Although there are already a variety of implants that deliver drugs inside the body, most cannot be controlled outside the body, or require surgery to replace them.

However, a new implant that uses light has avoided both problems, according to New Atlas, citing the Proceedings of the National Academy of Sciences.

Overcome previous negatives

The research reported that the majority of existing implants for drug delivery usually take one of two forms, one of which disintegrates harmlessly over time so no surgical procedure is required to remove it.

The other type can be activated remotely via radio signals or other means, but it contains electronic components that are not biodegradable, which means that the patient may have to have surgery to remove it.

The best features

In new research, an experimental device was developed by a team of scientists at Shirley Ryan AbilityLab in Chicago and Northwestern University, and combines the best features of both types of implants.

The current prototype is made of magnesium, molybdenum and a polyanhydride polymer, all of which are biodegradable.

It also contains 3 drug-filled tanks, each built into a biodegradable battery.

The electrical resistance of the phototransistor decreases when it is exposed to a certain wavelength of light, causing the battery to short circuit, allowing the drug to travel to surrounding tissues.

separate doses

Because each tank’s phototransistor is sensitive to a different wavelength of light, the implant is able to release the drugs three separate times each time using a different type of light.

In laboratory tests conducted to date, the innovative implant has been successfully used to release the analgesic lidocaine in mice.

The light source consists of three external LEDs of different colours, which shine through the animal skin and underlying tissue at the implant site.

It is noteworthy that Dr. Colin Franz, a researcher in Shirley Ryan’s laboratory, who led the study, had confirmed that this technology represents a major achievement in addressing the shortcomings of current topical drug delivery systems.

He added that this might have important and comprehensive effects for many topical therapeutic purposes that the medical staff needs to use at a specific point only in the body, so as not to cause damage or collateral damage to other organs in the body.
