Biohybrids
Organisms created by combining biological and non-biological elements. In this case, microbes and semiconductors working together.

Biosynthetic
Relating to the production of complex compounds within living organisms or systems.

Semiconductors
Materials that have properties between conductors (like metals) and insulators (like glass) and are used to control electrical currents.

Carbon dioxide (CO2) fixation
The process of converting carbon dioxide into organic compounds, like sugars, by living organisms.

Photoelectrochemical current mapping
A technique used to visualize and measure how electrons move in a system when it is exposed to light.

Hydrogenases
Enzymes in cells that play a crucial role in the metabolism of hydrogen, a key element in many biological reactions.
Independent Research Ideas

The role of light in biohybrid efficiency
Investigate how different wavelengths of light affect the efficiency of CO2 conversion in biohybrids. This could lead to optimized light conditions for maximum bioplastic production.

Bioplastics in everyday life
Explore the potential applications of bioplastics produced by solar-powered microbes in consumer products. How can they replace conventional plastics, and what are the challenges?

Comparative study of biohybrid systems
Compare the efficiency of different biohybrid systems in converting CO2 to valuable products. This could involve studying various combinations of microbes and semiconductors.

Environmental impact assessment
Analyze the environmental benefits and potential drawbacks of large-scale bioplastic production using solar-powered microbes. Consider factors like land use, energy consumption, and byproduct creation.
