Metal-enhanced fluorescence through conventional Ag-polyethylene glycol nanoparticles for cellular imaging

RSC Advances (2023)

Chih‐Jung Chen Chun-Yen Wu Chi‐Wei Wu Ching‐Wen Chang Tsung‐Tao Huang

A novel application of conventional Ag nanoparticles (NPs) for metal-enhanced fluorescence (MEF) in cellular imaging is proposed. Different molecular weights of polyethylene glycol (PEG) were tested to determine a suitable spacer on Ag NPs for MEF, and NPs comprising Ag with PEG with a molecular weight of 6000 g (Ag-PEG6k), when present in fluorescein solution, were discovered to cause a 2-fold quantum yield enhancement. For fluorescence imaging of mesenchymal stem cells stained by Alexa Fluor 488, the enhancement factor increased with the Ag-PEG6k NP concentration but decreased with the Alexa Fluor 488 concentration. At 243 parts per billion Ag-PEG6k NPs and 625 parts per million Alexa Fluor 488, the enhancement factor reached its greatest value of over 4.

Poly(methacrylate)‐derived diblock dispersant for TiO₂ in aqueous suspensions

Journal of the American Ceramic Society (2017)

Chia‐Chen Li Shinn‐Jen Chang Chi‐Wei Wu Cha‐Wen Chang

Abstract In this paper, we propose a newly designed dispersant, ammonium poly(methacrylate)‐ block ‐poly(2‐phenoxyethyl acrylate) ( PMA ‐ b ‐ PBEA ), and our rheological and zeta potential test results verify its superior dispersion efficiency for aqueous suspensions in comparison to the commercial dispersant ammonium polyacrylate ( PAA ‐ NH 4 ). The extremely high dispersion efficiency of PMA ‐ b ‐ PBEA correlates closely to its diblock structure, which simultaneously exhibits a less polar anchoring head group and a water‐dissociable stabilizing moiety. The unique structure of PMA ‐ b ‐ PBEA accounts for its high powder adsorption effectiveness, which is demonstrated in its adsorption capability being double that of PAA ‐ NH 4 .
