Electrochemical Detection of Acetaminophen with Silicon Nanowires

February 8, 2018
Author(s)
Raja Ram Pandey, Hussain S. Alshahrani, Sergiy Krylyuk, Elissa Williams, Albert Davydov, Charles C. Chusuei
Acetaminophen (APAP) is an antipyretic, analgesic agent. Overdose during medical treatment poses a risk for liver failure. Hence, it is important to develop methods to monitor APAP in the body to avoid APAP toxicity. Here, we report an efficient and
