For faster healing, try smart bandage

According to a new research, studies have found that smart bandage could expedite healing.

 The bandage consists of electrically conductive fibres coated in a gel that can be individually loaded with infection-fighting antibiotics, tissue-regenerating growth factors, painkillers or other medications.

A microcontroller no larger than a postage stamp, which could be triggered by a smartphone or other wireless device, sends small amounts of voltage through a chosen fibre.

A single bandage could accommodate multiple medications tailored to a specific type of wound, the researchers said, while offering the ability to precisely control the dose and delivery schedule of those medications.

The combination of customization and control could substantially improve or accelerate the healing process, said Ali Tamayol, assistant professor of mechanical and materials engineering at Nebraska.

“This is the first bandage that is capable of dose-dependent drug release,” Tamayol said. “You can release multiple drugs with different release profiles. That’s a big advantage in comparison with other systems. What we did here was come up with a strategy for building a bandage from the bottom up.

“This is a platform that can be applied to many different areas of biomedical engineering and medicine,” he added.

Those wounded in combat might also benefit from the bandage’s versatility and customizability, Tamayol said, whether to stimulate faster healing of bullet and shrapnel wounds or prevent the onset of infection in remote environments.

“Soldiers on the battlefield may be suffering from a number of different injuries or infections,” he said. “They might be dealing with a number of different pathogens. Imagine that you have a variable patch that has antidotes or drugs targeted toward specific hazards in the environment.”

 

In the meantime, he said, the researchers are also working to incorporate thread-based sensors that can measure glucose, pH and other health-related indicators of skin tissue.

Integrating that capability would allow the team to create a bandage that could autonomously deliver proper treatments.

Even though Karnataka recorded the lowest number of Covid deaths in April since the virus struck first in 2020, the state is recording a rise in the positivity rate (1.50 per cent). Five people died from the Covid infections in April as per the statistics released by the state health department. In March, the positivity rate stood around 0.53 per cent. In the first week of April it came down to 0.38 per cent, second week registered 0.56 per cent, third week it rose to 0.79 per cent and by end of April the Covid positivity rate touched 1.19 per cent.

on an average 500 persons used to succumb everyday in the peak of Covid infection, as per the data. Health experts said that the mutated Coronavirus is losing its fierce characteristics as vaccination, better treatment facilities and awareness among the people have contributed to the lesser number of Covid deaths.

During the 4th and 6th of April two deaths were reported in Bengaluru, one in Gadag district on April 8, two deaths were reported from Belagavi and Vijayapura on April 30. The first Covid case was reported in the state in March 2020 and three Covid deaths were recorded in the month. In the following month 21 people became victims to the deadly virus, and May 2020 recorded 22 deaths. The death toll recorded everyday after May crossed three digits. However, the third wave, which started in January 2
