Photon upconversion involves a series of non-linear optical processes where the sequential absorption of two or more photons leads to the emission of a single photon with energy greater than the sum ...

Photothermal therapy (PTT) uses light to target cancer by local heating of a light-absorbing medium proximate to or internalized by cells and malignant tumors. It uses a photosensitizer molecule that, ...

While Raman spectroscopy has been hugely successful in a number of domains of chemistry and materials science, 1-3 one of the main challenges with performing Raman measurements is the inherently weak ...

(Upper panel) Experimental scheme. When a chiral gold nanoparticle is illuminated with near-infrared linearly polarized femtosecond light pulses, circularly polarized luminescence is observed in the ...

A crucial element in both the synthesis and functionality of nanoparticles involves the attachment of ligands. 6 The appropriate choice of ligands can enhance the solubility of nanoparticles or affect ...

Cancer is one of humanity’s most formidable health challenges, claiming nearly 10 million lives each year, with global cases projected to rise to Cancer is one of humanity’s most formidable health ...
