CY5-Dextran (MW60-80k) is a fluorescent probe formed by covalent conjugation of the cyanine dye Cy5 to dextran. It is a pH-insensitive fluid-phase endocytosis tracer (the pH of endosomal lumen is precisely quantified by the fluorescence ratio of FITC/Cy5). CY5-Dextran (MW60-80k) is internalized by cells via a clathrin-independent fluid-phase pinocytosis pathway, and is sequentially evidenced by early endosomes, late endosomes are transported to lysosomes. CY5-D I cannot pass through the limited pore size formed by uncoating of human rhinovirus type 2 (HRV2), but can be released into the neutral cytoplasm upon adenovirus-mediated endosomal rupture, thus distinguishing between the two viral modes of "pore-forming escape" and "lysis escape". CY5-Dextran (MW60) -80k) has an excitation wavelength of 635 nm, and it can also be used for time-lapse imaging of endocytosis dynamics of stromal cells in tissues such as rat salivary glands under in vivo two-photon microscopy .

DXB-NIR is a push-pull dioxaboron fluorescent probe with solvatochromic properties, featuring high fluorescence brightness, photostability, and a large two-photon absorption cross-section. DXB-NIR exhibits Ex/Em of 550/620–780 nm (with two-photon excitation at 930 nm). DXB-NIR quantifies local polarity via the intensity ratio I (>640)/I (<640) between the far-red channel (<640 nm) and the near-infrared channel (>640 nm), and it can simultaneously label the plasma membrane, endoplasmic reticulum, and lipid droplets in live cells. DXB-NIR monitors the increase in local polarity of various cell compartments under conditions of cholesterol depletion, starvation, and oxidative stress. DXB-NIR can be used for polarity imaging of biological membranes and lipid droplets, as well as studies related to cellular stress .

CQPP is a Fluorescent probe designed for monitoring polarity changes in the cellular microenvironment, including polarity tracking of lipid droplets/nuclei during ferroptosis. CQPP exhibits ratiometric fluorescence emission and fluorescence lifetime variations in response to polarity changes; a nonpolar environment stimulates fluorescence from the locally excited (LE) state, while a polar environment drives solvation relaxation to the intramolecular charge transfer (ICT) state, which attenuates the LE emission at ~470 nm and simultaneously enhances the ICT emission at ~670 nm. CQPP binds to intranuclear DNA through electrostatic interactions and hydrogen bonds in the DNA minor groove, which enhances its emission at ~670 nm and prolongs its fluorescence lifetime. CQPP can simultaneously target lipid droplets (green LE fluorescence) and the nucleus (red ICT fluorescence). The detection wavelengths of CQPP are Ex/Em = 405/470 nm and Ex/Em = 405/670 nm, and it also supports fluorescence lifetime imaging via 810 nm two-photon excitation .
