“…In order to further understand the chemical composition and surface element state of E-GFs, BSA-GFs, BGGs, and BRNGs, XPS characterization was used, and the results are shown in Figure b–i. The full XPS pattern of E-GFs, BSA-GFs, and BGGs exhibits the existence of C, N, Si, and O elements, and the survey spectrum of BRNGs shows new elements such as Ni and P. In the high-resolution C 1s XPS spectra of E-GFs, characteristic peaks located at 288.3 and 284.5 eV are attributed to −CO and C–C, respectively (Figure c). , Compared with E-GFs, new peaks located at 286.2 and 285.3 eV are ascribed to C–O and C–N in the high-resolution C 1s XPS spectra of BSA-GFs, respectively (Figure d). , For narrow scans of E-GFs and BSA-GFs, the intensity of N 1s is significantly enhanced and peak of −N (399.8 eV) can be observed (Figure g,h) . The presence of C–O, C–N, and −N indicates that BSA is adhered on the surface of GFs.…”

With the rapid development of information technology, the application scenarios of electromagnetic interference (EMI) shielding materials are more diversified. It is difficult for traditional EMI shielding materials to possess low density, high EMI shielding performance, strength, and flexibility in extreme environments such as oxidation/deformation/salt/alkali/high temperature/impact energy/bacteria. Herein, reduced graphene oxide nanosheets (RGO) and Ni nanoparticles were subsequently coated on glass fabrics (GFs) modified with bovine serum albumin (BSA) by adhesion, electrostatic adsorption, and metallization. A 1D glass fiber modified with BSA was used as a flexible substrate, while 2D RGO nanosheets that adhered on the surface of the abovementioned fibers provide a large specific surface area and structural defects and further promote the anchoring of 0D Ni nanoparticles. 2D/1D/0D construction shows an excellent synergistic effect, which promotes the formation of a firm conductive network and lays the foundation for multifunction. EMI shielding efficiency (EMI SE) of the prepared BSA/RGO/Ni-GFs (BRNGs) ranges from 52 to 72 dB in the range of 2−18 GHz. 2D/1D/0D BRNGs with flexibility also show fantastic binding fastness (EMI SE maintaining 89.1 and 86.0% after repeated bending 400 cycles at 90°and ultrasonic damage for 1 h, respectively) and chemical stability (EMI SE remaining 80.2, 95.3, and 92.6% after 200 °C oxidation for 12 h and salt/alkali corrosion for 12 h). In addition, Joule heating, photothermal properties, contact angle, heat dissipation, and mechanical and antibacterial properties of BRNGs were tested. The integration of excellent energy conversion, heat dissipation, and mechanical strength further improves the practicability of the electromagnetic shielding material. Antibacterial and hydrophobic properties of BRNGs are also beneficial to prolong the service life. This study provides a new idea for the design of multifunctional electromagnetic shielding composites.

Bone tuberculosis, an extrapulmonary manifestation of tuberculosis, presents unique treatment challenges, including its insidious onset and complex pathology. While advancements in anti-tubercular therapy have been made, the efficacy is often limited by difficulties in achieving targeted drug concentrations and avoiding systemic toxicity. The intricate bone structure and presence of granulomas further impede effective drug delivery. Nano-drug delivery systems have emerged as a promising alternative, offering the enhanced targeting of anti-tubercular drugs. These systems, characterized by their minute size and adaptable surface properties, can be tailored to improve drug solubility, stability, and bioavailability, while also responding to specific stimuli within the bone TB microenvironment for controlled drug release. Nano-drug delivery systems can encapsulate drugs for precise delivery to the infection site. A significant innovation is their integration with prosthetics or biomaterials, which aids in both drug delivery and bone reconstruction, addressing the infection and its osteological consequences. This review provides a comprehensive overview of the pathophysiology of bone tuberculosis and its current treatments, emphasizing their limitations. It then delves into the advancements in nano-drug delivery systems, discussing their design, functionality, and role in bone TB therapy. The review assesses their potential in preclinical research, particularly in targeted drug delivery, treatment efficacy, and a reduction of side effects. Finally, it highlights the transformative promise of nanotechnology in bone TB treatments and suggests future research directions in this evolving field.

“…Fluorescence spectroscopy is an important method to study the interactions of biological macromolecules with small molecules and ions. 28,29 The emission characteristics, fluorescence polarization, energy transfer and fluorescence lifetime obtained in the fluorescence tests provide useful information on the structure of the fluorescent chromophore and the microenvironment in which it is located. [30][31][32] Therefore, fluorescence spectroscopy is a simple and sensitive method, which requires only a small amount of sample, to quantitatively study the interactions between BSA and small molecules, to calculate the binding constants, binding sites, and many thermodynamic and kinetic parameters.…”
