Stabilizing DNA G-quadruplexes by thallium(I) and its

This sensor was sensitive enough to detect Tl+ in spiked Lake Ontario water samples. The FRET based sensors demonstrated the feasibility of using PS2.M for thallium detection. A drawback to this method is the expense involved in labelling the DNA probe, and the need for a fluorometer for detection. For these reasons a colorimetric sensor was

What is the pH of water and how is pH measured? What does

Formation of the Hydrogen Ion. pH describes how acidic or basic a solution is. Whether an aqueous solution reacts as an acid or a base depends on its hydrogen ion (H +) content.In fact, the term "pH" originates from Latin and is an acronym for "potentia hydrogenii" the power of hydrogen.
