Inner filter effect (IFE) was previously considered as an error in fluorescence measurement.
In recent years, it has been developed as an important non-irradiation energy conversion …

Upconversion luminescence is an optical process that emits high-energy photons by
absorbing two or more low-energy photons, which is caused by anti-Stokes luminescence …

In this paper, we constructed a fluorescence resonance energy transfer (FRET) system
between amino-functionalized carbon dots (C-dots) and gold nanoparticles (AuNPs). In this …

Carbon dots are admirable fluorescent nanomaterials due to their low cost, high
photostability, excellent biocompatibility, and environmental friendliness. Most conventional …

Reliable and simple detection methods for chemotherapeutic agent contaminants, such as
methotrexate, are required to minimize their possible toxic threat. However, detecting them …

Porous metal-organic frameworks (MOFs) demonstrate great potential for numerous
applications. Although hetero-functional components have been encapsulated within MOF …

Melamine, a nitrogen-containing organic molecule, has received widespread attention as it
had been illegally added in dairy products to increase the content of nitrogen, leading to …

A dichromatic label-free aptasensor was described for sulfadimethoxine (SDM) detection.
Compared with the binding of SDM-aptamer to SDM, the higher affinity of aptamer to cDNA …

Gold nanoparticles (Au NPs) have become one of the most popular materials for sensing of
analytes of interest in the last decade, mainly because of their ease in preparation and …

Semiconductor quantum dots (QDs) are one of the most popular luminescent labels that are
widely used in food and medical analysis. Their unique optical properties establish QDs as …
