The efficient handling of wastewater pollutants is a must, since they are continuously defiling
limited fresh water resources, seriously affecting the terrestrial, aquatic, and aerial flora and …

Localized surface plasmon resonance (LSPR)-based biosensors have recently garnered
increasing attention due to their potential to allow label-free, portable, low-cost, and real …

In this work, we explored the use of Acacia concinna seeds (shikakai) as a green precursor
for the fabrication of ultra-small fluorescent carbon dots (CDs). The synthesized ultra-small …

The adsorption of DNA onto gold due to affinity interactions is highly desirable for
develo** low-cost, convenient and sensitive biosensors. To date, DNA–gold adsorption …

Food safety is one of the significant global problems that has gained widespread attention
all over the world. Consequently, it is crucial to develop sensitive and reliable detection …

Nanozymes are advanced nanomaterials which mimic natural enzymes by exhibiting
enzyme-like properties. As nanozymes offer better structural stability over their respective …

Colloidal inorganic nanoparticles have wide applications in the detection of analytes and in
biological assays. A large number of these assays rely on the ability of gold nanoparticles …

Herein, a dual-emission metal-organic framework based ratiometric fluorescence
nanoprobe was reported for detecting copper (II) ions. In particular, carbon dots (CDs) and …

G-quadruplex-forming sequence can be formed through a copper (I) ion (Cu+)-catalyzed
