Abstract: The present invention discloses a system and a method for detecting different developmental stages of fungi life cycle in postharvest crops. More particularly, the system comprises a measuring transducer, such as a CMOS photodetector and immobilized fungal nucleic acid strands. RNA from the tested postharvest produce sample is loaded onto the system of the present invention, and specific fungal mRNA transcripts anneal to the immobilized strands. A reporter strand conjugated to a signal-generating component further binds the mRNA transcripts, and when a detectable reaction is produced post binding, the transducer captures said reaction and converts it to measurable values, indicating the quantity, presence and the developmental stage of the fungus.

Abstract: An electrochemical lateral flow biosensor (ELFB) includes an ELFB strip and electronic detector unit coupled to the strip. The strip includes a polymeric hydrophobic membrane, conjugation pad, sampling pad, screen-printed electrode (SPE), and wick pad. The membrane provides a solid support and enables capillary flow along the strip. The conjugation pad is placed on the membrane at one end of the strip and contains adsorbed dehydrated labelled conjugate particles that are coated with the biorecognition element and coated or filled with the electrochemically active component. The sampling pad is placed on the conjugation pad and provides adsorption of the liquid sample. The SPE is coated with immobilized capture antibodies. The wick pad is placed on the SPE and provides absorption of excess reagents maintaining a lateral flow along the strip. The ELFB can be used for rapid and early detection and quantity analysis of biological liquids and wastewater.

Abstract: The electrochemical lateral flow biosensor (ELFB) comprising a novel ELFB strip and electronic detector unit, to which said strip is connected using cable or wirelessly.
