The rewiring of photosynthetic biomachineries to electrodes is a forward-looking semi-artificial route for sustainable bio-electricity and fuel generation. Currently, it is unclear how the electrode and biomaterial interface can be designed to meet the complex requirements for high biophotoelectrochemical performance. Here we developed an aerosol jet printing method for generating hierarchical electrode structures using indium tin oxide nanoparticles. We printed libraries of micropillar array… 
Microfluidic chemostatic bioreactor for high-throughput screening and sustainable co-harvesting of biomass and biodiesel in microalgae
TLDR
The results demonstrated that microalgal cultures can be regulated to grow and accumulate lipids concurrently, thus enhancing lipid productivity in one step, and the developed on-chip culturing condition screening, which was more suitable for continuous bioreactor, was achieved at a half shorter time, 64-times higher throughput, and less reagent consumption.

Porous translucent electrodes enhance current generation from photosynthetic biofilms
TLDR
The enhancement of bioelectrochemical photocurrent harvesting using electrodes with porosities on the nanometre and micrometre length scale is reported, showing an increase by two orders of magnitude in the photocurrent when two cyanobacterial strains are grown on nanopourous transparent conducting substrates, compared to traditional solid substrates.
Design of Optimized PEDOT‐Based Electrodes for Enhancing Performance of Living Photovoltaics Based on Phototropic Bacteria
Living photovoltaics represent a growing class of microbial devices that are based on whole cell–electrode interactions. The limited charge transfer at the cell–electrode interface represents a
A three-dimensional hybrid electrode with electroactive microbes for efficient electrogenesis and chemical synthesis
TLDR
It is shown that an inverse opal-indium tin oxide electrode hosts a large population of current-producing Geobacter and attains a current density of 3 mA cm−2 stemming from bacterial respiration, which represents a benchmark current density for biohybrid electrodes.
Structure–Activity Relationships of Hierarchical Three-Dimensional Electrodes with Photosystem II for Semiartificial Photosynthesis
TLDR
It is found that the hierarchical structure of electrodes mainly influences the protein loading but not the enzyme activity, and photoactivity is more limited by light intensity and electronic communication at the biointerface.
Rational wiring of photosystem II to hierarchical indium tin oxide electrodes using redox polymers
Photosystem II (PSII) is a multi-subunit enzyme responsible for solar-driven water oxidation to release O2 and highly reducing electrons during photosynthesis. The study of PSII in protein film
Purification and properties of unicellular blue-green algae (order Chroococcales).
TLDR
Electron microscopic investigations, together with analytical data on cell wall composition and ribosomal structure, have revealed the common denominators, which are fundamental: bacteria and blue-green algae are the only organisms with cells of the procaryotic type.
