An approach to enhance self-compensation capability in paper-based devices for chemical sensing.

摘要: This paper describes a simple design for increasing the tolerance of reagent dislocation on paper-based platform using combination wax-treated and vortex mixer. To date, massive budgetary funds are required in biotechnological industry to develop new applications; large part that cost is attributable screening specific chemical compounds. Here, we propose liquid-handling robot automatically deposit selected reagents platform. We also present preliminary concept approach developing placing device with inexpensive features. A defect inaccuracy was observed between droplet location test well after viewing performance our Because error resulting from robotic placement, decided apply an external, rotational force following placement order compensate distance dislocation. Note, largest determined by examining results altering applied volume, but not concentration, volumes 5 µL 30 series experiments. As result these experiments, positively affected increase volume. colorimetric assay nitrite detection performed confirm feasibility this method. work, believe, can minimize compound industry.
