Assessment of WO electrode modified with intact chloroplasts as a novel biohybrid platform for photocurrent improvement.

The present work describes an easy way to prepare a Chloroplast/PDA@WO biohybrid platform based on the deposition of chloroplasts on WO substrate previously modified with polydopamine (PDA) film as anchoring agent. The use of PDA as an immobilization matrix for chloroplasts, and also as an electron mediator under LED irradiation, resulted in enhanced photocurrents. The use of the chloroplasts amplified the photocurrent, when compared to the bare substrate (WO).
