| Abstract | A method of manufacture of a device to monitor the flow rate of liquids comprising the steps of synthesizing the nanoparticles of gold, stabilized by citrate groups; pre-cleaning of the indium doped tin oxide conducting glass (ITO) by sonicating with deionised water; activating the surface of the substrate by soaking in 10% solution of HCI; washing the substrates with water followed by drying the same in oven at 100°C for 1 hour; annealing the same thereafter in a hot-air furnace at 450°C for 7 hours; cooling and drying the substrate in a desiccator; coating the substrates with a multilayer assembly of gold nanoparticles by dipping the substrate in a 3% solution of 3- aminopropyl triethoxy silane (anchor molecule) in 2-propanol for 2-5 minutes; heating the substrate at 110°C for 10 minutes to remove 2-propanol; cooling and drying the substrate in a desiccator; dipping the substrate in an aqueous solution of Au@citrate for 10-15 minutes; removing the substrate, washing with water; dipping in Au@citrate for 10-15 minutes; washing with water flowed by 2-propanol; dipping in a 2-propanolic solution of 1,6 hexanedithiol (spacer molecule) for 30 minutes. Dipping in Au@citrate and 1,6 hexanedithiol are repeated to achieve the desired number of layers; and finally dipping the substrate in the solution of the spacer molecule. |
