WebThis review describes the challenges and various strategies for signal amplification of sensors that lead to higher sensitivity via antibody immobilisation techniques and … WebSignal amplification. In the initial response to injury, platelets adhere to damaged blood vessels, responding to the exposure of collagen from the vascular epithelium. Once adhered they degranulate, releasing stored secondary agents such as ADP and ATP, and synthesized thromboxane A2. These amplify the response, activating and recruiting ...
