As virus outbreaks become normalized, we urgently need to develop rapid, sensitive, and cost-effective detection methods. Only through joint efforts of testing and tracking can virus outbreaks be effectively controlled before they become epidemics.

The new epidemic virus is raging

In the past decade, the Zika virus and Ebola virus have been widely prevalent. Recently, a new type of epidemic virus has emerged（SARS-CoV-2）Moreover, the virus has spread to various parts of the world in just a few months.

Traditional detection methods have encountered bottlenecks in controlling the spread of infectious diseases. The high cost limits the affordability and feasibility of testing for the general population. Especially for poorer areas, complex analysis processes require professional personnel, which is not applicable to all regions.

Use screen printed electrodes for detection

Instant medical testing using screen printed electrodes can quickly and widely detect viral outbreaks in populations at low cost, without the need for skilled analysts or complex measuring equipment. Due toSPEsIt is customizable, so it can be modified and manufactured to meet the needs of various research groups.

Quick and instant medical testing

Screen printing electrode（SPEs）Rapid and diverse infectious disease testing can be conducted on populations without the need for professional technicians or complex equipment. Recent studies have shown that the use ofSPEsThe possibility of conducting rapid and immediate medical testing.

Advantages of Electrochemical Testing

−Quick testing

The rapid testing capability of electrochemical biosensors is one of their significant advantages. Results can be obtained in just a few minutes, not hours or days. Waiting for a few days may lead to further virus transmission within the region, and early prevention is crucial to prevent the spread of the disease.

−Low detection limit

Specific electrochemical detection techniques, such as voltammetry or amperometry, can already detect low concentrations of analytes. The high adsorption capacity of carbon based working electrodes with certain recognition elements attached plays a key role in improving sensitivity.

−Easy to use

Measurement equipment andSPEsThe size of the electrodes is very compact, allowing you to experience excellent portability. Even in remote areas, rapid and accurate virus testing can be conducted in any situation without the need for large laboratory facilities. Simply drop a small amount of sample onto the electrode and insert it into the measuring device to obtain results within minutes.

−Economic low consumption

Low cost is a major advantage of using screen printed electrodes for virological research. eachSPEAll are disposable to ensure the repeatability of testing for each sample.SPEsThe price of its measuring equipment is very economical, which is more attractive to economically average areas. In addition, testing does not require laboratories and trained laboratory analysts.

−customizable
