چکیده

A new saccharides sensor based on the TTF-anthracene dyad with two boronic acid (2) groups was designed and synthesized. This new saccharides sensor shows selectivity towards D-glucose while its analogue with one boronic acid group (1) was reported to bind D-Fructose selectively. Moreover, reaction of compound 2 with uridine induced even larger fluorescence enhancement under the same condition.

A new chemiluminescence probe for singlet oxygen based on tetrathiafulvalene-anthracene dyad capable of performing detection in water/alcohol solution.

A new tetrathiafulvalene-anthracene dyad 1 with two "tetraethylene glycol" units was synthesized and characterized. Strong chemiluminescence was observed upon reaction of dyad 1 with singlet oxygen (1O2), and this reaction shows fairly good selectivity toward 1O2 over other reactive oxygen species. Due to the introduction of two hydrophilic "tetraethylene glycol" units, the detection of 1O2 wit...

Glucose selective surface plasmon resonance-based bis-boronic acid sensor.

Saccharides - a versatile class of biologically important molecules - are involved in a variety of physiological and pathological processes, but their detection and quantification is challenging. Herein, surface plasmon resonance and self-assembled monolayers on gold generated from bis-boronic acid bearing a thioctic acid moiety, whose intramolecular distance between the boronic acid moieties i...

Exploiting the reversible covalent bonding of boronic acids: recognition, sensing, and assembly.

Boronic acids can interact with Lewis bases to generate boronate anions, and they can also bind with diol units to form cyclic boronate esters. Boronic acid based receptor designs originated when Lorand and Edwards used the pH drop observed upon the addition of saccharides to boronic acids to determine their association constants. The inherent acidity of the boronic acid is enhanced when 1,2-, ...

Screening of boronic acids for strong inhibition of the hydrolytic activity of a-chymotrypsin and for sugar sensing associated with a large fluorescence change

The inhibitory effect of arylboronic acids which act as a transition state analogue for certain peptidases is efficiently intensified by added saccharides: this finding enables us to control the enzyme activity by a combination of arylboronic acids and polyols including sugars. In particular, the combined system of 3-biphenylboronic acid and D-glucose strongly inhibited the hydrolysis reaction ...

A bis-boronic acid modified electrode for the sensitive and selective determination of glucose concentrations.

A bis-boronic acid modified electrode for the sensitive and selective determination of glucose concentrations has been developed. The electrochemical characteristics of the sensor with added saccharides were investigated using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The bis-boronic acid modified electrode was both sensitive and selective for glucose.
