Nanotechnology has provided endless tools to improve detection systems in the most diverse fields of science. One of those tools is the development of surface enhanced Raman spectroscopy (SERS) that promotes the amplification in 8-10 orders of magnitude of the Raman signals obtained by conventional methods. However, the success of this analytical technique depends on many factors such as the core material of the nanoparticles, their morphology and the adsorption pattern of the analytes on the metal surface, aspects that are not always considered when designing this type of sensors. This work has focus on the effect of these features using a reference molecule such as methylene blue (MB) and two coffee metabolites, trigonelline and chlorogenic acids (CGAs), known as potential quality markers of this agricultural product so important in Peru. Herein, we reported higher Raman signals when u...

Nowadays, cancer is one of the main causes of death worldwide, the cure of which makes it one of the most important targets of modern medicine. Conventional therapies are, either highly invasive (surgery) or little selective (chemo- and radiotherapy), which diminishes the effectiveness of these treatments leading to undesired secondary effects. Nanomaterials, due to its nano size, possess new special features that may provide several advantages for the diagnosis and treatment of this disease in all of its forms. These new systems, have great potential for leading to an early detection of cancer and the design of personalized therapies working only at target zones, improving the results obtained.

Te presentamos un Sudoku poco convencional. En vez de números, este sudoku está compuesto por elementos químicos. Pero no cualquier elemento: el sudoku contiene los nueve elementos más abundantes en el cuerpo humano. El sudoku químico se completa del mismo modo que los sudokus convencionales: deben rellenarse las celdas vacías de modo que no se repita ningún elemento en cada fila ni en cada columna. Diviértete.
