However, conventional techniques such as ICP–MS or ETAAS are accurate but unsuitable for real-time cellular imaging, and many existing fluorescent probes still face hurdles such as poor aqueous solubility and slow response kinetics. In this study, we strategically developed <strong>PPND</strong>, a naphthalimide-based fluorescent probe functionalized with pyridylpiperazine and dipicolylamine moieties.

During inkjet printing, PEI could control the migration and fixation of dye molecules on fibers through spatial effect and electrostatic interaction, achieving excellent coloring and imaging effects on untreated fabrics. The dye fixation rate exceeded 98.7 % through the synergistic effects of electrostatic attraction, covalent bonds, and hydrogen bonds. Due to pretreatment-free process and ultra-high dye fixation rate, there are low excess chemical residue on the printed fabrics, avoiding subsequent washing processes. Compared with the traditional ink, the most prominent advantage of the new ink is the excellent imaging and coloring performance, which shortens the process of inkjet printing and reduces the consumption of chemicals, water, and energy.
