Abstract
A sensor structure, and a method if using and manufacturing the sensor structure. The manufacture of the sensor structure may include the steps of providing a deposition solution in the pores of an anodic alumina membrane, distributing the deposition solution in the pores of the membrane, heating the membrane to evaporate the solvent and deposit the nano particles, cleaning the membrane and repeating the procedure until a predetermined size and distribution of the deposited nano particles is achieved.
Claims34
A method of manufacturing a permeable sensor structure, comprising the steps of:
- applying a deposition solution, that includes nanoparticles in a solvent, on a surface of a permeable anodic alumina membrane, the membrane including a plurality of pores each of which being defined by walls;
- allowing capillary forces to distribute the deposition solution in the pores of the membrane;
- and
- heating the membrane to evaporate the solvent and deposit the nanoparticles on the walls of each of the pores.
A sensor structure comprising a permeable porous anodic alumina membrane with sequentially deposited nanoparticles on pore walls of the membrane.
A method comprising the steps of:
- providing a permeable porous anodic alumina membrane with sequentially deposited nanoparticles on pore walls of the membrane;
- and
- using the membrane as a sensor for Surface Enhanced Raman Spectroscopy.
