Frances-Soriano L, Bellezza D, Ferrera-Gonzalez J, Gonzalez-Bejar M, Perez-Prieto J
Nanoscale Adv . 2024 Oct; PMID: 39355838
Upconversion nanohybrids (UCNHs) consisting of rose bengal (RB) and upconversion nanoparticles (UCNPs) are able to promote terpinene oxidation upon near-infrared irradiation. The photophysical events occurring upon NIR-irradiation of the UCNH...

Frances-Soriano L, Ferrera-Gonzalez J, Gonzalez-Bejar M, Perez-Prieto J
Anal Bioanal Chem . 2022 Mar; 414(15):4291-4310. PMID: 35312819
Near-infrared optical imaging offers some advantages over conventional imaging, such as deeper tissue penetration, low or no autofluorescence, and reduced tissue scattering. Lanthanide-doped nanoparticles (LnNPs) have become a trend in...

Ferrera-Gonzalez J, Frances-Soriano L, Galiana-Rosello C, Gonzalez-Garcia J, Gonzalez-Bejar M, Frohlich E, et al.
Biomedicines . 2021 Oct; 9(10). PMID: 34680536
Nanoparticles for medical use should be non-cytotoxic and free of bacterial contamination. Upconversion nanoparticles (UCNPs) coated with cucurbit[7]uril (CB[7]) made by combining UCNPs free of oleic acid, here termed bare...
