•Blood  transfusions – increasing compatibility by either targeting the donor’s antigen or antibodies or by blocking the recipients immune system for that specific blood group

•Targeted tumour blood vessel vasoconstriction

•Enzyme that digests the appendix (non-surgical appendectomy)

•Stopping spread of disease on the underground

•Hangover cure

•Skin clearing treatments

•An enzyme that changes D-glucose to L-glucose so it would not get metabolised and we do not get fat

•Genetically engineered bacteria which can produce enzymes to break down sweat oils to reduce acne. Would outcompete acne-causing bacteria (bacterial face cream for acne) 

•Modified bacteria with multiple disease related antigens for more effective vaccines

•Use RNAi to inhibit genes such as LUNA to inhibit signs of skin aging

•Telomere caps preventing degradation

•Quick genetic blood test for markers of disease (think 60 second HIV test)

•Bioengineering bacterial to biomark particular diseases e.g. diabetes, cancer

•Modify bacteria that might cause Parkinson’s (a study from a couple of years ago) so they don’t produce the substances that cause the disease 

•Stopping spread of disease on the underground

•Mutate enzymes within bacteria that use pollutants as a substrate- converting pollutants into less harmful products. Possibly featuring a containment system that allows air to filter through but contains the modified bacteria (so it is not released into the environment). This could be positioned on skyscrapers etc

•Inert gas supersaturation detection.

•Enzyme that revives dead plant cells in paper

•Using bacteria to clean up contaminated water

•I believe there was a species of bacteria currently found to be able to degrade plastics. Maybe we could contact the discovering university for a sample and coax it to secrete the enzyme responsible? It could be both analysed for its mechanism of action and sold as a produce.

•More eco-friendly cleaning

•Doing something for smog- releasing a spray of some sort that cleans it up

•Wetware computing and creating organic servers that could be added to organisms

•Increasing (vector?) load size

•The mind machine interface

•Applying optogenetics for something good

•Self replicating tissue (not sure what kind of tissue this is – cleaning tissue or human tissue?)

•Improve CRISPR/Cas9 targeting of specific tissue,  therefore decreasing risk when applying to a more  general  target. Simplify the applying method.
