Published: October 2017

The use of strong magnetic field gradients and high magnetic fields generated by permanent magnets or superconducting coils has found applications in many fields such as mining, solid state chemistry, biochemistry and medical research. Lab scale or industrial implementations involve separation of macro- and nanoparticles, cells, proteins, and macromolecules down to small molecules and ions. Most promising are those attempts where the object to be separated is attached to a strong magnetic nanoparticle. Here, all kinds of specific affinity interactions are used to attach magnetic carrier particles to mainly objects of biological interest. Other attempts use a strong paramagnetic suspension for the separation of purely diamagnetic objects, such as bio-macromolecules or heavy metals. The application of magnetic separation to superconducting inorganic phases is of particular interest in combination with ceramic combinatorial chemistry to generate a library of e.g. cuprate superconductors.

Flap endonuclease 1 (FEN1) plays a vital role in cancer by modulating DNA repair mechanisms, inducing genomic instability, and serving as a promising biomarker for cancer diagnosis and prognosis. In this work, we present the development of a novel DNAzyme signal amplification-directed point-of-care sensing system (Dz-PGM) for the sensitive and specific detection of FEN1. The Dz-PGM system utilizes DNAzyme signal amplification in conjunction with a personal glucose meter (PGM) for reporting, capitalizing on a biochemical cascade initiated by FEN1 recognition.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes joint damage and progressive destruction of adjacent cartilage and bones. Quick and accurate detection of rheumatoid factors (RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP) in serum is effective in diagnosing RA and preventing its progression. However, current methods for detecting these two biomarkers are costly, time-consuming, labor-intensive, and require specialized equipment.

Background: Many of the ligand affinity analyses are presented in water environment, and the hydrophilic solution such as methanol is used for dissociating the bound compounds. The obtained dissociation solution needs to be concentrated for improving the sensitivity of the assay. However, it is not good for the analysis of hydrophobic and volatile compounds such as coumarins.

Background: Polycyclic aromatic hydrocarbons (PAHs) are one of the most dangerous persistent organic pollutants in the environment. Due to the discharge of chemical plants and domestic water, the existence of PAHs in sea water and lake water is harmful to human health. A method for rapid detection and removal of PAHs in water needs to be developed.
