By integrating experimental analyses (FTIR, XRD, rheology) with molecular dynamics (MD) simulations, we demonstrate that Gli and Glu exhibit stronger non-covalent binding to starch than Glo, driven by hydrophobic forces and hydrogen bonding. These interactions disrupt starch chain entanglement, reduce short- and long-range structural order, and inhibit α-amylase activity.

Accurate visualization of vascular structures, as well as real-time monitoring of hemodynamic parameters and molecular profiles associated with vascular function, are therefore crucial for early diagnosis and preventive interventions of vascular diseases. Fluorescence imaging technology, particularly in the second near-infrared window (NIR-II; 1000–1700 nm), offers distinct advantages for these demanding imaging requirements not only due to its high sensitivity, excellent spatial resolution, and real-time monitoring capability but also thanks to the superior signal-to-background ratio and large tissue penetration depth of NIR-II fluorescence.

The traditional clinical treatment for TB is long-term and combined usage of antibiotics but suffers from poor lesion and pathogen targeting, insufficient efficacy, high systemic toxicity, and ineffectiveness against drug-resistant <i>M. tuberculosis</i>. As a characteristic lesion of TB, granulomas have a compact construction, which greatly limits the access of small-molecule antibiotics to the necrotic area to kill <i>M. tuberculosis</i> [<span>1</span>]. Moreover, <i>M. tuberculosis</i> bacilli, which are quiescent within the granulomas, are phenotypically resistant to traditional antibiotics. These factors contribute to the poor outcomes of conventional antibiotic regimens. So far, several types of nanodrugs including PEGylated liposomes, PEGylated quantum dots, and polymer micelles have been studied with the aim of granuloma targeting [<span>2, 3</span>]. However, these nanoparticles (NPs) cannot achieve specific targeting of <i>M. tuberculosis</i>.
