Protein-Encapsulated Catalysts: WO₃ Nanofiber-Based Biomarker Detectors Enabled by Protein-Encapsulated Catalyst Self-Assembled on Polystyrene Colloid Templates (Small 7/2016)

A novel catalyst functionalization method is proposed by I.-D. Kim and co-workers using the self-assembly of protein-encapsulated catalytic nanoparticles on polystyrene colloid templates. On page 911, these templates are employed in electrospinning to achieve well-dispersed catalyst functionalization as well as to form open pores on WO3 nanofibers (NFs) after subsequent heat-treatment. The improved analyte-sensing performance is investigated with catalyst-loaded porous WO3 NFs, demonstrating their potential for application in exhaled breath analysis to diagnose diseases.
