Editorial
Yarman, Aysu; Lisdat, Fred; Wollenberger, Ulla (Elsevier BV, 2023)This special issue on biosensors and protein electrochemistry is dedicated to Professor Frieder W. Scheller on occasion of his 80th birthday in August 2022. Frieder Scheller’s contributions to the field of bioelectroc ... -
Electrochemical MIP sensor for butyrylcholinesterase
Özçelikay, Göksu; Kurbanoğlu, Sevinç; Zhang, Xiaorong; Söz, Çağla; Wollenberger, Ulla; Özkan, Sibel Ayşıl; Scheller, Frieder W. (Mdpi, 2019)Molecularly imprinted polymers (MIPs) mimic the binding sites of antibodies by substituting the amino acid-scaffold of proteins by synthetic polymers. In this work, the first MIP for the recognition of the diagnostically ... -
Electrochemical MIP-sensors for drugs
Yarman, Aysu; Kurbanoğlu, Sevinç; Jetzschmann, Katharina J.; Özkan, Sibel A.; Wollenberger, Ulla; Scheller, Frieder W. (Bentham Science Publ Ltd, 2018)In order to replace bio-macromolecules by stable synthetic materials in separation techniques and bioanalysis biomimetic receptors and catalysts have been developed: Functional monomers are polymerized together with the ... -
Electrochemical readout of molecularly imprinted polymers: potentials and challenges
Yarman, Aysu; Özçelikay, Göksu; Kurbanoğlu, Sevinç; Peng, Lei; Söz, Çağla; Özkan, Sibel Ayşıl; Wollenberger, Ulla; Scheller, Frieder W. (2020)Molecularly imprinted polymers (MIPs) are one of the most frequently studied alternative recognition elements in chromatography and sensorics. They are prepared by polymerizing the target analyte (socalled template) and ... -
Enzymes as tools in MIP-Sensors
Yarman, Aysu; Jetzschmann, Katharina J.; Neumann, Bettina; Zhang, Xiaorong; Wollenberger, Ulla; Cordin, Aude; Scheller, Frieder W. (Mdpi, 2017)Molecularly imprinted polymers (MIPs) have the potential to complement antibodies in bioanalysis, are more stable under harsh conditions, and are potentially cheaper to produce. However, the affinity and especially the ... -
How an ACE2 mimicking epitope-MIP nanofilm recognizes template-related peptides and the receptor binding domain of SARS-CoV-2
Zhang, Xiaorong; Waffo, Armel T.; Yarman, Aysu; Kovacs, Norbert; Bognar, Zsofia; Wollenberger, Ulla; El-Sherbiny, Ibrahim M.; Hassan, Rabeay Y. A.; Bier, Frank F.; Gyurcsanyi, Robert E; Zebger, Ingo; Scheller, Frieder W. (Royal Society of Chemistry, 2022)Here we aim to gain a mechanistic understanding of the formation of epitope-imprinted polymer nanofilms using a non-terminal peptide sequence, i.e. the peptide GFNCYFP (G485 to P491) of the SARS-CoV-2 receptor binding ... -
Insights in electrosynthesis, target binding, and stability of peptide-imprinted polymer nanofilms
Yarman, Aysu; Caserta, Giorgio; Gyurcsányi, Róbert E.; Wollenberger, Ulla; Zhang, Xiaorong; Zebger, Ingo; Supala, Eszter; Scheller, Frieder W. (2021)Molecularly imprinted polymer (MIP) nanofilms have been successfully implemented for the recognition of different target molecules: however, the underlying mechanistic details remained vague. This paper provides new ... -
Label-Free MIP sensors for protein biomarkers
Zhang, Xiaorong; Jetzschmann, Katharina; Yarman, Aysu; Scheller, Frieder W.; Wollenberger, Ulla (Springer, 2017)[Özet yok] -
“Out of pocket” protein binding—A dilemma of epitope imprinted polymers revealed for human hemoglobin
Zhang, Xiaorong; Caserta, Giorgio; Supala, Eszter; Wollenberger, Ulla; Gyurcsányi, Róbert E.; Zebger, Ingo; Scheller, Frieder W.; Yarman, Aysu (2021)The epitope imprinting approach applies exposed peptides as templates to synthesize Molecularly Imprinted Polymers (MIPs) for the recognition of the parent protein. While generally the template protein binding to such ...
