Note: Many types of nano-sensors are designed using nano-structures for nano-biological applications. (Conductive surface) The oxidation of conductive polymer nanostructures is easily altered by redox mechanisms, and the charge transfer properties of these nanostructures are affected by structural parameters, such as diameter and dimensions.
Nanostructures Nano Structure are able to provide sensitive and rapid responses to specific biological and chemical species. Techniques such as chemical polymerization are often used to make nanostructures . Manufacturing strategies can be divided into three categories: synthesis using hard mold, synthesis using soft mold, and synthesis without mold. The most widely used conductive polymers used in nano-biosensors, nanomaterials made from nanostructures are used in various nano-biosensors due to their unique chemical and electrical properties due to the properties of their pie-electron nanosystem. they take.
How to functionalize nanostructures to make nanosensors
Many modeling and functionalization technologies are being developed to control the location, distribution, quantity, or structure and orientation of biological nanomolecules at the nanostructure level . Therefore, our level of contact between biological nanomolecules and nanostructures is of particular importance in numerous applications. Covalent and non-covalent modifications are two general methods for coupling biological molecules and nanostructures . Covalent functionalization is a chemical process in which there is a strong bond between nanostructures And its biological or relational molecules are formed. In many cases, surface chemical modifications are required to create active groups that can bind to biomolecules. Unlike covalent functionalization, in the non-covalent method, nanomolecules can be removed without destroying the geometric and electronic structure on the surface. Nanostructures are formed. Non-covalent interactions are of particular importance in many biological systems.
Conclusion :
The large surface-to-volume ratio in nanostructures and the high signal amplification potential provide ideal conditions for marking and detecting biological elements in the structure of nanosensors.
