By analyzing data from NASA's Chandra X-ray Observatory, Dutch astronomers have investigated a young, oxygen-rich supernova ...

Hepatocellular carcinoma (HCC) represents a major global health burden due to its high recurrence and mortality rates. For patients with advanced HCC and compromised liver function, Pharmacotherapy ...

The incorporation of upconversion luminescence (UCL) materials into various plasmonic structures promotes light–matter interactions in nanophotonic systems. It has been experimentally demonstrated ...

Elucidation of upconversion nanoparticles (UCNPs) that can be excited by near-infrared (NIR) light is an interesting topic in the field of photodynamic therapy (PDT). However, the PDT efficiency of ...

A research team led by Hans Ågren, professor in theoretical chemistry at KTH Royal Institute of Technology, has developed a film that can be applied on top of ordinary solar cells, which would enable ...

Engineering of reconfigurable nanoparticle assemblies enabled the practical realization of multiplexed detection, monitoring, and in vivo imaging of miRNA in live cells and animals, which was ...

A novel core–shell structure based on upconversion fluorescent nanoparticles (UCNPs) and dopamine–melanin has been developed for evaluation of the antioxidant capacity of biological fluids. In this ...

There is a great need to develop multifunctional nanoparticles (MFNPs) for cancer biomarker-based detection and highly selective therapeutic treatment simultaneously. Here we describe a facile ...

Photostability and non-blinking behavior of a single UCNP. (A) The time trace of emission intensity from a single UCNP under continuous laser illumination for more than 1 h, suggesting the durable ...
