Due to that fact, the functions and properties of neurons are studied in cultures in vitro. This work attempts to manufacture a patterned transparent and biocompatible substrate based on a repulsive background of poly(ethylene) glycol (PEG) and an inkjet-printed adhesive molecule of a collagen/poly-L-lysine (PLL) mixture above it. This ink, totally designed in this study, allows printing specific patterns where neurons will adhere. It was possible to get a characterized repulsive background and a printable adhesive molecule, obtaining biocompatible printed patterns.5 p.application/pdfengcc-by-nc-nd (c) Altarriba , 2018http://creativecommons.org/licenses/by-nc-nd/3.0/es/Xarxes neuronals (Neurobiologia)Formació de patrons (Física)Impressores (Ordinadors)Treballs de fi de grauNeural networks (Neurobiology)Pattern formation (Physical sciences)Computer printersBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
