Development of an easy-to-use eco-friendly fluorescent enzyme detection platform

The platform, developed by a research group at the University of Córdoba Department of Analytical Chemistry, has been tested measuring laccase enzyme concentrations in various shampoo samples.

Enzymes are amongst the most widely-used biocatalysts, applicable – thanks to their broad range of properties – in a whole range of fields. There is thus a need for efficient enzyme detection methods.

‘Vortex’ beams for the manipulation of nanoparticles

A lecturer at the University of Córdoba has developed a new method, published in Physical Review Letters, to simplify the process and reduce the cost of manipulating nanometric materials
One millionth of a millimetre: this is the scale at which nanotechnology manipulates matter. Given its many applications, nanotechnology has already had a major impact on recent technological progress; yet its real potential is yet to be discovered, and few scientists doubt that it will lead mankind to a new industrial revolution. A few days ago, University of Córdoba physics lecturer Pedro Rodríguez García published a paper in Physical Review Letters, reporting on the development of a new mechanism which simplifies and reduces the cost of manipulating nanoparticles.

The force behind the accelerated expansion of the universe changes over time

A study published in Nature Astronomy, by an international team including a lecturer at UCO, reveals that the properties characteristic of the mysterious dark energy have varied over the course of history
Hailed by some as a driving force because it causes the accelerating expansion of the universe, dark energy makes up around three quarters of the cosmos, yet little is known about it. The researchers who discovered dark energy six years ago were awarded the Nobel prize, and since then the scientific community has ceaselessly sought to decipher its secrets, which may yield important clues regarding the origin and fate of the cosmos.
