“…[28] In 2002, Weston and Wang reported the ability to target a specific oligosaccharide epitope of a cell surface glycoconjugate. [60,61] Use of a fluorescent bis-boronate to label the cancerrelated antigen sialyl Lewis X on hepatocellular carcinoma cells was an important achievement. They used a combinatorial approach to optimize a bis-boronate in targeting the sialic acid and fucose residues on the tetrasaccharide.…”

High-performance carbon nanotubes-supported Pt catalysts (Pt/CNTs) catalysts were prepared on the basis of Pt precursors reduced by hydrogen plasma (Pt/CNTs-HP) generated by microwave. The other two Pt/CNTs catalysts prepared by hydrogen (Pt/CNTs-H) and NaBH 4 (Pt/CNTs-N) reduction were also involved for comparison. The practical composition of the catalysts was characterized with energy dispersive analysis of X-ray (EDAX). It was shown from transmission electron microscopy (TEM) and X-ray di®raction (XRD) that the Pt nanoparticles in Pt/CNTs-HP were uniformly dispersed on CNTs with smaller particle size around 2 nm and narrower size distribution as compared with the other two catalysts. Additionally, X-ray photoelectron spectrum (XPS) analysis indicated higher amount of zero-valence states of Pt in Pt/CNTs-HP caused by hydrogen plasma treatment. The electrooxidation of liquid methanol on these catalysts was investigated by cyclic voltammetry (CV), linear sweep voltammetry (LSV) and chronoamperometry. The long-time durability is very comparable to all the three catalysts. Remarkably, the Pt/CNTs-HP possessed the highest electrocatalytic activity, suggesting that the hydrogen plasma reduction approach can be a promising reduction method for preparing high-performance Pt-based electrocatalysts.

“…However, they have found wider applications more recently as sensors of 'gallate-like′ compounds in the alcoholic beverage industry (Wiskur & Anslyn, 2001), in the development of saccharide sensors (in vivo at neutral pH in aqueous environment) (Baxter et al, 1990;Fedorak et al, 1989;Yamamoto et al, 1990;Yasuda et al, 1990), boronolectins (Yang et al, 2002(Yang et al, , 2004, as protease (Fevig et al, 1996;Kettner et al, 1990;Prusoff et al, 1993), glycosidase (Johnson & Houston, 2002) and proteasome inhibitors (Adams et al, 1998).…”

Key indicators: single-crystal X-ray study; T = 150 K; mean (C-C) = 0.002 Å; R factor = 0.044; wR factor = 0.114; data-to-parameter ratio = 17.3.The six-membered boronate ester ring of the title compound, C 13 H 16 BNO 6 , adopts an envelope conformation with the C atom bearing the dimethyl substituents at the flap. The O-B-C-C torsion angles between the boronate group and the benzene ring are 72.5 (2) and 81.0 (2) . The 4-nitrobenzoate unit adopts a slightly twisted conformation, with dihedral angles between the benzene ring and the nitrate and methyl ester groups of 17.5 (2) and 14.4 (3) , respectively. In the crystal, inversion-related pairs of molecules show weak -stacking interactions [centroid-centroid distance = 4.0585 (9) Å and interplanar spacing = 3.6254 (7) Å ]. Related literature
