Abstract

The culturing of Aplysia neurons on porous silicon (PS) substrates to form a neuron-semiconductor contact was discussed. The neurons cultured on PS generated action potentials and maintained normal membrane properties. The mechanisms for utilizing the photoluminescence (PL) from PS to transduce electrical activity of the neurons into optical signals were also investigated. By using aqueous salt-based liquid solution contact, it was found that photoluminescence quenching occurred for cathodic current polarization. The results show that the decay time of the photoluminescence was slow due to diffusive nature of the process.
