“…These methods include spectroscopic technique [2][3][4], titration [5], microbiological methods [6] and HPLC [7][8][9][10][11][12]. For the analysis of complex biological samples, spectrometry and titration are not suitable, while microbiological methods are tedious and time-consuming.…”

Abstract:To obtain molecularly imprinted polymers capable of selective rebinding with nicotinamide (NAM), NAM imprinted polymers were synthesized via bulk polymerization using various functional monomers and cross-linkers. The NAM recognition properties of these polymers were investigated in organic and aqueous solvents by equilibrium rebinding experiments. The results show that the imprinted polymer prepared using 1:4:4 molar ratio of NAM/MAA/TRIM in dichloromethane exhibited the greatest NAM binding capacity and selectivity. This polymer is potentially valuable for the analysis of NAM in complex matrices where selective isolation and identification are needed.

“…Vitamin B« has been separated by TLC (1801) and thin-layer electrophoresis (19). Nicotinic acid and nicotinamide have been separated by TLC and estimated quantitatively by in situ fluorometry (412) and spot size (1556). Thiamine, V'-methylnicotinamide, and related compounds have been separated by TLC (1628); N-(hydroxy methyl) nicotinamide and derivative have been separated by paper chromatography (588).…”

“…Nicotinamide was selected in a later investigation 288 for a comparison study of calibration curves obtained by fluorimetry, reflectance spectroscopy, and fluorescence quenching. For UV reflectance and for quenching methods the same shape of calibration curves was obtained, thus supporting the assumption that both methods work on the basis of UV absorption of the compound of interest.…”
