In this review we describe the main categories of substances reported in the World Anti-Doping Agency Prohibited List and how ABBs may contribute to their detection. Although several ABBs proposed in the last few years display limit of detections that are in principle matching the World Anti-Doping Agency requirements, their application in the framework of traditional' antidoping tests seems quite unlikely, mainly because of the still insufficient selectivity especially in the case of pseudo-endogenous' compounds, and on the lack of complete information regarding potential matrix effects in real samples and following their routine use. At the same time, ABBs could contribute to fill a significant information gap concerning complementary evidence that can be obtained from their use on the spot', as well as to preselect a risk population of individuals to be targeted for a full antidoping test; while in sport medicine they could contribute to obtaining analytical information of physiological relevance from the measurement of specific parameters or markers before, during and after physical exercise.

Abstract
Affinity-based biosensors (ABB) started to be considered also in sport medicine and doping control analysis because they are cheap, easy to use and sufficiently selective analytical devices, characterized by a reversible interaction with the analyte under investigation allowing the use of the same sensor for multiple analyses. In this review we describe the main categories of substances reported in the WADA Prohibited List and how affinity based biosensors may contribute to their detection. Although several ABB proposed in the last few years display limit of detections that are in principle matching the WADA requirements, their application in the framework of “traditional” antidoping tests seems quite unlikely, mainly because of the still insufficient selectivity especially in the case of “pseudo-endogenous” compound, and on the lack of complete information regarding potential matrix effects in real samples and following their routine use.
