Developing Wrinkled Surface to Achieve Low-Cost Photoelectrochemical Biosensor and Study the Interplay between LSPR of Nanoparticles and Semiconductive Quantum Dots

The emergence of photoelectrochemical (PEC) biosensors has opened the door to achieve biosensors with a low limit-of-detection as PEC technique offers reduced background signals 1,2. As a result, researchers are trying to use PEC technique to achieve low-cost and ultrasensitive biosensors. In this work, we proposed a novel method for fabricating flexible, low-cost PEC sensor substrates. Exploiting wrinkled surfaces, we have shown an increase in …
