Alpha-1-acid glycoprotein (AGP) or Orosomucoid is a serum glycoprotein which belongs to the group of acute phase proteins. It is a potential biomarker for inflammatory bowel diseases. In this sense, there is a need for developing fast and cheap analytical methods for diagnosis, prognosis and follow-up of these diseases.In this work, we propose a simple and cheap electrochemical method for total AGP...
This review covers the state of the art of the analysis of real (or non-ideal) samples on microfluidic devices. A real sample analysis performed on microfluidics conceptually involves the complete integration of sample preparation, analyte separation, and detection on these platforms. Different “lab-on-a-chip” approaches have emerged in relevant application areas such as clinical, environmental, and...
An on-line supported liquid membrane-piezoelectric detection system, based on a molecularly imprinted polymer (SLM-QCM-MIP) manifold, has been developed and applied to the quantitative determination of vanillin in food samples. The analyte is extracted from a donor phase into the hydrophobic membrane, and then back extracted into a second aqueous phase used as the acceptor solution. The quantification...
