Degradation of olive oil under light and heat are analysed using an optical fibre based low-cost portable smartphone spectrofluorimeter. Visible fluorescence bands associated with phenolic acids, vitamins and chlorophyll centred at λ ∼ 452, 525 and 670 nm respectively are generated using near-UV excitation (LED λex ∼ 370 nm), of extra virgin olive oil are degraded more likely than refined olive oil...
A novel portable fluorometer combining the attributes of a smartphone with an easy-fit, simple and compact sample chamber fabricated using 3-D printing has been developed for pH measurements of environmental water in the field. A color filter attached over the camera white light light-emitting diode selects an excitation band centered around $\lambda \sim 450$ nm with a 3-dB bandwidth, $\Delta \lambda \sim 21$ ...
Early detection of environmental disruption, unintentional or otherwise, is increasingly desired to ensure hazard minimization in many settings. Here, using a field-portable, smartphone fluorimeter 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 custom designed Android application digitally processed and mapped the results...
Using a field portable, smartphone fluorometer for assessing water quality, a pH map of drinking water around Sydney is obtained. The work demonstrates a new security concept — network forensics — based on a novel smartgrid approach for the potential detection of water quality disruption.
