Heavy metal ions, which are over-emitted from industrial production, pose a major threat to
the ecological environment and human beings. Among the present detection technologies …

In spite of the long-term awareness of the conversion of light to heat even in materials with
low absorption coefficient via the photothermal effect and consequent usage of the effect to …

Toxic metals and metalloids pollution is a major ecological and human health issue, yet
classical detection methods are limited. Here we review surface-enhanced Raman …

Background The thermally coupled energy states that contribute to the upconversion
luminescence of rare earth element-doped nanoparticles have been the subject of intense …

Droplet assay platforms have emerged as a significant methodology, providing distinct
advantages such as sample compartmentalization, high throughput, and minimal analyte …

The routinely employed ensemble and individual luminescent nanoparticles play pivotal
