A Novel PDMS-Based Digital Magnetofluidic Platform for Lab-on-a-Chip Applications

Research highlight / By

Superhydrophobic gold film embedded PDMS was employed as a novel platform for digital magnetofluidics. The device performance for lab-on-a-chip applications was investigated by demonstrating four types of reactions: (i) acid-based titration as a simple mixing reaction, (ii) colorimetric detection of phosphate based on the molybdenum blue method as a more complicated reaction, (iii) colorimetric detection …

Synergistic Redox of Dual-Shaped Silver Nanostructures for Highly Selective Sensing of Hydrogen Peroxide

Research highlight / By

A novel growth-based plasmonic sensor for H2O2 determination was developed from dual-shaped silver nanostructures consisting of starch-stabilized yellow silver nanospheres (AgNSs) and citrate-capped red silver nanoprisms (AgNPrs). The unique ability of H2O2 to oxidize silver nanoparticles and reduce silver ion consequently was exploited to produce a highly sensitive and selective sensor (AgNSs/NPrs). AgNPrs were enlarged …

Development and Application of Novel Multiloop Splitter-based Non-cryogenic Artificial Trapping (M-SNAT) Modulation System in Comprehensive Two-Dimensional Gas Chromatography

Research highlight / By

Comprehensive two-dimensional gas chromatography (GC×GC) offers high resolution and enhanced peak capacity separating complex samples, e.g. petrochemicals, essential oils, food or biological. This technique provides enhanced peak capacity and selectivity compared with that obtained from one dimensional GC. In this research, Assist. Prof. Dr. Chadin Kulsing and Dr. Nuttanee Tungkijanansin (Postdoctoral researcher) developed splitter-based non-cryogenic …
