Polime là những hợp chất có phân tử khối rất lớn do nhiều đơn vị nhỏ (gọi là mắt xích) liên kết với nhau | Presented By: Deepshikha Amity University Noida Objective Optimization of process parameters to find out the best nanostructured conducting polyaniline in terms of conductivity and size. Application of nanostructured conducting polyaniline to biosensors. Conducting Polymer A conductive polymer is an organic polymer semiconductor. They provide pathways for electronic conduction by doping. Common classes of organic conductive polymers include Poly(acetylene)s, Poly(pyrrole)s, Poly (thiophene)s, Poly(aniline)s etc. Characteristics of Nanostructured materials Nanostructures are inorganic, organic materials with one dimension down to the nanometer range . within 1-100 nm. Unique aspect of nanomaterials is the vastly increase ratio of surface area to volume Dramatic changes in properties (electrical, thermal, mechanical, electronic, optical) in nano scale dimension from their bulk material. Biosensor Bio sensor is an analytical device which converts a biological response into readable signal . Bio sensor comprises of three components: bioreceptor, transducer and detector. Advg of Nanostructured Conducting Polymers (NSCP) for Biosensor appl High Surface Area Unique optical, electronic and magnectic properties Bio-compatibility Dimensional compatibility with biomolecules. Film forming ability. Flexibility and processibility. Size, stability, morphology , conductivity and porosity of nanostructured conducting polymers(NSCP) can be modified by changing reaction conditions. Unique π electron uni-dimensional conductivity- enhancing the electron transfer rate(ETR) , lowering the detection potential and enhancing the stability of the enzyme . Electrochemical switching depending upon pH and state of oxidation. Polymerisation procedure Aniline was dissolved into SDA solution Temperature was maintained at 00 to 50C Oxidizing agent, (NH4)2S2O8, in ice-cold water was added Polymerisation was allowed to proceed for 3 to 4 h Mixture was allowed to age under static condition for 1-3 | Presented By: Deepshikha Amity University Noida Objective Optimization of process parameters to find out the best nanostructured conducting polyaniline in terms of conductivity and size.
