ATTO 565, a Rhodamine-type dye, has garnered significant attention due to its remarkable optical properties, such as a high fluorescence quantum yield, and the fact that it is a relatively stable structure and has low biotoxicity. ATTO 565 has found extensive applications in combination with microscopy technology. In this review, the chemical and optical properties of ATTO 565 are introduced, along with the principles behind them. The functionality of ATTO 565 in confocal microscopy, stimulated emission depletion (STED) microscopy, single-molecule tracking (SMT) techniques, two-photon excitation-stimulated emission depletion microscopy (TPE-STED) and fluorescence correlation spectroscopy (FCS) is discussed. These studies demonstrate that ATTO 565 plays a crucial role in areas such as biological imaging and single-molecule localization, thus warranting further in-depth investigations. Finally, we present some prospects and concepts for the future applications of ATTO 565 in the fields of biocompatibility and metal ion detection. This review does not include theoretical calculations for the ATTO 565 molecule.

In this study, multifunctional Fresnel lenses were explored as a potential solution for correcting vision in patients with color vision deficiency (CVD) and high myopia. Current studies have primarily focused on color vision correction through the 3D printing of glasses and contact lenses. However, the potential of 3D-printed multifunctional devices, such as Fresnel lenses, goes beyond addressing a single vision correction issue.

The long-lived green luminescence of human bone (that has been heated to 600 °C for a short duration) is attributed to a carbon quantum dot material (derived from collagen) encapsulated and protected by an inorganic matrix (derived from bone apatite) and is more intense in dense rigid and crystalline parts of (healthy) human bones. The strong collagen-apatite interaction results (upon decomposition) in a protective inorganic environment of the luminescent centers allowing long-lived triplet-based emission of a carbon (quantum) dot-like material at room temperature, as well as resilience against oxidation between 550 and 650 °C. The graphitic black phase (obtained upon heating around 400 °C) is a precursor to the luminescent carbon-based material, that is strongly interacting with the crystalline inorganic matrix.

Chemical conjugation of purified proteins of interest (POIs) in Escherichia coli cells is effective for high expression but has limitations for highly chromogenic dual labeling of intrinsically disordered native proteins (IDNPs). Our probes can tag IDNPs using chemical conjugation during protein synthesis and folding while preserving biologically active structures in mammalian cells. We fluorescently labeled IDNPs in mammalian cells using pure fluorescent methionine and ATTO 565-biotin at the N-or C-terminus, respectively.

Article Synopsis
- Mitochondria are essential organelles in eukaryotic cells that produce ATP and are involved in apoptosis, featuring both outer and inner membranes with a positive charge in the intermembrane space.
- Traditional fluorescent dyes for imaging mitochondria in living cells, like MitoTracker® and rhodamine 123, are unstable and can interfere with double staining due to their varied emission spectra.
- New imaging technologies, including the MitoMM1/2 dyes that are derivatives of ATTO565, have been developed to improve mitochondrial imaging, as they are sensitive to membrane potential, resistant to detergents, and do not overlap with green fluorescence, enabling better multi-color labeling.
