Fungal DNA‐barcoding on a chip: Magnetoresistive biosensors for yeast infection diagnosis
VIEW, Volume 6, Issue 6, December 2025.The development of a fungal pathogen identification chip is herein demonstrated. Hybridization dynamics were tested against 58 species in silico and 4 species on chip. 95% accuracy, 91% sensitivity, 98% specificity and femtomolar limit of detection were achieved. Future perspectives include the integration of sample pre‐treatment modules.
