Journal Club of the week: Nano-materials based Bio-sensors in Toxicology Application


 

Date: 18th January

Speaker: Shokoufeh Hassani, PhDs 

Topic: Nano-materials based Bio-sensors in Toxicology Application

 

In the today journal meeting Ms S Hassani introduced the participants to nano-material and its use as bio-sensors for toxicological application. She described how nano-materials research takes a material science-based approach to nanotechnology, extensive advances in materials sciences and synthesis, which have been developed in support of micro-fabrication research. Materials with the structure at the nano-scale, often have unique optical, electronic, or mechanical properties. Inorganic nano-materials like quantum because of their interesting optical and electrical properties could be used in opto-electronics. In the second session of her presentation, she talked how the sensitive biological element (e.g. tissue, microorganisms, organelles, cell receptors, enzyme, antibodies, nucleic acid, etc.), a biologically derived material that interacts the analyze under study. The biologically sensitive elements can also be created by biological engineering. The transducer or the detector element (works in a physico-chemical way; optical, piezoelectric, electro-chemical, etc.) that transforms the signal resulting from the interaction of the analyst with the biological element into another signal (i.e., transducers) that can be more easily measured and quantified. Bio-sensor reader device with the associated electronics or signal processors that are primarily responsible for the display of the results in a user-friendly way. In the end she suggests that in near future simple, portable and self-reading bio-sensors will be marketed. However, safety guidelines and toxicity of nano-particles should not be underestimated. At the end all participants asked their valuable questions and she answered all the questions. Prof Abdollahi summarized whole topic and stressed how to make sure about the safety of nanomaterials.
