Self-assembly of nanostructured materials has been proven a powerful technique in material design and synthesis. By phage display screening, M13 phage was found to strongly bind sulfur particles. Fourier transform infrared and X-ray photoelectron spectroscopy measurements indicated that the strong sulfur-binding ability of M13 phage derives from newly generated S-O and C-S bonds. Using this phage assembled sulfur composite in a lithium battery, the first discharge capacity reached 1117 mAh g(-1), which is more than twice that of the sulfur only cathode. Besides, the negative polysulfide shuttle effect in a lithium-sulfur battery was significantly suppressed.

Background: Ecotoxicology is essential for the evaluation and comprehension of the effects of emergency pollutants (EP) such as heavy metal ions on the natural environment. EPs pose a substantial threat to the health of humans and the proper functioning of the global ecosystem. The primary concern is the exposure of humans and animals to heavy metal ions through contaminated water.

Food allergy is increasingly prevalent and poses notable health risks, which underscores the urgent need to develop reliable and sensitive detection methods for effective identification of food allergens. This study aims to address the limitations of existing methods by developing an immunoassay utilizing bacteriophage/carbon dots (CDs)@silica core-shell nanospheres. Two CDs with different emission wavelengths (513 nm for Green CDs, 645 nm for Red CDs) were synthesized for signal development and amplification.

Phages, as antagonists of bacteria, hold significant promise for combating drug-resistant bacterial infections. Their host specificity allows phages to target pathogenic bacteria without disrupting the gut microbiota, offering distinct advantages in the prevention and control of intestinal pathogens. The interaction between the phage and the gut plays a crucial role in the efficacy of phage-mediated bacterial killing.

Realizing plasmonic nanogaps with a refractive index ( = 1) environment in metallic nanoparticle (NP) structures is highly attractive for a wide range of applications. So far in self-assembly-based approaches, without surface functionalization of metallic NPs, achieving such extremely small nanogaps is challenging. Surface functionalization introduces changes in the refractive index at nanogaps, which in turn deteriorates the desired plasmonic properties.
