“…Um sistema de análise por injeção em fluxo para determinação de uréia empregando um reator enzimático contendo tecido de soja e quimioluminescência foi descrito por Qin et al 163 . Uma faixa linear de concentração de uréia entre 4-400x10 -6 mol L -1 com limite de detecção de 2x10 -6 mol L -1 foram obtidos e o emprego de uma resina de troca aniônica separou algumas substâncias interferentes da urina.…”

Chemiluminescence microflow-injection analysis (microFIA) systems on a chip have been developed. The technology of laser ablation was used to fabricate the microchannels on the polymethyl methacrylate (PMMA) chip. The three sampling structure, including double-tee sampling structure, microvalve sampling structure and injection pump with accurate time control, were used. The microcolumn for specific molecular recognition, including molecularly imprinted polymer, enzyme and bacteria, were used to enhance selectivity. These microFIA systems have been applied to clinical analysis, assessment of food safety, in vivo and real-time determination of drugs, and pharmacokinetics studies.

“…[14][15][16][17][18][19] Recently, a new type of sensor based on nanosized SrCO3 material was proposed by Zhang's group for the detection of ethanol. 20 A literature survey found that plant tissue-based CL sensors were reported for the analysis of glycolic acid, 21 dopamine, 22 and urea; 23 however, to the best of our knowledge, there is no report on ethanol assay by a CL sensor that is based on plant tissue as a recognition unit.…”

A plant tissue-based chemiluminescence biosensor for ethanol based on using mushroom (Agaricus bisporus) tissue as the recognition element is proposed in this paper. The principle for ethanol sensing relies on the luminol-potassium hexacyanoferrate(III)-hydrogen peroxide transducer reaction, in which hydrogen peroxide is produced from the ethanol enzymatic catalytic oxidation by oxygen under the catalysis of alcohol oxidase in the tissue column. Under optimum conditions, the method allowed the measurement of ethanol in the range of 0.001 -2 mmol/l with a detection limit (3σ) of 0.2 μmol/l. The relative standard deviation (RSD) was 4.14% (n = 11) for 0.05 mmol/l ethanol. The proposed method has been applied to the determination of ethanol in biological fluids and beverages with satisfactory results.
