Nanoribbon Biosensor-Based Detection of microRNA Markers of Prostate Cancer

Sensors, 2023
Prostate cancer (PC) is one of the major causes of death among elderly men. PC is often diagnosed later in progression due to asymptomatic early stages. Early detection of PC is thus crucial for effective PC treatment.
