Intelligent smartphone-based portable network diagnostics for water security Case Study realtime pH mapping of tap water
Arafat Hossain, John Canning, Sandra Ast +2
Using a field-portable, smartphone fluorometer to assess water quality based on the pH response of a designer probe, a map of pH of public tap water sites has been obtained. A cust…
Near orthogonal launch of SPR modes in Au films
John Canning, Akib Karim, Nikki Tzoumis +3
We report the excitation of a surface plasmon resonance (SPR) close to the orthogonal axis of a gold (Au) film on borosilicate glass. Direct spectroscopic measurement of SPR shifts…
Lab-in-a-phone: Smartphone-based Portable Fluorometer for pH Field Measurements of Environmental Water
Md. Arafat Hossain, John Canning, Sandra Ast +3
A novel portable fluorometer combining the attributes of a smartphone with an easy fit, simple and compact sample chamber fabricated using 3D printing has been developed for pH mea…
Percolation diffusion into self-assembled mesoporous silica microfibres
John Canning, George Huyang, Miles Ma +7
Percolation diffusion into long (11.5 cm) self-assembled, ordered mesoporous microfibres is studied using optical transmission and laser ablation inductive coupled mass spectrometr…
