A device for diagnosing Xylella fastidiosa
The microsensor-based prototype diagnostic device aims at detecting Xylella fastidiosa that lives and reproduces inside raw sap conductors of olive trees and which causes relevant alterations, often fatal, to host plants.
The device developed by researchers, being very sensitive, can detect the pathogen on trees in Salento, with very rapid analysis times. This is a first important tool for experts in this sector to complete a diagnosis on the field.
Xylella is usually detected by lab techniques, while in this study “the two traditional methods were compared with the new test developed on electrochemical biochips. Results are comparable to those of traditional tests, but have significant advantages in terms of costs and time spent for analysis”, said CNR researcher Serena Chiriacò.
“The development of new diagnostic techniques” said Andrea Luvisi, a researcher from the University of Salento “is a useful monitoring resource and an essential activity for epidemic containment”.
Once industrialized, the proposed technology will provide a method of analysis entirely developed in Salento, useful for implementing a large-scale screening.
