Tumor-on-a-chip: new strategies of in-vitro cancer cell culture

Compartir
This project proposes a framework for creating microfluidic devices for cell culture, inspired by organ-on-a-chip and tumor-on-a-chip and manufactured largely with fused filament fabrication. This unique technology promises to simplify and minimise manufacturing costs, make it easier to adapt culture chips to the current application, be watertight, have an adjustable flow, be wire-free, and serve as a platform for future bio-inspired designs. To make the models work despite the required miniaturisation factor, the sizes of the various components and sections were adjusted using stress testing. To seal the parts and ensure that the system was impermeable, chloroform was used; it was also used to promote layer adhesion (and hence strength) and to smooth the pieces' texture to reduce cell adhesion. PLA, PETG, and PCTG are utilised to manufacture the majority of the models, TPU is used for the filtering system. PMMA caps for the chips must be made before culture tests to precisely monitor cells. These will be cut with a laser cutter and joined with chloroform. Cell culture and viability testing will determine the device's efficacy and future potential ​
