International journal of Nano Scientific Networks and Nanotechnology (IJNN) is a multidisciplinary, peer reviewed journal which includes all the major fields in nanotechnology and Nano science. Nanoscience and nanotechnology brought up an unprecedented excitement in the scientific and engineering communities, especially the last decade. It is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.  International journal of Nano Scientific Networks and Nanotechnology   publishes original research papers during a broad area of nanoscience & engineering. IJNN provides an ideal forum for presenting original reports of theoretical and experimental nanoscience and nanotechnology research. Nanotechnology is a gathering of rising innovations in which the structure of matter is controlled at the nanometer scale, the size of little quantities of molecules, to create novel materials and gadgets that have valuable and one of kind properties. IJNN is naturally multidisciplinary, and welcomes submissions across biological, physical, engineering, and computer sciences. Contributions from both academia and industry are equally encouraged. IJNN also publishes innovative techniques and instrumentation for the fabrication, characterization and testing of nano-enabled devices and technologies, as well as advanced modelling and simulation methods.




WANG Zheng Ming


Dr WANG is a scientist working at Veterinary Public Health Centre, Singapore. He received his medical training (1981) in Shanghai, China; then Master’s degree (1992) and PhD degree (1998) in Physiology Department and Pathology Department, Medical School, Melbourne University respectively. During his PhD training period, he focused the research in mammalian development biology, dissecting the role of the mammalian Son of sevenless 1 (Sosl) protein in growth factor signaling in vivo by generating mice and cell lines that lacked the Sosl protein. Homozygous null embryos were smaller than normal, died mid-gestation with cardiovascular and yolk sac defects, and their fibroblasts showed reduced mitogen-activated protein kinase activation in response to epidermal growth factor (EGF). An intercross of mice mutant for Sosl and the EGF receptor (EGFR) demonstrated that a heterozygous mutation in Sosl dominantly enhanced the phenotype of a weak allele of the EGFR allele (wa-2). These animals had distinctive eye defects that closely resembled those seen in mice that were null for the EGFR or its ligand, TGFa. His findings provide the first demonstration of a functional requirement for Sosl in growth factor signaling in vivo. The results also show that the genetic test of enhancement of weak receptor allele by heterozygous mutation in one component represents a powerful tool for analyzing the ras pathway in mammals.

From 1998 to 2005, Dr WANG moved to Singapore, worked in Institute of Molecular & Cell Biology (IMCB) for 4 years, then in Medical School, National University of Singapore for 4 years respectively. During these times, Dr WANG’s research focus were on stem cell biology.

Dr WANG has joined Veterinary Public Health Centre, Singapore since 2005 where he is currently held a position of scientist. Dr WANG’s research field and interests are in emergent risk and risk assessment in agriculture and food sector. His works have covered from Genetically Modified Organism, to nanotechnology in agriculture and food production.
