Minimalist biostructures designed to create nanomaterials

Researchers from the IBB-UAB and from the ICMAB-CSIC have obtained four molecules of only seven amino acids with the ability to self-assemble, which enables a fast and non expensive process to obtain nanomaterials for biomedical and nanotechnological purposes. They have used them to create one of the most resistant bionanomaterials described until now.

Organic and miniaturized photodetectors that absorb light beyond the visible range

They detect light below its absorption band and with a high efficiency. The presented devices demonstrate a wide spectroscopic photodetection and compactness of the device, making them much more portable and suitable for integrated electronics applications. The study was carried out by ICMAB researchers in collaboration with researchers from Dresden (Germany) and from Beijing (China).

Iridescent photonic cellulose, which mimics the structural color of insects, with optical applications

A study developed at the ICMAB-CSIC and published in Nature Photonics describes the technique to provide structural coloration on a cellulose derivative through its nanostructuration. The colors obtained do not depend on pigments but on nanostructures that interact differently with the incident light. Applications include ecofriendly production of color in packaging systems or decorative paper, anti-counterfeiting technology, or biocompatible, biodegradable, washable and edible and low cost detectors, sensors or labels.

Superabsorbers nanomaterials that trap sunlight

ICMAB researchers have designed ultrathin materials that maximize the absorption of light in a large range of the solar spectrum. The followed strategy is low cost and fully scalable. The obtained superabsorbers materials have many potential applications, especially in the field of photovoltaic energy and photodetection.
