| Research Abstract |
We constructed two types of photo-controlled nano-pore devices based on PYP photoreceptor-fused staphylococcal pore-forming toxin alpha-hemolysin. The both PYP-fused devices had the similar photocycle as wild type PYP and inhibited the transmission efficiency of ions through the sheep red blood cells membrane under light irradiation. These PYP-fused devices will serve molecular basis for nano-pore devices of which activity is easy to be arbitrarily tuned by light irradiation.
