Initial ideas
Idea 1: Bioprinted Multilayer Dynamic Material
Layer 1(bottom):Iridescent layer
DNA origami to create static nanostructure that can assemble into dynamic microstructures that create the iridescent layer
Layer 2(middle): Pigment Layer
Different pigments could be expressed in response to different conditions/stimuli
Layer 3(Top): Melanin Layer
Reversible proteins that can toggle between 2 states controlling how much melanin is expressed.This enables different degrees of light to pass through, therefore exposing a range of pigments and iridescence
Idea 2: Freeze dried personalized nutrition and flavorings for astronauts (Deep Space Food Challenge)
Freeze dried cell free systems to produce micro, macro and phytonutrients + flavors and smells on demand
Advantages:
High shelf life
Compact/easy to store
Customizable to each astronaut’s needs and preferences
Safety: Doesn’t require live organisms
Enhances the food experience + offers more variety
