“…There are several reports that have constructed AND logic operation through the detection of different metal ions, such as Cr 6+ [ 37 ], Hg 2+ [ 38 ], Cu 2+ [ 39 ], and Fe 3+ [ 40 ]. Apart from AND, other logic operations such as the INHIBIT function were also fabricated through sensing of various metal ions through different amino acid derivatized CDs [ 41 ], histidine [ 42 ], Cu 2+ , H 2 S [ 43 ], arginine, and acetaminophen [ 44 ]. Other researchers developed IMPLICATION logic operations using the sensing ability of CDs for Hg (II) and cysteine [ 45 ], AA [ 46 ], Fe 3+ [ 47 ], Hg 2+ , and biothiols [ 48 ], Hg(II), and glutathione [ 49 ].…”

Carbon dots (CDs)-based logic gates are smart nanoprobes that can respond to various analytes such as metal cations, anions, amino acids, pesticides, antioxidants, etc. Most of these logic gates are based on fluorescence techniques because they are inexpensive, give an instant response, and highly sensitive. Computations based on molecular logic can lead to advancement in modern science. This review focuses on different logic functions based on the sensing abilities of CDs and their synthesis. We also discuss the sensing mechanism of these logic gates and bring different types of possible logic operations. This review envisions that CDs-based logic gates have a promising future in computing nanodevices. In addition, we cover the advancement in CDs-based logic gates with the focus of understanding the fundamentals of how CDs have the potential for performing various logic functions depending upon their different categories.

The use of fluorescent probes in a multitude of applications is still an expanding field. This review covers the recent progress made in small molecular, spirocyclic xanthene-based probes containing different heteroatoms (e.g., oxygen, silicon, carbon) in position 10′. After a short introduction, we will focus on applications like the interaction of probes with enzymes and targeted labeling of organelles and proteins, detection of small molecules, as well as their use in therapeutics or diagnostics and super-resolution microscopy. Furthermore, the last part will summarize recent advances in the synthesis and understanding of their structure–behavior relationship including novel computational approaches.

“…[13] Amino acids, as the basic components of proteins, [14] play a vital role in most aspects of the body, such as participating in metabolism, maintaining the normal redox environment of cells, and the balance of the central nervous system of the human body. [15,16] In the detection of amino acids, Fourier transform infrared spectroscopy (FT-IR), [17] high performance liquid chromatography, [18] capillary electrophoresis [19] mass spectrometry, [20] have shown excellent results. Similarly, we should also develop a fast and efficient platform to detect amino acid molecules, which not only can be utilized to understand the metabolic processes in the human body, but can also provide effective information for medical treatment.…”

In this work, based on the conjugated structure of the naphthalene ring system, four stable Cd-NDI complexes {[Cd-o-H 2 BDC = phthalic acid; m-H 2 BDC = iso-phthalic acid; p-H 2 BDC = p-phthalic acid; H 3 TIBTC = 2,4,6-triiodo-1,3,5-benzene tricarboxylic acid) are designed and synthesized. The four Cd-NDI complexes have good luminescence properties, and complexes 1-3 can selectively detect Cr 2 O 7 2À and L-Arginine in water. Complex 1 has the best ability to detect Cr 2 O 7 2À with a limit of detection (LOD) of 2.32 μM; complex 3 can be employed for the detection of Larginine with a LOD of 2.25 μM. Complex 1-3 may be useful for monitoring water quality and treating wastewater as a good fluorescence sensor. In addition, based on the specific detection species of C=N bonds by complexes 1-3, we take complex 3 as an example to conduct preliminary studies monitoring a Schiff base reaction in situ with fluorescence quenching. This provides a new method for monitoring organic reactions. Besides, we also have explored the ability of complex 4 to detect pnitroaniline. The results show that the complex 4 could selectively detect p-nitroaniline with a LOD of 5.12 μM.
