Engineering Biology & Materials ScienceIndustrial Biotechnology Challenge:
Biocomputers and cells and biosystems that interface, or function like, electronics.
- Technical Achievement: Enable selective ion channel (e.g., K+) activation in response to gene circuit initiation.
- Technical Achievement: Enable stronger cell-electronics interfaces through novel cell surface proteins and polymers.
- Technical Achievement: Enable swarm decision making, such as engineering large collections of cells that can apply an algorithm providing a statistical answer to a complex multivariable problem.
- Technical Achievement: Create artificial retina by integrating patterned cells or artificial cells sensitive to light with multi-electrode arrays.
Electrically conductive biofilms for radiofrequency shielding/cloaking.
- Technical Achievement: Enable synthesis of bio-wires such as cytochrome chains or ferritin chains which cross link between cells.
- Technical Achievement: Engineer sensing inputs that instruct the limit of biofilm layer thickness needed for specific frequency range.
- Technical Achievement: Enable persistence of materials with biological components in harsh or extreme environments.
Self-repairing materials for consumer products and the built environment.
- Technical Achievement: Engineer materials that retain their biological function during use that are triggered only as needed.
- Technical Achievement: Incorporate biocomponents to sense damage and repair through biofabrication of new material.
- Technical Achievement: Engineer materials that can trigger reorganization or alter interaction networks to fix gaps or damage in the material.
- Technical Achievement: Incorporation of microbes into construction materials (e.g., concrete, bricks) that produce mineral healing agents.
- Technical Achievement: Engineer controlled electrically- or magnetically-responsive materials where the physical properties are locked into the desired state.
- Technical Achievement: Engineer adhesives utilizing protein phase transitions that are reversible above and below certain temperatures.
- Technical Achievement: Develop biologically-derived adhesives that can bond together surfaces with different mechanical properties (e.g., soft-to-hard surface).
- Technical Achievement: Exploit biology to engineer self-assembling adhesives that spontaneously construct graded interfaces.
Packaging and building materials with adjustable strengths.
