WHAT MAKES A GOOD BIOSENSOR?

• Accuracy/Precision - Our biosensors provide clinically acceptable accuracy and precision over relevant ranges of analyte measurement.
• Sensitivity - Small changes in sensed analyte levels are detectable within clinically meaningful limits.
• Specificity - Uric acid, acetaminophen, and ascorbic acid, the most common interferents in blood, do not effect the accuracy or sensitivity of our biosensors.
• Simplicity - Lower cost, and less likely to be incorrectly made.
• Continuous - Close monitoring of patient analyte levels over time may be critical in some medical situations. Several of our biosensors are designed for such use.

SUB-MICROLITER ASSAYS

A biosensor is a bioanalytical device integrating a biological sensing element with a physicochemical transducer. Biosensors allow biological or biochemical measurements to be made promptly, so that appropriate medical action can be taken. In the case of diabetics, a glucose biosensor can measure the quantity or concentration of glucose in the bloodstream, so that the user can inject insulin as needed.

Kumetrix has designed and tested biosensors in whole blood for glucose, lactate, alcohol, and cholinesterase to name a few. Each sensor uses proprietary technology to maximize the sensitivity towards the analyte over the desired analytical range, while maintaining specificity.

When the biosensor is combined with the Kumetrix silicon microneedle, the resultant microchip becomes the perfect solution for point-of-care, and consumer self-testing. Each miniature disposable has the ability to draw in the small sample volume, perform the required assay, and relay the measurement to the hand-held instrument.
