“…[254][255][256] Fluorescence nanohybrids including lanthanide ions can be employed for the detection of sensitizers, such as TC and DPA. This type of target-sensitized new fluorescence emission was discussed in section 3.1.5 [105][106][107][108][109][110][111][112][113][114][115][116] and section 3.2.2, [212][213][214][215][216][217] and thus not emphasized in this part.…”

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.

It is well known that two-dimensional (2D) MXene-derived quantum dots (MQDs) inherit the excellent physicochemical properties of the parental MXenes, as a Chinese proverb says, “Indigo blue is extracted from the indigo plant, but is bluer than the plant it comes from.” Therefore, 0D QDs harvest larger surface-to-volume ratio, outstanding optical properties, and vigorous quantum confinement effect. Currently, MQDs trigger enormous research enthusiasm as an emerging star of functional materials applied to physics, chemistry, biology, energy conversion, and storage. Since the surface properties of small-sized MQDs include the type of surface functional groups, the functionalized surface directly determines their performance. As the Nobel Laureate Wolfgang Pauli says, “God made the bulk, but the surface was invented by the devil,” and it is just on the basis of the abundant surface functional groups, there is lots of space to be thereof excavated from MQDs. We are witnessing such excellence and even more promising to be expected. Nowadays, MQDs have been widely applied to catalysis, whereas the related reviews are rarely reported. Herein, we provide a state-of-the-art overview of MQDs in catalysis over the past five years, ranging from the origin and development of MQDs, synthetic routes of MQDs, and functionalized MQDs to advanced characterization techniques. To explore the diversity of catalytic application and perspectives of MQDs, our review will stimulate more efforts toward the synthesis of optimal MQDs and thereof designing high-performance MQDs-based catalysts.
