Amine functionalized carbon quantum dots from paper precursors for selective binding and fluorescent labelling applications

In vitro Analytical Techniques as Screening Tools to investigate the Metal chelate‐DNA interactions

“…The purity of DNA can also be found by calculating the absorbance ratios (A260/A280 and A260/A230). Variations in the media's pH or ionic strength result in a noticeable change in the parameters such as the absorption maximum and the molar absorptivity value [52,53] …”

“…To develop a potential anticancer drug, the cytotoxicity and selectivity of different transition metal complexes were considered, and it was found that they play a major role in influencing the design of the drug. The interactions of diverse transition metal ion complexes with these small biomolecules such as amino acids, peptides, and nucleotides and their interactions with DNA are taken into consideration while studying its potential anticancer activity [53] . Redox characteristics, electrophilicity, nucleophilic reactivity, and kinetic lability of these complexes are some of the factors responsible for establishing an interaction between the DNA and the complexes [149–152] …”

“…DNA cleavage is a process that breaks one of the covalent sugar‐phosphate links between the nucleotides resulting in the loss of its biological activity. Enzymatic, chemical, or radiation catalyzes this reaction [53] . The ability of the metal complexes to break the DNA was determined using gel electrophoresis.…”

Carbon Dots from Natural Sources for Biomedical Applications

“…The n‐π* (300–330 nm) and π–π* (320–270 nm) transitions are characteristic of the CDs. [ 262 ] The excitation wavelength dependence of the emissions of CDs is recorded along with the fluorescence emissions of CDs to explain the effect of size distribution and aggregation tendency of carbon dots. [ 262 ]…”

Microwave-assisted rapid synthesis of nitrogen-enriched amphibious carbon quantum dots for sensitive detection of ROS and multiple other applications

“…These nanomaterials are being increasingly employed in renewable energy harvesting and storage, bioimaging, chemical and biomaterial sensing, catalysis, anticounterfeit printing and nanomedicine design. [1][2][3][4] Although these carbonaceous nanodots are mentioned under the broad category of 'nanoparticles', their diameters are mostly below 10 nm. These graphene family quasi-spherical fluorescent nanomaterials are considered zero-dimensional (0D) nanoparticles compared to the spherical, tubular or sheet structures.…”
