For the first time, this paper highlighted the method of detaching SU8-based carbon scaffolds from substrates using the acid treatment method. This finding provides a method to detach pyrolysed scaffolds from a substrate without the need to scrap the pattern. Briefly, the scaffold patterns were fabricated using photolithography and the pyrolysis method. Then, various attempts of detaching the carbon scaffold by using acids were investigated include H2SO4, HNO3, H2O2, and H2SO4/HNO3. Under 60 min treatment of HNO3 with stirring and non-stirring conditions has led to the detachments of pyrolysed SU8 without visible defect on the structure. This finding provides a free-standing SU8-based carbon scaffold that could be easily incorporated into hydrogel or other composites materials to form a conductive 3D in vitro model for biological application. Hence, these novel detachment methods provide new knowledge to detach SU8-based carbon scaffolds, while performing surface treatment to improve the surface properties of carbon scaffolds. The findings of this study improve the potential of SU8-based carbon scaffolds as tools in future biological applications. © 2022, Springer Nature Switzerland AG.
