“…This observation could be explained in terms of restricted movement of lipases due to conformational binding on PS globules. For the immobilized enzymes, relatively higher temperature was required to achieve maximum relative activity [36]. It was also seen that with the increase in temperature (beyond 30 • C), the residual activity of immobilized lipase increased with respect to free lipase.…”

“…Poly(HEMA-MAT) nanostructures were prepared by surfactant-free emulsion polymerization as reported in our previous reports [37,38]. A typical polymerization procedure may be summarized as follows: Polyvinyl alcohol (PVA) (0.5 g) used as a stabilizer was dissolved in 50 mL deionized water to prepare the continuous phase.…”

Ö ZB u çalışmanın amacı, bir seri kesikli sistem deneylerle poli (hidroksietil metakrilat-metakriloil-(L) -triptofan metil ester) poli (HEMA-MAT)] nano-yapılarının yenilebilir bitkilerden serotonin için özütleme performansını değerlendirmektir. Polidispersiyon indeksi 1.189 olan nanoyapıların ortalama boyutu, zeta boyut analizi sonuçlarına göre 100 nmdir. Nanoyapıların maksimum serotonin adsorpsiyon kapasitesi, pH 6.0'da 2901.4±65.9 mg/g olarak bulunmuştur. Bu nanosorbentin, HPLC analizi öncesi muz ve domatesde serotonin özütlemesi için uygulanabilirliği de araştırılmış. Serotonin seviyesi muz için 86.26 mg/g, domates numuneleri için 36.02 mg/g olarak tespit edilmiştir. Anahtar KelimelerSerotonin, afinite nanosorbent, özütleme, hidrofobik etkileşim kromatografisi. A B S T R A C TT he aim of this study was to evaluate the extraction performance of poly(hydroxyethyl methacry-latemethacryloyl-(L)-tryptophan methyl ester) poly(HEMA-MAT)] nanostructures for serotonin from edible plants by a series of batch experiments. Average size of nanostructures was found as 100 nm with poly-dispersity index of 1.189 using zeta size analysis results. Maximum serotonin uptake capacity of the nanostructures was found to be 2901.4±65.9 mg/g at pH 6.0. Applicability of this nanosorbent for the extraction of serotonin in banana and tomato before HPLC analysis was also studied and the level of serotonin was determined as 86.26 mg/g for banana and 36.02 mg/g for tomato samples.

In this work, poly(HEMA-MAPA) membranes were prepared by UV-polymerization technique. These membranes were characterized by SEM, FTIR, and swelling studies. Synthesized membranes had high porous structure. These membranes were used for controlled release of curcumin which is already used as folk remedy and used as drug for some certain diseases and cancers. Curcumin release was investigated for various pHs and temperatures. Optimum drug release yield was found to be as 70% at pH 7.4 and 37 °C within 2 h period. Time-depended release of curcumin was also investigated and its slow release from the membrane demonstrated within 48 h.
