Synthetic cell membranes invented at the Institute of Materials Research and Engineering (IMRE), a research institute of Singapore’s Agency for Science, Technology and Research (A*STAR), may improve the way we identify and develop drugs by speeding up and reducing the cost of the drug screening process. The technology earned a spot as one of the twelve finalists in the Asian Innovation Awards 2011 organised by the Wall Street Journal Asia.
A membrane protein is directly produced and incorporated into the polymer membrane.
They may look and act like natural human cell membranes but the synthetic cell membranes invented by A*STAR’s IMRE have more advantages. IMRE’s patented synthetic cell membranes can be made-to-order, are easier to maintain in a laboratory environment and do not require the lengthy preparation that comes with working on live cell membranes. The synthetic cell membranes mimic the natural functions of cell membranes, such as interacting with drug molecules and antibodies, which is crucial in the drug discovery process. The innovation also provides a more stable membrane model for a better understanding of the mechanisms of diseases that affect human cells.
A team of researchers led by IMRE’s Dr Madhavan Nallani successfully used synthetic materials to mimic biological processes. “We have harnessed natural cellular processes to fabricate a simple yet functional system using engineered materials to mimic the cell membrane and its proteins,” said Dr Nallani, the IMRE scientist who invented the synthetic cell membranes. “These artificial cell membranes allow researchers to study interactions between membrane proteins, drugs and other compounds without the hassle of using living materials.”
“Cells communicate with each other through membrane proteins. The disruption of this communication mechanism causes diseases like cancer, diabetes and even Parkinson’s disease. Understanding the workings of membrane proteins is very crucial in creating medicines to combat these diseases,” explained Professor Eva Sinner, a visiting scientist at IMRE who works on biomaterials and is involved in the project.
Current methods of drug testing require living cells, which entail high capital and maintenance costs, as well as specialists to operate sophisticated equipment. IMRE’s patented synthetic cell membranes, which are essentially membrane proteins inserted into a stable polymer matrix outside a cellular environment, creates a platform for researchers to work on that both simple to use and easy to maintain.
“This innovation is a classic example of how materials R&D can be applied to biomedical technologies,” said Prof Andy Hor, Executive Director of IMRE. “The success of this technology will be a great boost in helping create better drugs faster and more cost effectively.”
Dr Nallani is currently looking for partners to commercialise the technology. The invention has direct impact and application in fields like drug discovery, antibody and therapeutics development, and drug delivery, which are collectively worth some US$170 billion dollars .Encl.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
