Flexibility

The OLED is flexible, which allows it to be molded to the skin, providing more comfort and adhesion.

Biocompatibility

OLED is biocompatible, which means it does not cause skin irritation.

Biodegradability

OLED is biodegradable, which reduces its environmental impact.

Cost reduction

OLED can reduce the cost of manufacturing devices for photodynamic therapies.

The problem-solution approach

Most devices for photodynamic therapies are rigid and non-biocompatible, which can cause discomfort and irritation to the skin. In addition, these devices are generally made of non-biodegradable materials, which increases the environmental impact of these devices.

What is it?

The invention consists of an organic light-emitting diode (OLED) manufactured on an onion membrane. The onion membrane is a flexible, biocompatible and biodegradable material. The OLED can be used in photodynamic therapies for the treatment of various skin diseases, such as skin cancer, psoriasis and acne.

How it works

The OLED works by applying a voltage between two electrodes, an anode and a cathode. Electrons are injected from the cathode into the electroluminescent layer, where they recombine with the holes, emitting light.
