Paper has been present in the world of analytical chemistry for centuries, but it seems that
just a few years back it was rediscovered as a valuable substrate for sensors. We can easily …

Besides the noble physical appearance of gold and silver, their novel chemical properties
attracted the modern technology for various industrial, chemical and biological uses …

Carbon materials have been attracted much attention due to their wide applications in
adsorption, separation, wastewater treatment, electrochemistry.[1] Recently, carbon …

An ultrasensitive split-type fluorescent immunobiosensor has been reported based on a
cascade signal amplification strategy by coupling chemical redox-cycling and Fenton-like …

A highly efficient fluorosensor based on ultrathin graphitic carbon nitride (g-C3N4)
nanosheets for Cu2+ was developed. In the absence of metal ions, the nanosheets exhibit …

A simple and green route was developed for the first time to produce fluorescent graphitic
carbon nitride (Fg-C3N4) by hydrothermal treatment of bulk g-C3N4. The produced Fg …

A simple hydrothermal method was applied to prepare carbon nanodots (C dots) from o-
phenylenediamine (OPD). The C dots exhibit photoluminescence at 567 nm when excited at …

In this study, a novel N and S co-doped carbon dots (N, S-CDs) had been prepared with
content of N and S as high as 17% and 19%, respectively. Combining electrochemical …

A simple ratiometric fluorescent and colorimetric dual-signal sensing system for Cu 2+ and
pyrophosphate ion (PPi) detection is established based on N-doped carbon dots (N-CDs) …

A colorimetric and fluorometric turn-on probe L,(E)-1-((pyridin-4-yl) methylene)
thiosemicarbazide has been synthesized and characterized by X-ray single crystal analysis …
