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: In the field of fluorescence-based gas sensing, it is challenging to distinguish molecules with similar chemical properties and slight structural differences. In this study, coassemblies of energy-donor molecule 1 and energy-acceptor molecule 2 with different molar ratios were fabricated. These materials selectively differentiate methanol and ethanol by regulating the distance of exciton migration and can also detect methanol from the mixture vapors of methanol and ethanol.

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: In this study, a molecular probe based on Fo center dot rster resonance energy transfer (FRET) was designed and synthesized for investigating biological phenomena at a single-cell level. The probe utilizes a highly luminescent quantum dot (QD) as a donor and a specific peptide as a linker to a fluorophore or fluorescence quencher as an acceptor. The synthesized probe showed high reaction yield and specificity, and provided longer imaging times of caspases compared to commercial products.

Summary: In the field of polymer structure and dynamics, fluorescence spectroscopy may provide answers to questions that cannot be solved by AI, X-ray, or NMR techniques. FRET theory describes how optically excited fluorophores transfer their energy to an acceptor moiety, depending on the distance between donor and acceptor. However, the dependence on distance distribution and diffusion is described by a partial differential equation (HSE) that can only be solved numerically. Time-resolved measurements and global analysis of extensive data sets are required. The Haas-Steinberg-Jacob equation (HSJE) provides a closed analytical expression and allows for faster and more accurate analysis.

Summary: Deep-red and near-infrared luminogens have been widely used in various fields. However, their complicated structures make synthesis and crystallization difficult, hindering the understanding of the structure-emission relationship. This study successfully achieved multiple deep-red and near-infrared emission ranges through the polymorphism of a simple conjugated luminogen. The packing-dependent emission of the compound helped establish a clear relationship between packing and emission.

Summary: The study investigates the structural and optical properties of polypyrrole-ZnO composites with different amounts of ZnO, finding that the addition of ZnO slightly affects the conjugation of the polymer chain and causes a blue shift in the pi-pi* transition. The research uses a FRET model to theoretically predict the energy transfer efficiency, Forster radius, and separation between donor and acceptor, showing that tuning the ZnO content can adjust the emission properties of the PPy-ZnO composite.

Summary: In this study, efficient amplified spontaneous emission (ASE) of an acceptor was demonstrated in a sophisticated on-chip dynamic droplet Forster resonance energy transfer (FRET) system. The threshold of acceptor ASE was found to depend on the resonance of pump wavelength with the absorption maximum of the donor molecule, while showing no effect on FRET efficiency, indicating that FRET efficiency is independent of the excitation wavelength.
