Toluidine blue: A review of its chemistry and clinical utility

Flow Injection Spectrophotometric Determination of Sulphide by Catalytic Reduction of Toluidine Blue

Sulphide was determined spectrophotometrically at 628 nm and pH 6.7 based on its catalytic reduction of toluidine blue in the presence of Se(IV) using a flow injection system. After optimization of the measuring conditions the calibration curve was found linear up to 25 mg/mL and the detection limit was 0.3 mg/mL (30 mL injections). The ...

Photodynamic inactivation effect of methylene blue and toluidine blue O on ATCC Escherichia coli and clinical isolate of multidrug-resistant Escherichia coli

Magnetic Multi-Walled Carbon Nanotube as an Adsorbent for Toluidine Blue O Removal from Aqueous Solution

Toluidine Blue O (TBO) is a cationic dye which is extensively used in the industries. In the present paper a simple and efficient wet chemical method was introduced for removal of TBO from waste aqueous solution. Magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...

Catalytic Spectrophotometric Determination of Traces of Tellurium (IV)

A Simple, rapid and sensitive method has been developed for determination of trances of tellurium (VI) (0.096-1.250 mg/mL) based on its catalytic effect on the reduction reaction of toluidine blue by sulfide ion at pH 4. The reaction is monitored spectrophotometrically by measuring the decrease in absorbance of the dyestuff at 628 nm by the fixed time method. The detection...

Histo-cytological Correlation of Oral Premalignant and Malignant Lesion in Specimens from Toluidine Blue Stained Buccal Mucosa

Objective behind the study was to assess the efficacy of Toluidine Blue (TB) mouth rinse in the detection of neoplasia in oral cavity and to evaluate its usefulness in high risk groups. Correlation of the results of scrape cytology smear and histopathology of biopsy taken from the TB stained area was also done. This prospective study was carried out on 85 cases of suspected oral lesions. Comple...
