Abstract [n] Helicenes are polycyclic aromatic molecules in which n ortho‐condensed
benzene or other aromatic rings give rise to helical chiral and highly conjugated structures …

Although transition metals constitute less than 0.1% of the total mass within a human body,
they have a substantial impact on fundamental biological processes across all kingdoms of …

Cu 2+ is an essential trace element for the organism, but its excess can also cause
irreversible damage to the organism. As such, a “Turn-Off” fluorescent probe DPAP for the …

A new fluorescence probe based on [5] helicene derivative (MT) was designed and
synthesized. The chemical structure of the probe was fully characterized by NMR, mass …

With the development of society, the modern environment has put forward higher
requirements for analysis and detection. This work proposes a new strategy for the …

A near-infrared (NIR) colorimetric fluorescence sensor, Cy7C3, based on heptamethine
cyanine dye was synthesized for determining the presence of Cu 2+ ions. The sensor …

Mercury pollution and its toxicity pose a grave threat to health. Therefore, developing new
approaches for detecting mercury ions (Hg 2+) in environmental and biological samples is …

A new Hg 2+ colorimetric and fluorescent sensor (NT) was synthesized. The chemical
structure of the sensor consists of 7-nitrobenzo-2-oxa-1, 3-diazolyl (NBD) fluorophore and …

Over the past years, lung cancer has been one of the vital cancer-related mortalities
worldwide and has inevitably exhibited the highest death rate with the subsequent need for …

Biological thiols including homocysteine (Hcy), cysteine (Cys), hydrogen sulfide (H 2 S) and
glutathione (GSH) play crucial roles in various pathological and physiological processes …
