Disentangling the chemistry of Australian plant exudates from a unique historical collection

For thousands of years, the unique physicochemical properties of plant exudates have defined uses in material culture and practical applications. Native Australian plant exudates, including resins, kinos, and gums, have been used and continue to be…

X-ray irradiation effects on Egyptian blue and green pigments

Egyptian blue and green are among the oldest synthetic pigments produced by humanity. The two pigments are complex multi-phase copper-based systems synthesised with different protocols from the same raw materials. Since the 2000s, synchrotron X-ray…

Burning TADF solids reveals their excitons’ mobility

Nowadays, Thermally Activated Delayed Fluorescence (TADF) compounds have proven to be attractive for highly efficient optoelectronic devices as they can exploit both singlet and triplet excited states generated by charge recombinations that occur in…

Coating gold nanorods with silica prevents the generation of reactive oxygen species under laser light irradiation for safe biomedical applications

Gold nanoparticles can produce reactive oxygen species (ROS) under the action of ultrashort pulsed light. While beneficial for photodynamic therapy, this phenomenon is prohibitive for other biomedical applications such as imaging, photo-thermal drug…

FRET-mediated quenching of BODIPY fluorescent nanoparticles by methylene blue and its application to bacterial imaging

High resolution and good signal to noise ratio is a requirement in cell imaging. However, after labelling with fluorescent entities, and besides several washing steps, there is often an unwanted fluorescent background that reduces the images…

How to do photophysics with daily life products

Fluorescence is defined as the emission of light by a substance during its irradiation by electromagnetic radiation. For organic compounds, such phenomena is called molecular fluorescence and the light source for the irradiation is usually UV or…
