When we consider the concepts metal and catalysis, we tend to assume quite matter-of-factly that the metal will be the catalyst. This assumption is based on the fact that metals can be found in reactions where they act as catalysts or co-catalysts in the form of coordination and organometallic compounds, nano-sized or bulk materials and […]

There are instances in which you would intentionally deliver nanoparticles to animals (humans included). Contrast agents for medical diagnosis or therapeutic ones for medical treatments are two examples. It is also the case with plants, as some fertilizers take the form of nanoparticles. Unintentional exposure of animals or plants to nanoparticles is also possible: environmental […]

Inorganic and organic light-emitting diodes (ILEDs and OLEDs, respectively) are quickly replacing incandescent light bulbs and compact fluorescent lamps. The reasons for the success are easy to understand. For instance, ILEDs’ performance has met the market requirements for in-/out-door applications with single-point sources. However, ILEDs cannot be considered a sustainable solution as of today. One […]

Microscopy is a leading technology in biological research. Today, a typical microscopy session may generate hundreds to thousands of images, generally requiring computational analysis to extract meaningful results. But a simple analysis is not enough any more. Over the last few years, deep learning (DL) has increasingly become one of the gold standards for high-performance […]

A new fluorescent bicolour indicator, an organic molecule, could help detect the daughter atom of a neutrinoless double beta decay. If this is achieved, there would be an explanation to the matter-anti matter asymmetry in the universe. Experiments performed in 1909 by Geiger and Marsden, also called Rutherford gold foil experiment because Rutherford was their […]

A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. As the catalyst itself takes part in the reaction it may undergo a physical change. Metal complexes are typically regarded as catalysts that convert organic substrates into more valuable compounds; however, to date, catalytic transformations […]

Proteins can perform a huge number of biological functions with amazing efficiency. In order to achieve these different functions, proteins rely on the precise 3D arrangement of functional groups which are referred to as the protein fold. Some of these functions include acting as a catalyst in biochemical reactions; in these cases proteins are called […]

We all know that the main role of DNA is the storage of genomic information leading to the biosynthesis of proteins via diverse forms of RNA. In turn, proteins play multiple roles in living systems, catalysis being among the most important ones. These are the standard functions that we may find in any general chemistry […]

The combination of catalysis and bioorthogonality promises have an impact on drug discovery and bioimaging. Bioorthogonality, a term coined by Carolyn R. Bertozzi in 2003, refers to any chemical reaction that can occur inside of living systems without interfering with native biochemical processes. Hence, catalytic turnover can boost the efficiency of bioorthogonal chemical reactions, unveiling […]
