Di |2022-06-30T01:00:00+02:00Giugno 30th, 2022|Categorie: Coronavirus PubMed|

CONCLUSIONS: This study provides baseline SARS-CoV-2 seroprevalence in Kaduna State, Nigeria, immediately prior to the spread of the Omicron variant. It indicates that in October/November 2021, approximately 56% of the population did not have detectable antibodies, and population subgroups with particularly low seroprevalence remain. It highlights limitations in using PCR-confirmed cases to estimate infection rates. The data will inform public health strategies in Nigeria and other sub-Saharan...

Convection Driven Ultra-Rapid Protein Detection Via Nanobody-Functionalized Organic Electrochemical Transistors

Di |2022-06-30T01:00:00+02:00Giugno 30th, 2022|Categorie: Coronavirus PubMed|

Conventional biosensors rely on the diffusion-dominated transport of the target analyte to the sensor surface. Consequently, they require an incubation step that may take several hours to allow for the capture of analyte molecules by sensor biorecognition sites. This incubation step is a primary cause of long sample-to-result times. Here, we integrate alternating current electrothermal flow (ACET) in an organic electrochemical transistor (OECT)-based sensor to accelerate the device operation....
