Abstract: Printing of micro- and nanofibers directly from a polymer drop with unprecedented order, direct writing of sharp/straight edges, and easy multijets electrospinning are demonstrated and reported. Experimental fabrication of patterns embedded with active molecules ensures that functionalized patterns preserve their functionalities after the thetered pyro-electrospinning (TPES) process. Results regarding the use of smart patterns for keeping alive and viable cultured cells are discussed. This study opens the way to innovative optogenesys analysis, guiding light for generating or transporting optical/electronic signals from and to cells.
