By using the arterio-venous shunt, the blood loss can be reduced to a minimum, which is in contrast to most proposed blood flow-through detection systems for small animals that operate only in one way [19,23,33,34].
A novel dual channel in vitro apparatus, derived from a previously described design, has been coupled with dopamine (DA) microsensors for the flow-through detection of DA secreted from PC12 cells.
Furthermore, compared to dead-ended nanohole arrays, suspended nanohole arrays capable of flow-through detection increased the measured SERS signal intensity by 50 times.
When the sample flows through detection line 1, QD1-Ab1-PCT is captured by the fixed 14A2 mAb (Ab3 for short).
After that, when the sample keeps flowing through detection line 2, QD2-Ab2-CRP does not react with the fixed CRP, while extra QD2-Ab2 is captured by the fixed CRP and QD2-Ab2-fixed CRP is formed.
This work shows the possibility of surface-bound aptamer sensing for flow-through analyte detection and provides a useful tool to perform surface fluorescent studies in real-time.
The design of models of a circuit for error detection and correction that is used between the microprocessor and memory fulfil the error-control function, which performs flow-through error detection and correction of data written to, and read from the memory.
Formaldehyde with a final concentration of 25 mM was added to the solution and the mixture was incubated at room temperature for 20 min. To prevent decomposition of methylene-tetrahydropterins the solution was kept under N2 atmosphere and the pH was adjusted to 9. The solution was analyzed by HPLC with UV and flow-through radioactivity detection.
The levels of arsenite in the flow through can then be semiquantitated using the EZ arsenic detection kit provided by Hach chemicals.
The flow through was aided by gravity.
A blood sampling flow-through detector can rely on detection of emitted positrons or single and/or coincidence detection of annihilation photons from blood in the catheter lumen.
