“…The total doping content (especially nitrogen) was higher as compared to previous reports of CQDs synthesized using different plant sources. [42][43][44] The synergic effect of doping, composition, and functional groups could be their utility in various elds. Herein, we checked the antimicrobial and antioxidant activities of the developed CQDs.…”

“…The high-resolution core-level spectrum of O 1s shown in Figure 1J also confirmed the presence of different oxygen-containing functional groups of the citrate, including C−O (530.78 eV), 54 CO (531.88 eV), 55 and O−CO (535.58 eV). 56 In addition, the Ag 3d core-level spectrum shown in Figure 1K can be decomposed into Ag 3d 5/2 (367.48 and 368.38 eV) and Ag 3d 3/2 (373.58 and 374.48 eV). 57,58 The XRD profile of AgNPs exhibited a number of Bragg reflection values (38.16, 44.38, 64.48, and 77.56°) at the 2θ angle, which corresponded respectively to (111), ( 200), (220), and (311) sets of AgNP lattice planes 59 (Figure 1L, note that the peaks marked with an asterisk at 33.02, 56.38, and 69.16°correspond to the SiO 2 substrate 60,61 ).…”

Plasmonic materials have been widely used in chemo/biosensing and biomedicine. However, little attention has been paid to the application of plasmonic materials in terms of the transition from molecular sensing to molecular informatization. Herein, we demonstrated that silver nanoparticles (AgNPs) prepared through facile and rapid microwave heating have multimode colorimetric sensing capabilities to different metal ions (Cr 3+ , Hg 2+ , and Ni 2+ ), which can be further transformed into interesting and powerful molecular information technology (massively parallel molecular logic computing and molecular information protection). The prepared AgNPs can quantitatively and sensitively detect Cr 3+ and Hg 2+ in actual water samples. The AgNPs' multimode-guided multianalyte sensing processing was further investigated to construct a series of basic logic gates and advanced cascaded logic circuits by considering the analytes as the inputs and the colorimetric signals (like color, absorbance, wavelength shift) as the outputs. Moreover, the selective responses and molecular logic computing ability of AgNPs were also utilized to develop molecular cryptosteganography for encrypting and hiding some specific information, which proves that the molecular world and the information world are interconnected and use each other. This research not only opens the door for the transition from molecular sensing to molecular informatization but also provides an excellent opportunity for the construction of the "metaverse" of the molecular world.

“…The fluorometric assay was also utilized for the detection of aspartic acid and glutamic acid, based on their isoelectric points. In 2020, Zhong et al [ 120 ] produced blood compatible N,S-CQDs by hydrothermal synthesis from m -phenylenediamine and tobias acid. Characterization studies revealed a QY of 37.2%.…”

Carbon quantum dots (CQDs) have started to emerge as candidates for application in cell imaging, biosensing, and targeted drug delivery, amongst other research fields, due to their unique properties. Those applications are possible as the CQDs exhibit tunable fluorescence, biocompatibility, and a versatile surface. This review aims to summarize the recent development in the field of CQDs research, namely the latest synthesis progress concerning materials/methods, surface modifications, characterization methods, and purification techniques. Furthermore, this work will systematically explore the several applications CQDs have been subjected to, such as bioimaging, fluorescence sensing, and cancer/gene therapy. Finally, we will briefly discuss in the concluding section the present and future challenges, as well as future perspectives and views regarding the emerging paradigm that is the CQDs research field.
