Optically active semiconductor nanopores for parallel molecule detection

We propose a detection scheme forcharged molecules or particles based on optically excitedsemiconductornanopores. By means of numerical simulations, we show that the band gap of thesemiconductornanopore can be tuned allowing actuation by light. Molecules translocating through thesemiconductornanopore modulate thefluorescence from thenanopore enabling molecule detection. Our approach will enable us to perform a parallel readout of a translocating molecule without the need of chemical modification of the translocating molecules.
