The phenylboronic acid azoprobe (BA-Azo)/gamma-cyclodextrin (gamma-CD) complex exhibits a selective response for D-glucose by forming supramolecular 2:1 inclusion of the azoprobes with inside gamma-CD cavity.
The complete complementary code (CCC) that was proposed by Suehiro and Hatori is a sequence family, set of sets, with ideal correlation sums. Numerous studies in the literature show its applications to direct-spread code-division multiple access (DS-CDMA) systems for interchannel interference (ICI)-free communication improved spectral efficiency. In this paper, we propose systematic framework construction CCCs based on <i xmlns:mml="http://www.w3.org/1998/Math/MathML"...
There is an urgent need to develop a rapid and selective method for the detection of bacteria because delayed diagnosis overuse antibiotics have triggered drug resistance in bacteria. To this end, we prepared boronic acid-modified poly(amidoamine) generation 4 (B-PAMAM(G4)) dendrimer as cross-linking molecules that form aggregates with Within 5 min adding B-PAMAM(G4) solution bacterial suspension, large were observed. Interestingly, aggregate formation various was pH-dependent. In basic pH,...
Stable water-in-oil emulsion membranes can be prepared using [dilauryl(dimethyl)ammonium] bromide (DDAB), a cationic surfactant. We ultrasmall cyclodextrin (γ-CyD) nanogels (γ-CyDngs) by forming ionic pairs between the secondary hydroxyl groups of γ-CyDs and DDAB. Fluorescence NMR characterisation obtained γ-CyDngs revealed superior inclusion affinities compared with native γ-CyDs, beneficial for solubilisation hydrophobic compounds in water.
Abstract Background Self‐help programs without therapist involvement for obsessive–compulsive disorder (OCD) are promising, but the high dropout rate is a significant issue. Our software, which incorporates entertainment elements, showed completion of over 80% in pre–post comparison study, with superior effectiveness. This protocol study that aims to evaluate efficacy and tolerability video‐based mobile application OCD treatment through randomized controlled trial. Methods designed as trial...
Binuclear β-diketonatoruthenium(III) complexes [{Ru(acac)2}2(tae)], [{Ru(phpa)2}2(tae)], and [(acac)2Ru(tae)Ru(phpa)2] binuclear mononuclear bipyridine [{Ru(bpy)2}2(tae)](PF6)2 [Ru(bpy)2(Htae)]PF6 (acac = 2,4-pentanedionate ion, phpa 2,2,6,6-tetramethyl-3,5-heptanedionate tae 1,1,2,2-tetraacetylethanate dianion, bpy 2,2'-bipyridine) were synthesized. The new have been characterized by 1H NMR, MS, electronic spectral data. Crystal molecular structures of [{Ru(acac)2}2(tae)] solved...
In this study, we have developed a rational design strategy to obtain highly selective supramolecular recognition systems of cyclodextrins (CyDs) on the basis lock and key principle. We designed synthesized dipicolylamine (dpa)-modified γ-CyD-Cu2+ complexes possessing an azobenzene unit (Cu·1-γ-CyD) examined how they recognized phosphoric acid derivatives in water. The results revealed that Cu·1-γ-CyD ATP with high selectivity over other derivatives. significant blue shift UV-vis spectra 1H...
Fluorescence recognition of d-glucose in water with excellent sensitivity, selectivity, and chiral selectivity is desired because an essential component biological pathological processes. We report innovative approach that exploits the 1:2 stoichiometric inclusion complexes γ-cyclodextrin (γ-CyD) two molecules fluorescent monoboronic acid-based receptors, which form a pseudo-diboronic acid moiety as site for water. Two acids (1F 2N) were easily synthesized without heating or column...
Nanomaterial-based photothermal therapy is a noninvasive treatment approach that selectively destroys cancer cells by utilizing the ability of nanomaterials to convert photon energy into heat. Although plasmonic gold nanoparticles are promising, this study focuses on developing cost-effective alternatives. We developed aluminum open-shell nanostructures (AlOSNs) as symmetry-breaking structures nanoshells for purpose. The intrinsic low chemical stability AlOSNs in aqueous media (water and...
Abstract A solid‐phase extraction (SPE)‐gas chromatography (GC)‐mass spectrometry (MS) analytical method was developed for the simultaneous analysis of natural free estrogens and their conjugates in wastewater samples. Natural were successfully separated by oasis hydrophilic‐lipophilic balance solid phase (Oasis HLB SPE) method, initially enzyme hydrolyzed β‐glucuronidase or arylsulfatase from Helix pomatia prior to derivatization. N ‐methyl‐ ‐(tert‐butyldimethylsilyl)trifluoroacetamide...
ATP recognition has been achieved by exploiting the self-assembly of boronic acid-appended cyclodextrin, a fluorescent probe, and through multiple interactions.
Lipopolysaccharide (LPS) is a bacterial toxin that causes fever in humans. Our small-molecule chemosensor named Zn-dpa-C2OPy shows rapid ratiometric fluorescence response to LPS water with detection limit of 11 pM, which lower than our previously reported sensor. Spectroscopic measurements (fluorescence, absorbance, 1H NMR, and lifetime), dynamic light scattering measurements, transmission electron microscopy observations revealed the was induced by changes aggregation state via multi-point...
Various diboronic acid-based chemosensors for d-glucose have been developed use in diabetes diagnostic systems. However, most of these limitations, such as poor water solubility, difficulties synthesis, and inability to selectively detect from among other saccharides. We report a simple chemosensor based on supramolecular complex fluorophenylboronic acid-appended β-cyclodextrin (FPB-βCyD) an anthracene-based probe having boronic acid moiety (1). Hydrophobic 1 is encapsulated the cyclodextrin...
