Detection and identification of plant pathogenic fungi have relevant implications for both food safety and human health, and require fast and easy-to handle diagnostic techniques. In this context, we report the design and development of a fluorescent array-based sensor, containing different organic receptors, able to detect selectively Penicillium italicum, Alternaria alternata and Fusarium sacchari. The detection of these pathogenic fungi can be performed using a smartphone, leading to the first example of detection of microscopic fungal plant pathogens by fluorescent array using a smartphone as detector. This study represents a proof-of-concept for the realization of practical sensoristic devices able to detect pathogens in plant products and food or in environmental samples, in order to guarantee food and human health security.

Abstract

Detection and identification of plant pathogenic fungi have relevant implications for both food safety and human health, and require fast and easy-to handle diagnostic techniques. In this context, we report the design and development of a fluorescent array-based sensor, containing different organic receptors, able to detect selectively Penicillium italicum, Alternaria alternata and Fusarium sacchari. The detection of these pathogenic fungi can be performed using a smartphone, leading to the first example of detection of microscopic fungal plant pathogens by fluorescent array using a smartphone as detector. This study represents a proof-of-concept for the realization of practical sensoristic devices able to detect pathogens in plant products and food or in environmental samples, in order to guarantee food and human health security.
