Some heteropolymers can be designed to spontaneously self-assemble in complex pre-determined knotted structures. In the past, we referred to such designable heteropolymers as “bionic proteins”. Here we present an extensive study on self-knotting bionic proteins. As our everyday experience with ropes teaches us, knots form spontaneously in polymer chains of sufficient length and flexibility have […]

A quantum dot is a nanometric crystalline structure of semiconductor materials. In a quatum dot electrons are confined in a region of space, thus creating a well defined structure of energy levels that depends very much on the size and shape of the quantum dot. This structure resembles that of atoms, that is why sometimes […]
In the transition from a petrol-based society to a one based on bio-renewable resources, the replacement of aromatic chemicals is one of the most challenging issues. Nowadays, around 40% of the bulk chemicals belong to the aromatic category, and a myriad of products are derived from benzene, toluene and xylene. Aromatic molecules are present in […]
When nanoparticles (NPs) get in contact with biological fluids such as blood, proteins present in it will adsorb on the surface of those NPs forming what is known as the protein corona . It is a dynamic process in equilibrium with the surrounding proteins and it may lead to drastic changes in the NPs. The […]
Endohedral fullerenes, also called endofullerenes, are fullerenes that have additional atoms, ions, or clusters enclosed within their inner spheres. The first lanthanum C60 complex was synthesized in 1985 and called La@C60. The @ (at sign) in the name reflects the notion of a small molecule trapped inside a shell. The chemistry of endohedral fullerenes is […]
Common glass, used in windows or bottles, for example, is made by heating a mixture of calcium oxide (lime), sodium carbonate (soda), and silicon (IV) oxide (sand), resulting in a calcium silicate. This silicate is not a crystal but a solid in which atoms are positioned at random and have no long-range ordered pattern. These […]
It is time to round off this trilogy of articles about the importance of basic science nowadays. But first, how does science improve? A research team selects a topic, creates its hypothesis and workflow and, perhaps, tries to publish an article with the findings. This article is read by a new research team, who will […]
Author: Francisco J. Blanco is an Ikerbasque Research Professor at CIC bioGUNE Molecular interactions in cell membranes, particularly lipid-protein interactions in their hydrophobic core, are difficult to analyse and remain poorly characterised despite high relevance in physiological and pathological processes. Structural rearrangements in membranes and embedded proteins, and the way molecular interactions contribute to their […]
“ It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present.— But if (& oh what a big if) we could conceive in some warm little pond with all sorts of ammonia & phosphoric salts, light, heat, electricity etc present […]
Turning simple, individual molecules into complex, interconnected materials is the core of polymer chemistry. There is currently an increasing demand for materials with sophisticated properties such as self-healing and reusable adhesivity. However, achieving polymers with such functionalities generally demands higher structural complexity, synthetic difficulty, and cost. Now, a team of chemists has designed a supramolecular […]
