Summary: In this study, a pH-responsive gold nanoparticle assembly (RGA) assisted by i-motif DNA was developed for highly sensitive and reversible response to pH changes between 6.20 and 7.40. The acidic pH triggers disassembly of RGA, changing the color from blue-purple to red, allowing pH estimation by naked-eye determination or UVevis spectroscopy. Furthermore, the RGA can detect slight pH fluctuations in catalytic reactions, providing a new strategy for on-site and real-time pH sensing.

Summary: This study describes the reversible self-assembly of plasmonic nanoparticles capped with complementary copolymer ligands into colloidal molecules via halogen bonding interactions. The coordination number of the colloidal molecules is determined by the number ratio of complementary halogen groups on the interacting nanoparticles. The reversibility of the halogen bonds allows for controlling the formation and disassociation of the colloidal molecules and their optical properties. The engineered reversible nanostructures may have applications in sensing, catalysis, and optoelectronic devices.

Summary: The design of endogenous stimuli-responsive amino acids allows for precise modulation of proteins or peptides under a biological microenvironment, as demonstrated in the development of efficient hypoxia imaging probes using a noncanonical amino acid. The unique properties of the synthesized amino acid facilitate the creation of aromatic peptides undergoing NTR-responsive self-assembly, leading to the development of morphology-transformable supramolecular probes for imaging hypoxic tumor cells. This versatile amino acid provides a powerful toolkit for synthetic biology and the creation of novel biomaterials responsive to biological environments.

Summary: This study demonstrates local, subdiffraction limited chiral coupling of light and propagating surface plasmon polaritons in a self-assembled system. Characterization of the nanoantenna-nanowire systems is done comprehensively through various imaging techniques, supported by three-dimensional numerical simulations. The system shows promise for on-chip sensing of chiral analytes far below the diffraction limit.

Summary: A FRET-labeled microenvironment-responsive immunosensor modulated by AChE was designed to enhance sensitivity to AFB1. By reducing the microenvironment pH around UCNPs and destroying UCNP-FITC for signal amplification, this system achieved quantitative determination of AFB1 with LODs as low as 0.003 nM, demonstrating a promising approach for future research in up-conversion fluorescence sensing.

Summary: This paper presents a novel method for direct reversible self-assembly and dis-assembly of Au nanoparticles in water driven by pH stimuli. By controlling the condensation and decomposition of 3-aminopropyltriethoxysilane, plasmonic color switching among adjacent AuNPs can be achieved, offering a new avenue for regulating plasmonic properties of nanoparticles.

Summary: A universal strategy for designing pH probes using the pH-dependent reversible intramolecular reaction of spiro-oxazolidine was developed, leading to short emission in basic conditions and significantly red-shifted emission in acidic environments. The emission shift of the probes exceeded 150 nm, with one probe demonstrating a shift of up to 210 nm, outperforming commercial and reported pH probes. The chemical sensing mechanism was confirmed through H-1 NMR spectra and density functional theory calculations, and the probes were successfully used to image lysosomal pH changes in a ratiometric manner.

Summary: Due to low losses, optical fibers are excellent waveguides, but manipulating the wavefront below the diffraction limit while keeping fabrication costs down is a challenge. We present a coating method using gold nanoparticles to achieve plasmonic gratings on rough surfaces, enabling the fabrication of low-cost fiber-based sensors with low optical losses.
