Benzimidazole-based ratiometric fluorescent receptor exhibiting molecular logic gate for Cu2+ and Fe3+

Oligonucleotide‐Based Luminescent Detection of Metal Ions

“…In this context, molecular logic gates responding to metal-ion inputs have received much attention due to the importance of metals in biology and in the environment, and many such logic gates based on small molecules have been reported. [135][136][137][138][139][140][141][142] However, technical issues such as solubility and stability in aqueous solutions limit the potential integration of organic molecules into biologically relevant systems.…”

A selective colorimetric chemosensor for Fe3+

“…Iron ion deficiency leads to anemia, liver and kidney damages, diabetes, and heart disease, therefore the detection of iron ions is crucial to the control of its concentration level in the biosphere and its direct impact on human health. Much research has been directed toward developing sensitive and selective sensors for Fe 3+ or Fe 2+ , however many reported Fe 3+ sensors suffer from interference by Fe 2+ . In addition, the fluorescence detection of Fe 3+ is marred by quenching, due to its paramagnetic nature, therefore the development of more sensitive, real‐time and inexpensive methods for monitoring Fe 3+ is desirable.…”

Synthesis, chemosensing properties and logic behaviour of a novel ratiometric 1,8-naphthalimide probe based on ICT and PET

“…The amalgamation of PET and ICT pathways has provided examples of multilevel logic systems with multiple logic functions, including arithmetic operations by modulation of the fluorescence output [44][45][46][47][48]. The molecules capable of carrying out a variety of sensing functions simultaneously, and to compute a composite result autonomously, have great potential for real-life applications such as object coding and imaging, intelligent materials, drug delivery and activation, diagnostics or actuation [49][50][51][52][53][54][55][56][57][58][59].…”
