Head of researchers, Assoc. Prof. Dr. Fatimah Abu Bakar from the Institute of Bioscience, UPM said the technology provides a rapid and effective method in determining the level of formaldehyde, a chemical which can increase the risk of lung and brain cancer as well as leukaemia when consumed excessively.
“Despite the abusive usage of formaldehyde as preservatives in fish and fish products, there is still no standard and systematic monitoring procedures, hence with this technology we might be able to detect the use of prohibited chemical by the unscrupulous traders,” she informed the reporters at the UPM New Product press conference organized by the University’s Research Management Centre and the Corporate Communication Division.
She said the biosensor only takes 10 minutes to produce results as opposed to the conventional method, which normally took a day and it can be used at any location on land, moving transportation and also at the fish retailers.
The project kicked off in 2007 and finally completed this year with a filed patent and funded by the Ministry of Science and Technology, (MOSTI).
The research team was assisted by fellow researchers, Prof. Dato’ Dr. Abu Bakar Salleh, Deputy Vice Chancellor (Research and Innovation) of UPM, Assoc. Prof. Dr. Nor Azah Yusof (UPM), Nur Indang Marzuki (UPM) and Prof. Dr. Lee Yoke Heng (UKM).
““The retail price will be determined by the manufacturer but the approximate cost of producing the device is RM50 and it can be reused for 60 times,” she said as she expressed her hopes that this product will soon capture the interest of targeted buyers.
Formaldehyde is an important chemical used widely by industry to manufacture building materials and numerous household products and also used in hospital as preservatives for anatomical specimens. Embalming in fish using the formaldehyde will ensure the quality appearance of the fish and for prolonged freshness.

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....

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...
