Synthesis, Characterization and Chromatographic Applications of Antimicrobial Cryogels

Abstract

Ö ZP atojenik bakterilerin sebebiyet verdiği hastalıklara karşı antibakteriyel malzemeler son yılllarda olduça önemli bir ilgi merkezi haline gelmiştir. Bu çalışma kapsamında antimikrobiyal poli(2-hidroksietil metakrilat-glisidil metakrilat), pol(HEMA-GMA), kriyojeller sentezlenmiş ve yapıya L-Arjinin aminoasidi üzerinden Ag(I) iyonları immobilize edilmiştir. Yapının karakterizasyonu için; şişme testi, Frouer dönüşümlü infrared (FT-IR) spektroskopisi, taramalı elektron mikroskobu (SEM), yüzey alanı (BET), elementel ve ICP-OES analizleri yapılmıştır. L-Arjinin amino asidinden Ag(I) şelatlayıcı ligand olarak yararlanılmış ve kriyojellerin melittin proteini için adsorpsiyon kapasitesi 173.9 mg protein/g kriyojel olarak tespit edilmiştir. Anahtar KelimelerAntimikrobiyal, kriyojel, L-Arjinin, Ag(I). A B S T R A C TA ntibacterial materials, in the last years, have become an important center of attention against diseases because of pathogenic bacteria. Within the scope of this study, antimicrobial poly(2-hydroxyethyl methacrylateglycidyl methacrylate), poly(HEMA-GMA), cryogels were synthesized and Ag(I) ions were immobilized to the structure through the amino acid L-Arginine. For characterization of the structure; swelling test, Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), surface area (BET), elemental analysis and ICP-OES methods were performed. The L-Arginine amino acid was used as an Ag (I) chelating ligand and the melittin protein adsorption capacity of cryogels was determined as 173.9 mg/g cryogel.

Antibiotic Removal from the Aquatic Environment with Activated Carbon Produced from Pumpkin Seeds

“…The porous nature of construction is considered a critical advantage for adsorption [30][31][32][33][34], since the target molecule's attachment to and its retention in When the adsorbent's SEM analysis is examined, it is particularly striking that it has a porous structure (Figure 2). The porous nature of construction is considered a critical advantage for adsorption [30][31][32][33][34], since the target molecule's attachment to and its retention in the pore during interaction can be interpreted as a characteristic that facilitates adsorption. In addition, the fact that the adsorbed molecule is desorbed from the surface by various external factors complicates interactions within the pore.…”

“…When the SEM analysis of the adsorbent is examined, it is particularly striking that it has a porous structure (Figure 2). The porous structure of construction is considered an essential advantage for adsorption [28][29][30][31][32]. Elemental analysis results of the adsorbent are given in Table 1.…”

“…The heavy metals could accumulate in food chains and endanger public health. − Therefore, solving the problem of heavy metal pollution in the environment has always been a focus for researchers. Currently, various measures have been employed to solve this problem, such as chemical precipitation, ion exchange, membrane separation, adsorption, etc. , The adsorption method has been considered as the most widespread technology due to its flexible adsorbent design, easy operation, and high adsorption efficiency. − …”
