Nanomedicine and Sensors Session
The identification and the rapid detection of target analyte have been one of the most important issues for clinical diagnostic, environmental and food industry analysis. An ideal detection system should has an easy procedure to perform and a broad-range application with low detection limit, high sensitivity and high selectivity. Although variety of sensors have been used for characterization and even single molecule sensing, an optimal substrate for nanomedicine which is sensitive and reproducible is still a challenge. Micro- and nano- structured substrates have enabled detection of target analytes in real matrices. Successful detection by sensor systems is possible if the substrates are reproducible to detect target analytes. The design, preparation and surface modification of nanoparticles has the opportunity of effectively isolation of target from sample and obtaining the sensor signal related to target. The microfluidic systems will be a powerful alternative to the expensive conventional techniques that necessitate the consumption of excess amount of sample and materials. Especially, the microchip-based measurement would be a novel approach. From a general point of view, the analytical approaches, we would like to highlight through this session correspond to the expression of a strong need in terms of interdisciplinary research between basic science and engineering.
Nanomaterials and toxicity (Nanotoxicology) Session
Man-made nanomaterials and nanotechnology are widely used in many fields such as agricultural and food industry, personal care products, tissue engineering, pharmaceuticals, biomedical applications, drug and gene delivery, bio-detection of pathogens, and tumor therapy. So, nanomaterials may slip into our daily lives without our awareness. On a nanoscale, the features of nanomaterials can be very distinctive from those in bulk matter and display unusual physico-chemical characteristics such as smaller size, larger surface area, increased chemical reactivity, and easier entrance capacity into the cells. Such special properties of nanomaterials not only provide critical advantages for their preferences but also constitute toxicity because of their undesirable interactions with various types of cells and cellular processes. However, there is little research about how they affect human and ecosystem health. Therefore, in recent years, an increasing number of scientific research have been carried out on side effects of nanomaterials. Results showed both positive as well as negative effects. In this section, potential toxicity of nanomaterials (called as nanotoxicology) will be evaluated by various bioassays that are very important for the safe usage and applications of engineered nanomaterials in daily life.
