Researchers at University of Connecticut( Storrs,CT,USA;www.uconn.edu) have developed a revolutionary,biodegradable ultrasound implant,considerably more powerful than earlier models,could improve the treatment of brain cancers.

The ultrasound device implanted directly in the brain can be used repeatedly to allow chemotherapy to permeate the brain and eliminate tumor cells.

An implantable ultrasound device already exists in the market, but it’s made of potentially toxic ceramic materials that require surgical removal post-treatment.

The researchers had earlier built a safe, biodegradable piezoelectric ultrasound brain implant,although it wasn’t as powerful as the traditional ceramic variants.

In their latest research, the team employed a completely new method to create a biodegradable polymer ultrasound that is as powerful as the ceramic models.
