Il 12 gennaio p.v. alle ore 15.30, alla Scuola Superiore di Catania, Giuseppe Arrabito terrà il seminario dal titolo “Printing biochips: from concepts to devices”.

“Microarray technologies are nowadays relatively mature, their development starting with the onset of high-density DNA arrays, then addressing with peptide and protein microarrays, and now prefiguring perspectives in the field of cellular arrays. Such high-throughput analytical tools are associated with smaller usage of sample volumes, decrease in use of reagents, rapid analyses, and increased sensitivity since, at the microscale, the chemical species have a shorter distance to diffuse than in conventional macroscale reaction vessels. Undoubtedly, the great advantage of these devices is their highly parallel nature and ability to interrogate hundreds to thousands of different sensing molecules in one experiment. The area of bioarray technology fabrication evolves along three different paths: patterning resolution, i.e., the decrease of the printed feature size on the slide from micro- until nanoscale; multiplexing, i.e., the increase of the number and of the density of tested biological targets (biomolecules or cells), and finally biochip design, i.e., the careful development of smart platforms able to collect and compute real time biological information.”
