Is Mechanosensing an Active Process?
Is Mechanosensing an Active Process?Types of MechanosensingWhen a cell periodically tests its external environment, a mechanical signal is converted to a chemical signal across the cell membrane. Adhesion receptors located on the external cell membrane [...]
How does the cytoskeleton transmit mechanical forces?
How does the cytoskeleton transmit mechanical forces?It is clear that mechanical forces and structural cues influence cell behavior by regulating signal processes. These signals go on to alter gene expression and reorganize the cytoskeleton and [...]
How is Energy Transferred Across the Cellular System?
How is Energy Transferred Across the Cellular System?Cellular systems function at a nanometer level and use a highly dynamic set of components. Both of these factors act as primary constraints that prevent the generation of [...]
Protein Localization
Protein LocalizationIn order for subcellular processes to be carried out within defined compartments or cellular regions, mechanisms must exist to ensure the required protein components are present at the sites and at an adequate concentration. [...]
Spatiotemporal control of DNA, RNA, protein and lipid synthesis
Spatiotemporal control of DNA, RNA, protein and lipid synthesisIn eukaryotes, synthesis of DNA, RNA, proteins and lipids is performed in a spatiotemporal manner. Each molecule is produced within specialized organelles or compartments with strict regulatory [...]

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.
