“…The result showed the composite had significant antibacterial activity against both S. aureus and E. coli. Moreover, Gram-positive S. aureus seemed more sensitive than Gram-negative E. coli to the composite (Li et al 2013;Cai et al 2014). The HKUST-1/CF composite against S. aureus had (2) the preparation procedure of the HKUST-1 was the same as that of the HKUST-1/CF composite except without adding CFs (2) the preparation procedure of the CFs adsorbed Cu 2?…”

A copper-based metal-organic frameworks/cellulose fibers (HKUST-1/CF) composite was prepared by in situ and green method. Scanning electron microscopy with energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction analyses revealed the functionalization of cellulose fibers (CFs) was successfully achieved by in situ deposition of HKUST-1 via a DMF-free green process. The synthetized HKUST-1/ CF composite exhibited excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. The composite was more effective against Gram-positive S. aureus than Gram-negative E. coli. The optimization of process variables indicated that the novel composite could be prepared at room temperature for a short time.

“…Escherichia coli ( E. coli , CICC 10354) and Staphylococcus aureus ( S. aureus , CICC 10306) were selected as model gram‐negative and gram‐positive bacteria, respectively. Bacterial growth curves were investigated following the method preciously described by our group [10]. Disc diffusion method was carried out as follows: ∼10 7 –10 8 colony‐forming units of each bacterial were inoculated on LB medium solid agar Petri dish.…”

Polydopamine-functionalised graphene-Fe 3 O 4-Ag composites (PGFA) were fabricated using a facile method. The morphology, structure, and chemical components of PGFA are investigated using various techniques, including X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy. PGFA exhibits high catalytic activity for the degradation of p-nitrophenol. Furthermore, PGFA presents excellent catalytic stability and can be reused successfully for 14 cycles, maintaining high degradation efficiency (>98%). Antibacterial tests show that PGFA offers significant antibacterial potential against E. coli and S. aureus.

“…Compared with engineered templates, natural biological materials are abundant, renewable, hierarchical, and environmentally benign [ 13 , 14 , 15 , 16 ]. With respect to this, numerous studies conducted by us led to the development of a series of bio-templating methods to prepare N-I doped ZnO [ 17 ], Cu hollow spheres [ 18 ], and ZnO/graphene quantum dots (GQDs) composites [ 19 ], among others.…”

TiO2 nanoparticles are immobilized on chlorella cells using the hydrothermal method. The morphology, structure, and the visible-light-driven photocatalytic activity of the prepared chlorella/TiO2 composite are investigated by various methods. The chlorella/TiO2 composite is found to exhibit larger average sizes and higher visible-light intensities. The sensitization of the photosynthesis pigment originating from chlorella cells provides the anatase TiO2 with higher photocatalytic activities under the visible-light irradiation. The latter is linked to the highly efficient charge separation of the electron/hole pairs. The results also suggest that the photocatalytic activity of the composite remains substantial after four cycles, suggesting a good stability.
