Variety of colours, printing and final models.
A collection of the material samples with different colours from my homemade natural dyes, alongside a monoclonal antibody test prototype made from the biopolymer. This image was taken whilst in a discussion about the properties of the material in the application of medical testing. The coloured material seen here were made from cabbage, spinach, turmeric, spirulina, black bean, beetroot, onion skins, and avocado.

Printing onto the material
Experimenting with the use of alternative analogue printing techniques, I investigated different ways of transferring images onto the biopolymer. Liquid light and cyanotypes successfully developed clear and detailed images; producing entirely photosensitive biopolymer using liquid light emulsion which was added to the polymer composition. This is a more sustainable alternative to photopaper when working in the darkroom.

Final model: Disposable Monoclonal Antibody Test
Final design outcome for a disposable monoclonal antibody test, with QR code for recording test results and instructions printed using liquid light. The test is an all-in-one model with antibody suspension fluid held inside the block, reducing the number of pieces in the test kit. The test is made from my sustainable biomaterial to reduce single use plastics.

Final model: Reusable swab test
An alternative covid test design, with a reusable handle and lid. The user could then order a pack of tests, containing the swab, cartridge, and an antibacterial wipe, which could then be used to disinfect the reusable piece of the test after use to keep it clean for the next use.
