New LED with Luminescent Proteins

Estimated reading time: 3 minutes

"The Bio-LEDs are simple to manufacture and their materials are low-cost and biodegradable, meaning that they can easily be recycled and replaced", points out Costa, while also highlighting the high stability of these proteins that have "luminescent properties that remain intact during the months of storage under different environmental conditions of light, temperature and humidity".

In fact, with this technique "we have been able to achieve a sustained use of proteins in optoelectronic devices with an excellent stability for the first time, something that had not happened in the last 50 years. This thus represents a major breakthrough in this field", stresses Pedro B. Coto, another one of the authors who also conducts research at this German university.

Scientists are already working on optimising this new elastic material in order to achieve greater thermal stability and an even longer operating lifetime. They are addressing how to optimise the chemical composition of the polymer matrix in addition to using proteins that are increasingly more resistant to device operating conditions. The goal is to make this new BioLED more accessible on an industrial scale in the not too distant future.
