With deadly diseases like coronavirus, cholera, spreading, it has become vital to discover vaccines or technologies for diagnosing it. Recently scientists have discovered a device that is capable of detecting viruses.
FREMONT, CA: Deploying cutting-edge technologies plays an essential role in the pharmaceutical industry. Recently, researchers at the University of Toronto have come up with a miniaturized chemical heater that is able to heat biological samples precisely during diagnostic tests. Besides, it doesn’t even need electricity or any kind of specialized equipment to operate. This cost-effective technology is based on the exothermic reaction that takes place when lithium comes in contact with water, and the accurate shape of the pill-sized heater governs the heating profile it can generate.
Conducting diagnostic assays for identifying infectious diseases can be hard in remote and low-income domains. Usually, such assays need costly and bulky lab equipment, and low-resource regions might not possess a dependable electricity source. However, sending samples to remote is usually not affordable or practical. Moreover, when it comes to infectious diseases, quickly obtaining the results becomes vital.
One of the problems is that the diagnostic tests need samples and reagents to be heated to particular temperatures at distinct points during such assays. In the laboratory, this is obtained by using electrical heating equipment, like water baths, incubators, or hot plates. For providing an alternative that can be utilized in the field, these researchers have developed a miniaturized chemical heater.
The heater comprises a lithium pill, which is coated in a non-reactive substance. The small gadget can be added to a biological sample and can provide a certain amount of heat obtained by the exothermic reaction that happens when lithium reacts with water. By experimenting with the lithium mold’s shape, the researchers discovered that they could alter the heating profile and duration. They found that a star shape of 8mm in diameter is suitable for accurate heating.
The technology doesn’t need any specialized training or skills and decreases the possibility of human error during assay performance.
