“…Antibiotic and drug sensing requires the provision of sensors capable of detecting specific antibiotics or a particular drug with high sensitivity, while eliminating interfering substances in body fluids is of great importance for accurate detection. 198,199 Vitamins, amino acids, and peptides pose challenges due to their structural diversity and low molecular weight, which require the development of visual sensors. Food spoilage indicators require sensors capable of detecting biogenic amines, at trace levels with high selectivity, which are essential for ensuring food safety.…”

“…Many neutral molecules have been the target for sensor design. Among these molecules, we can mention, for instance, biogenic amines [78], chemical warfare agents [79][80][81], illicit drugs [82,83], and pharmaceutical drugs [84][85][86][87]. In addition, recently, considerable attention has also been given to amino acids.…”

Optical detection devices have become an analytical tool of interest in diverse fields of science. The search for methods to identify and quantify different compounds has transposed this curiosity into a necessity, since some constituents threaten the safety of life in all its forms. In this context, 30 years ago, Prof. Prasanna de Silva presented the idea of sensors as Molecular Logic Gates (MLGs): a molecule that performs a logical operation based on one or more inputs (analytes) resulting in an output (optical modification such as fluorescence or absorption). In this review, we explore the implementation of MLGs based on the interference of a second input (second analyte) in suppressing or even blocking a first input (first analyte), often resulting in INHIBIT-type gates. This approach is interesting because it is not related to attached detecting groups in the MLG but to the relation between the first and the second input. In this sense, flexible and versatile MLGs can be straightforwardly designed based on input selection. To illustrate these cases, we selected examples seeking to diversify the inputs (first analytes and interfering analytes), outputs (turn on, turn off), optical response (fluorescent/colorimetric), and applicability of these MLGs.

MXene quantum dots (MXene QDs) are considered an excellent emerging zero-dimensional nanomaterial in recent times due to their excellent photophysical and chemical properties. Excitation-dependent emission properties, biocompatibility, photostability, and dispersion stability of these QDs undoubtedly prove to be active potential candidates for environmental and biomedical applications. This review paper focuses on the progress of MXene quantum dots synthesis via various approaches, their sensing toward various analytes, and bioimaging applications from the year 2017 to date. Varied types of approaches have been summarized to prepare high-quality dispersive MXene QDs with a good fluorescence quantum yield. Their formation mechanism via fragmentation and different characterizations has been well represented. The detailed analysis behind fluorescence from QDs has been also discussed. Next, selective recognition of various analytes, including metal ions, proteins, enzymes, drug molecules, and reactive oxygen species via the fluorescence modulation of the quantum dots, has been detailed and documented along with an in-depth mechanism. Their bioimaging application has also been represented. Finally, challenges and perspectives have been enlightened at the end.
