Bacteria lies at the root of many infectious and non–infectious diseases. To control and prevent those diseases, there is an urgent need for the rapid and affordable microbial sensing techniques to aid the point-of-care bacterial identification. Here, we report the design and performance of a Multichannel Magnetic Fluorescent Nose (dMFN) for bacteria detection. The system consists of a magnetic nanoparticle conjugated with three different fluorescent proteins (FPs). Upon interacting with bacteria, characteristic levels of the three FPs can be displaced, which are dependent on the binding strength among quaternized magnetic nanoparticles, FPs and bacteria. These characteristic fluorescent responses are bacteria specific, repeatable and can be differentiated by Linear Discriminant Analysis (LDA). The technique is employed for bacterial identity study with a first discriminant of 89.7% within 30 min. We further used dMFN platform for antibiotic screening, the eleven drugs can be distinguished with a first discriminant of 95.2% forE. coliand 97.6% forS. aureu.The generally applicable platform offers a simple tool for the rapid diagnosis and drug screening of pathogens without preprocessing steps.
