Summary: In this study, a completely greener method was used to convert a natural precursor into high-valued nano-scale material using microwave-assisted conversion. The fluorescent carbon dots prepared, known as long pepper derived carbon dots (LPCDs), were thoroughly characterized and found to exhibit excitation dependent emission behavior. The LPCDs were successfully employed as a fluorescent sensing probe for detecting Sudan I with good selectivity and sensitivity.

Summary: Fluorescence sensing based on Forster Resonance Energy Transfer (FRET) using graphene-based nanomaterials has gained significant interest in various fields. Graphene quantum dots (GQDs), graphene oxide (GO), reduced graphene oxide (rGO), and graphdiyne (GD) can be used as donors/acceptors in FRET-based sensing due to their unique properties. This review discusses the basics of FRET and the role of graphene-based nanomaterials in sensing various analytes, as well as explaining the lower detection ranges. Challenges and future directions for designing nanomaterials with improved sensing performance are also highlighted.

Summary: Adhesion occurs at nanoscale contact between surfaces, which can be evaluated using FRET spectroscopy/microscopy within a range of 1-10 nm. Increased pressure during film pressing leads to higher NSC and adhesion force/energy. FRET microscopy enables visualization of local variations in molecular contact.

Summary: Cell-cleavable protecting groups combined with fluorescent groups can be an effective strategy for constructing biological probes to address issues such as stability, solubility, and cellular uptake. A novel synthesis method was utilized to successfully create a phosphonate compound containing a FRET pair, which can deliver payloads to intracellular receptors. This study demonstrates the potential of bioactivatable phosphonates with FRET pairs in developing probes for monitoring cellular uptake of otherwise charged payloads.

Summary: Biocompatible and luminescent nanostructures synthesized by capping gold-carbon nanoparticles with amino acids were successfully utilized for the quantitative estimation of the drug ranitidine. The method showed a detection limit of 0.174, 0.56, and 0.332 mu M for different amino acid bioconjugates, and was also successful in quantifying ranitidine in spiked serum samples. The study demonstrates the potential of this approach for sensitive and accurate drug quantification.

Summary: Carbon nanomaterials are extensively used in electrochemical sensing composites due to their unique properties, however, their long-term ecological fate remains unknown. Graphene and carbon dots are more biodegradable compared to carbon nanotubes, and design elements such as Coulombic attraction and specific atoms as tethering points are crucial for electrocatalytic performance.
