Development of highly sensitive and selective molecules for detection of spermidine and spermine.

To establish an effective and concise procedure for determining the concentrations of spermidine and spermine, several functional molecules based on phenolphthalein and two crown loops were constructed. Host 5 with a dimethylamino group showed excellent selectivity for spermidine and spermine among other biogenic amines and high sensitivity compared with basic host 1.

A new selective fluorogenic probe for trivalent cations.

A new selective chromo-fluorogenic probe for Fe(3+), Cr(3+) and Al(3+) is reported. Detection limits are in the μM range and the fluorogenic sensing ability could be observed by the naked eye when illuminated with UV-light. No response is observed with divalent cations.

Biogenic amines in sea products

Sea food products are being processed through various techniques, i.e. chilling and freezing, heating, irradiating, and curing; regard to the condition of processing, formation of biogenic amines are probable, as raw materials are usually rich in respective precursors. Fermented fish products are among the most vulnerable items to this challenge, these products due to their nutritious value are...
