Castura (2023)

A Versatile Silicone Microtexture Fabrication Technique Using Laser-Engraved Micromolds

Description

Microtextured surfaces are a versatile tool for the scientific and makerspace communities alike. By utilizing this micro-surface topography, one can influence cell growth and behavior, mimic biological surfaces on inorganic material, or even create microfluidic systems for micro-technology and behavior studies. However, established microtextured fabrication methods are inaccessible due to the high-powered machinery that is required. Castura is a set of microtexture fabrication techniques that leverage makerspace resources, such as laser cutters and engravers, and commonly available materials to produce reliable, low cost, and high quality microtextures that can be applied as needed.
