active substrate การใช้

• Indole is a particularly active substrate; the reaction provides gramine derivatives.
• For CE-SERS, capillary electrophoresis eluants can be deposited onto a SERS-active substrate.
• SERS-active substrates can be chosen that do not interfere with the spectrum of the analytes.
• Analyte retention times can be translated into spatial distance by moving the SERS-active substrate at a constant rate during capillary electrophoresis.
• A perfect overlay of multiple experiments with the same-excess but different initial substrate loadings suggests that no changes in the active substrate / catalyst concentration occur over the course of the reaction.
• The most active substrate at pH 5.0 is aminoethylcysteine ketimine ( AECK ), however at neutral pH ( pH 7.2 ) the most active substrate is 1-piperideine-2-carboxylate which is an important part of the pipecolic acid pathway.
