Editorial on the Research Topic Rapid Detection of Fungi, Microbial, and Viral Pathogens Based on Emerging Biosensing Technology Fungi, microbial, and viral pathogens have been constantly posing serious threats to human society over the past centuries. Notorious examples in history that claimed millions of innocent lives, like the Plague of Justinian in 541 AD, the Black Death in 1347, the Italian Plague in 1629-1631, the Great Plague of London during the 16th and 17th centuries, the Spanish Flu in 1918, and recent COVID-19 pandemic that started in 2019, all resulted from either bacterium or virus outbreaks. However, the adverse situation had never been overturned until the second industrial resolution in the late 19th century and early 20th century that brought up immense science advances. The rapidly progressive technology, for the first, imparted humans some powerful weapons to win the unconventional war on the invisible battlefields. The comprehensive understanding of microbiology renders the science behind the microbes and leads researchers to decipher more traits about their weakness and strength. In the 1990s, the emerging microfabrication became the first cornerstone to bring the lab-on-a-chip style biosensing technology from theory to reality. The central concept is to seek early medical treatments by early diagnosis. Recently, numerous research efforts have been made in mechanical, optical, electrical, biochemical aspects, making the sensing technology more accurate, sensitive, specific, compact, cost-effective, and rapid than their past counterparts. Electrochemistry has been long adopted as a label-free means in most biochemical detections (CesewskiB and Johnson, 2020). Their simple integration
