Buffers

open access: yesCold Spring Harbor Protocols, 2018
Biological reactions work well only within a narrow concentration range of hydrogen ions. Paradoxically, however, many of these reactions themselves generate or consume protons. Buffers are substances that undergo reversible protonation within a particular pH range and therefore maintain the concentration of hydrogen ions within acceptable limits. This

Changing the Buffer in Buffered Lidocaine

Journal of Infusion Nursing, 2022
Hospitalized patients require venous access for procedures, treatments, or therapies. The use of lidocaine for pain relief during central vascular access device (CVAD) insertion is a standard of practice. Lidocaine buffered with sodium bicarbonate has been shown to provide significantly more pain relief in the sensation of pain upon injection ...

Kinetic Buffers

ChemPhysChem, 2014
AbstractThis paper proposes a new type of molecular device that is able to act as an inverse proton sponge to slowly decrease the pH inside a reaction vessel. This makes the automatic monitoring of the concentration of pH‐sensitive systems possible. The device is a composite formed of an alkyl chloride, which kinetically produces acidity, and a buffer ...
