The Alphasense OPCN2 / OPCN3 sensors are an optical particle monitor that measures PM , PM and PM 10. Alphasense is certified with ISO 9001:2015. Principle of Operation The Alphasense OPCN2 / OPCN3 sensors use laser beams to detect particles from micron to 17 micron in diameter with 16 bins ( to 40 µm with 24 bins for OPCN3). Count …
20210511· The sensor surface was then quenched by dipping into 10 μg/mL of an irrelevant nanobody for 5 min. Nanobodyloaded sensors were then dipped into premixed solutions of SARSCoV2 RBD and nanobody for 5 min. Nanobodyloaded sensors were also dipped into SARSCoV2 RBD alone to determine the level of SARSCoV2 RBD binding to immobilized …
Alphasense tests the performance of every sensor; results are stored on our database, giving full traceability for all sensors. The unique Automatic Test and Validation (ATAV) system controls initial sensor stabilisation and runs complex tests under computer control. This computerised system also ensures traceability as tested sensors are moved direct to despatch with their …
The strategy usually employed for the de novo design of such engineered IgGs consists on merging fragments of the threedimensional structure of a native IgG, which is immobilized on the biosensor surface, and of an antibody with an exquisite target specificity and affinity. In this work conventional and accelerated classical molecular dynamics (cMD and aMD, respectively) …
20200423· The sensor combines two different effects to detect the virus safely and reliably: an optical and a thermal one. The sensor is based on tiny structures of gold, socalled gold nanoislands, on a glass substrate. Artificially produced DNA sequences that match certain RNA sequences of the SARSCoV2 virus are applied to the nanoislands. The new ...
20210210· 20210210· Sensor M6 for MERSCoV and sensor S1 for SARSCoV2 were tested with several coronaviral RNAs. For the specificity test, 12,000 copies of target RNA were used for RTLAMP.
