the application of micro/nano fabrication technology to biological science. We exploit standard and advanced micro-fabrication tools in order to design and produce systems and devices for cell culturing and imaging. Examples of such devices are: topographically and/or chemically micro-textured environments, microfluidic devices, micro-optical systems and more.
We are also interested in developing microfluidic devices for FTIR spectromicroscopy of living cells. FTIR is an imaging technique that is intrinsically label-free and requires minimal sample preparation; when coupled with microscopy and high brilliance IR sources it allows the acquisition of chemical maps at a resolution which is diffraction limited. Absorption of IR photons induces very low or no damage at all, therefore it is in principle possible to observe for prolonged time the behaviour of living cells. Our research activity is intended to develope microfludic platforms suitable for FTIR (key parameters are optical transparency and low IR absorption) while keeping cells alive and healthy; a beneficial feature provided by micro-fabrication approach is the possibility to control of the chemical environment at the micro-scale.

Biography
Dr Gianluca Grenci joined MBI in 2012 as a research fellow and head of the Micro Fabrication Core facility. Previously he was employed at the LILIT micro/nano fabrication group (IOM-CNR, Trieste, IT) for a total of 6 years, during which he was mainly involved in the design and fabrication of microfluidic devices for synchrotron-light related spectroscopic techniques, such as SAXS and FTIR. He thus developed extensive practical knowledge on all the major lithographic technologies (UV and EB lithography, wet/dry etching, soft-lithography, thin films deposition), plus some less usual and/or more advanced technique, such as X-ray Lithography and LIGA.
He did his PhD in the field of applied superconductivity, in a project aimed to develop a current cryo-comparator (CCC) using high critical temperature superconductors of the cuprate family (YBCO) in the form of a thick film deposited onto a large area, complex shaped silver substrate.
