In this paper, an amplified fluorescence polarization (FP) aptasensor based on magnetic nanoparticles @polydopamine (MNP@PDA) was innovatively developed for sensitive detection of recombinant human erythropoietin-alpha(rHuEPO-α). The amplified FP signal was due to the large mass of protein and MNP@PDA. And this assay can be utilized for target separation or recycling based on the magnetic property...
Electrochemical biosensors have shown great promise in the development of rapid methods for the detection of foodborne pathogens and have been intensively studied over the past two decades. The scope of this review is to summarize the advancements made in the development of electrochemical biosensors for the rapid detection of one of the most common foodborne pathogens, Escherichia coli O157:H7. The...
Foodborne pathogens have continuously been a serious food safety issue and there is a growing demand for a rapid and sensitive method to screen the pathogens for on-line or in-field applications. Therefore, an impedimetric immunosensor based on the use of magnetic beads (MBs) for separation and a screen-printed interdigitated microelectrode (SP-IDME) for measurement was studied for the rapid detection...
