Draw a sensor on the skin to measure blood sugar so easy!

Release date: 2015-03-10

If you think blood glucose must be measured? Then you are faint! There is a magical ink with a special sensor that can help diabetic patients monitor blood sugar and keep abreast of various physical examination indicators. The ink can be written once and read many times. It is a necessary product for measuring poison in the home. The soldiers detect the companion of explosives and nerve agents.

Ink composition

The magic ink came from the University of California, San Diego (UCSD), and the results were published in the February 26 issue of Advanced Healthcare Materials. According to developers, the main components of these inks are glucose oxidase and tyrosinase, which react to blood sugar and phenol. Other components in the ink include: conductive graphite powder used as an electrode; chitosan to help the ink adhere to the surface of the object; xylitol to help stabilize the chemical reaction process of the enzyme; polyethylene glycol, used to polymerize all components .

Can be used like this

How is this ink used? Simply write on the surface of the transparent flexible strip with electrodes to create a blood glucose sensor, drop the blood, and the blood's glucose will react with it. Moreover, the transparent strip can be used repeatedly and wiped clean.

In fact, this is not a big deal. You can even write ink directly on the surface of the skin for testing. The ink can also reduce the tingling sensation of puncturing your fingers.

The biosensor reads the glycemic index through the skin and transmits the result through the Bluetooth device. The ink in one pen can fill 500 blood glucose sensor strips.

Can also be used like this

Ink can also be written on leaves to detect contamination, and after fine-tuning the ingredients, it can react with many other contaminants such as heavy metals or pesticides. There is no limit to the writing surface, on the phone case, on the window.

Future goal

No matter when and where, easy and affordable, easy to use is not expensive. The next step for the developer is to wirelessly connect the handwritten sensor to the monitoring device and analyze the performance under extreme humidity, temperature and lighting conditions.

PCR Reagents

Real time PCR Kit for Monkeypox Virus is used for in vitro qualitative nucleic acid detection of Monkeypox Virus in Human serum, lesion exudate samples and scab specimens. Primer sets and FAM labeled probes are designed for specific detection of Monkeypox Virus, Human RNase P gene extracted concurrently with the test sample provides an internal control to validate nucleic extraction procedure and reagent integrity. Probe targeting human RNase P gene is labeled with VIC.

Intended Use

The test is intended for in vitro qualitative detection of monkeypox virus

(MPXV) antigen in human oropharyngeal swab, whole blood or skin lesion

materials, including lesion exudate, lesion roofs, lesion crusts.

The test is used for monkeypox virus antigen test of monkeypox suspected

populations. Positive result of the antigen test can be used for early triage and

rapid management of suspected populations, but it cannot be used as

diagnosis basis of monkeypox infection. Negative results do not rule out

monkeypox infection and should not be used as the sole basis for treatment or

patient management decisions. Further nucleic acid detection should be

carried out for suspected population whose antigen test result is positive or

negative.

The test is only for professional use, not suitable for family test. The test result

is only for clinical reference and it is recommended to conduct comprehensive

analysis of the disease condition in combination with clinical manifestations of

patients and other laboratory tests.

Test Principle

According to the gold immunochromatographic test principle, the

nitrocellulose membrane is coated with MPXV mAb 2 and goat anti-mouse IgG

antibody, the gold conjugate pad is labeled with MPXV mAb 1. When the

antigen is contained in the sample, the antigen binds with the corresponding

gold labeled monoclonal antibody to form a compound, moving forward under

the chromatography, then combines with the coated antibody in the test line

to form Au-MPXV mAb 1-antigen-MPXV mAb 2 complex to condense into a red

band (Test line, T), indicating a positive result. When the sample does not

contain antigen, complex cannot be formed in the test line, and no red band

appears, indicating a negative result.

No matter whether the sample contains antigen or not, the gold labeled

monoclonal antibody will combine with the coated goat anti-mouse IgG

antibody at the control line to form a Au-MPXV mAb 1-goat anti-mouse IgG

antibody complex and condense into a red band (Control line,C)
