Upconversion nanoparticles as intracellular pH messengers
Abstract: Upconversion nanoparticles (UCNPs) should be particularly well suited for measurement inside cells because they can be imaged down to submicrometer dimensions in near real time using fluorescence microscopy, and they...

An active DNA-based nanoprobe for photoacoustic pH imaging.
We report an active DNA construct capable of probing pH through a photoacoustic (PA) ratiometric analysis approach. Our nanoprobe enables different PA readout in tissue mimicking phantoms in the range between pH 6.8 to 7.8 at...

Sonoluminescence quenching by organic acids in aqueous solution
The quenching of sonoluminescence from aqueous solutions by acrylic and methacrylic acids is dependent on whether the acid is ionised in solution, as controlled by the pH, but also by the frequency of ultrasound used.

Effects of Copper and pH on the Growth and Physiology of Desmodesmus sp. AARLG074.
Copper (Cu) is a heavy metal that is widely used in industry and as such wastewater from mining or industrial operations can contain high levels of Cu. Some aquatic algal species can tolerate and bioaccumulate Cu and so could...

High-resolution label-free 3D mapping of extracellular pH of single living cells.
Dynamic mapping of extracellular pH (pHe) at the single-cell level is critical for understanding the role of H+ in cellular and subcellular processes, with particular importance in cancer. While several pHe sensing techniques...

pH-sensitivity of YFP provides an intracellular indicator of programmed cell death.
BACKGROUND: Programmed cell death (PCD) is an essential process for the life cycle of all multicellular organisms. In higher plants however, relatively little is known about the cascade of genes and signalling molecules...
