The ideal anticancer drug would be one that is effective at killing rapidly producing cells, is targeted directly to the tumour location, and is non-toxic until it reaches the diseased area. Platinum-II (PtII) based chemotherapy drugs have been life changing for many, with the most common drug, Cisplatin, providing treatment and cures for cancerous diseases in the bladder, breast, cervix, lung, ovaries, and head and neck, to name a few.

Understanding and optimising novel materials for the next generation of fuel sources for our energy needs that are efficient, affordable, and carbon neutral is of paramount importance for generations to come. Photocatalytic materials that can harvest sunlight and generate hydrogen gas (H2) from water is highly sought after given the enormous energy released and environmentally friendly by-product of water when burning this gas for energy. Find out more.

This customer written application note describes how to measure the two-photon absorption spectra of fluorescent chromophores by using an external short-pulsed laser source in an Edinburgh Instruments FS5 Spectrofluorometer. A procedure on how to calculate the nonlinear refraction dispersion from the measured spectra is also given.

Researchers in Fujian, China, led by Rong Cao and Zu-Jin Lin, have developed a new method for sensing ClO- employing fluorescence spectroscopy and novel metal organic frameworks. The authors used an Edinburgh Instruments FS5 Spectrofluorometer to characterize and optimise the sensor’s response towards ClO- . They then employed this sensor to detect ascorbic acid, an essential nutrient for the human body.
