Abstract
Biomacromolecules are viewed as promising drugs due to their specific functions in biological processes, biocompatibility, and pharmacological efficacy. Injective administration, chosen to avoid intestinal barriers, may in turn lead to immediate decay in the circulation system, unreliable targeting performance, or the induction of immune responses. For some biomacromolecules, chemically modified proteins have been developed for practical use. Various cargo or carrier systems are under development but have been delayed by technical difficulties. We present self-assembled nanocapsules with diameters ranging from 100 to 500 nm that can be deployed in physiological buffers to enclose various substances present in the buffers at the same time. Our amphiphilic nanocapsule, consisting of silole-core dendrimer products as the hydrophobic part and green fluorescent protein (GFP) derivatives as the hydrophilic part, connects and assembles spontaneously when mixed in solutions while engulfing dissolved or dispersed compounds together in a dose-dependent manner and shows unique optical characteristics because the dendrimer products exhibit aggregation-induced emission. Furthermore, the emission of the dendrimer causes considerable fluorescence resonance energy transfer (FRET) to GFP derivatives upon association. We could easily monitor assemblies by FRET states and particle sizes and have confirmed a stable presence in the buffer for at least a month. Further tracking of nanocapsules by fluorescence confirmed efficient uptake into some cancer cells. Nanocapsules based on GFP variants with or without a cell-surface-specific tag demonstrated that the tag improved the potential for specific targeted delivery. There were also indications that the nanocapsules became unstable after cellular uptake in the intracellular environment. We report here the simple preparation of traceable, stable, and biocompatible self-assembled nanocapsules as the basis for a versatile drug delivery system.

Abstract
Here, we report the simple construction of a supramolecular glycomaterial for the targeted delivery of antibiotics to P. aeruginosa in a photothermally-controlled manner. A galactose-pyrene conjugate (Gal-pyr) was developed to self-assemble with graphene nanoribbon-based nanowires via π-π stacking to produce a supramolecular glycomaterial, which exhibits a 1250-fold enhanced binding avidity toward a galactose-selective lectin when compared to Gal-pyr. The as-prepared glycomaterial when loaded with an antibiotic that acts as an inhibitor of the bacterial folic acid biosynthetic pathway eradicated P. aeruginosa-derived biofilms under near-infrared light irradiation due to the strong photothermal effect of the nanowires accelerating antibiotic release.

Abstract
The detection of Ag+ in the environment is very important to determine the level of pollution from silver complexes, which have caused various human health problems. Herein, an aggregation-induced emission (AIE) chromophore (tetraphenylethane, TPE) attached to a benzimidazole group (tetra-benzimidazole, TBI–TPE) is synthesized and utilized to detect Ag+ in the environment. The strong chelating effect between the benzimidazole group and Ag+ leads to the formation of aggregates, and strong yellow fluorescence signals were observed after adding Ag+ into a TBI–TPE solution. The stoichiometry of the complex of TBI–TPE and Ag+ was established to be 1 : 2 using photochemical and mass spectra measurements. The detection limit of the Ag+ assay is 90 nM with a linear range from 100 nM to 6 μM. This study provides a facile method to determine Ag+ in real environmental samples with satisfactory results. We develop a highly selective TPE-based AIE fluorescent probe containing a benzimidazole group for the detection of Ag+.![]()

Abstract
Nanomaterials constitute a class of structures that have unique physiochemical properties and are excellent scaffolds for presenting carbohydrates, important biomolecules that mediate a wide variety of important biological events. The fabrication of carbohydrate-presenting nanomaterials, glyconanomaterials, is of high interest and utility, combining the features of nanoscale objects with biomolecular recognition. The structures can also produce strong multivalent effects, where the nanomaterial scaffold greatly enhances the relatively weak affinities of single carbohydrate ligands to the corresponding receptors, and effectively amplifies the carbohydrate-mediated interactions. Glyconanomaterials are thus an appealing platform for biosensing applications. In this review, we discuss the chemistry for conjugation of carbohydrates to nanomaterials, summarize strategies, and tabulate examples of applying glyconanomaterials in in vitro and in vivo sensing applications of proteins, microbes, and cells. The limitations and future perspectives of these emerging glyconanomaterials sensing systems are furthermore discussed.

Abstract
Two new strongly AEE active (I/I0 ≈ 94) tetraphenylsilole-containing cyclosiloxanes with cyan emissions (λem = 500 nm) and ∼100% solid state fluorescence quantum yields are reported. The intra- and intermolecular C-Hπ interactions in the crystal play a major role in the observed high solid state fluorescence quantum yields.

Abstract
Specific bioprobes with fluorescence turn-on response are highly desirable for high contrast biosensing and imaging. In this work, we developed a new generation bioprobe by integrating tetraphenylsilole, a fluorogenic unit with aggregation-induced emission (AIE) characteristic, with cyclic arginine-glycine-aspartic acid tripeptide (cRGD), a targeting ligand to integrin α(v)β(3) receptor. Emission of the AIE probe is switched on upon its specific binding to integrin α(v)β(3), which allows quantitative detection of integrin α(v)β(3) in solution and real-time imaging of the binding process between cRGD and integrin α(v)β(3) on cell membrane. The probe can be used for tracking integrin α(v)β(3) and for identifying integrin α(v)β(3)-positive cancer cells.
