چکیده
The research carried out in the laboratory of Dr. R. Jelinek aims at studying varied membrane processes and biotechnological application utilising an innovative chromatic lipid/polymer molecular assembly mimicking cellular membranes. Extensive experimental work carried out during the past few years has demonstrated that dramatic colour transitions can be induced within the polymer (polydiacetylene, abbreviated PDA) by diverse bio-molecular interactions at the membrane interface. The lipid/PDA assemblies were shown to exhibit wide-ranging scientific and biotechnological applications based upon the interconnection between the bio-mimetic platform [the lipid assembly] and the colorimetric reporter [the PDA domains]. Additional research efforts aim for studying effect of lipids upon fibrillation processes. Selected research projects:

Fabrication of Nanofiltration Membrane from Polysulfone Ultrafiltration Membrane Via Photo olymerization
UV-induced grafting technique was used as a flexible method for surface modification of Polysulfone (PSf) ultrafiltration (UF) membranes in order to prepare hydrophilic nanofiltration (NF) membranes. Flat sheet Polysulfone (PSf) ultrafiltration membranes were prepared via phase inversion method. N-methylene-2-pyrrolidone (NMP) and polyethylene glycol (PEG) of three different molecular weights (...
متن کاملA Novel Nanofiltration Membrane Prepared with PAMAM and Graphene oxide for Desalination
Nanofiltration is increasingly gaining attention in many separation and treatment processes such as water softening, color removal and separation of medicines. Nanofiltration membranes are often negatively charged, displaying separation characteristics in the intermediate range between reverse osmosis and ultrafiltration. In this research, a novel nanofiltration membrane prepared with poly(amid...
متن کاملSelf-assembly of biological membranes into 200-400 nm aqueous compartments.
Membrane formation by amphipathic mixtures in aqueous environments is central to eukaryotic biology. Formation of aqueous compartments enclosed by membranes is of immense importance in designing liposomal systems for pharmaceutical applications. It is also continuously controlled within the dynamic environment of a living cell and, during cell division. In spite of over four decades of research...
متن کاملCell-surface sensors for real-time probing of cellular environments.
The ability to explore cell signalling and cell-to-cell communication is essential for understanding cell biology and developing effective therapeutics. However, it is not yet possible to monitor the interaction of cells with their environments in real time. Here, we show that a fluorescent sensor attached to a cell membrane can detect signalling molecules in the cellular environment. The senso...
متن کاملCell membrane damage by iron nanoparticles: an invitro study
Application of nanotechnology in medicinal and biological fields has attracted a great interest in the recent yeras. In this paper the cell membrane leakage induced by iron nanoparticles (Fe-NP) against PC12 cell line which is known as a model of nervous system cell line was investigated by the lactate dehydrogenase (LDH) test. Therefore, PC12 cells were incubated with different concentration o...
