From flow injection to bead injection.
In this Report, we introduce a new methodology applicable to the entire range of traditional reagent and solid-phase assays. Known as bead injection (BI), this technique influences diverse fields of research, including chemical sensors, microfabrication, bioassays, affinity chromatography, spectrophotometry, and electrochemistry. This is because BI combines the advantages of solid-phase chemist...
متن کاملBead-injection determination of total mercury in river water samples.
A bead-injection system is proposed for total mercury determination in river-water samples. The procedure is based on the introduction of a defined quantity of a resin suspension in the flow system. The selected beads are packed inside of a flow cell and the formed resin mini-column constitutes the optical path. The sample volume is then selected, and its passage by the mini-column allows reten...
متن کاملUltrasonic enhancement of bead-based bioaffinity assays.
Ultrasonic radiation forces can be used for non-intrusive manipulation and concentration of suspended micrometer-sized particles. For bioanalytical purposes, standing-wave ultrasound has long been used for rapid immuno-agglutination of functionalized latex beads. More recently, detection methods based on laser-scanning fluorometry and single-step homogeneous bead-based assays show promise for f...

متن کاملExploiting the bead injection LOV approach to carry out spectrophotometric assays in wine: application to the determination of iron.
A sequential injection lab-on-valve (SI-LOV) system was used to develop a new methodology for the determination of iron in wine samples exploiting the bead injection (BI) concept for solid phase extraction and spectrophotometric measurement. Nitrilotriacetic Acid (NTA) Superflow resin was used to build the bead column of the flow through sensor. The iron (III) ions were retained by the bead col...
