  • Sensing elements comprising gold nanoparticle-grafted carbon black
    Patent number: 11788985
    Abstract: Some embodiments presented here relate to chemical sensors with enhanced sensitivity and selectivity. In an embodiment, the sensor is a composite thin film that comprises (e.g., is made of) chemically-modified carbon black and a chemically-sensitive polymer base. By grafting gold nanoparticles on carbon black, the number of binding sites on the sensor thin film is increased, thereby increasing the sensitivity. Furthermore, ligand attached gold nanoparticles are grafted on carbon black to increase the binding sites on the sensor thin film in some embodiments, which results in increased sensitivity as well as improved selectivity in some cases.
    Type: Grant
    Filed: February 7, 2019
    Date of Patent: October 17, 2023
    Assignee: Stratuscent Inc.
    Inventors: Nicolas Levaray, Jayan Ozhikandathil, Ashok Prabhu Masilamani, Tullio Panarello

  • Methods for fabricating morphologically transformed nano-structures (MTNS) and tunable nanocomposite polymer materials, and devices using such materials
    Patent number: 10345234
    Abstract: In order to implement a microfluidics sensor having higher efficiency, Applicants have developed a method of formation of nano-structures having various shapes and sizes onto materials such as polymers, glass and silicon, which are compatible with the microfabrication processes. The adhesion of the nano-structures and feasibility to tune their properties (optical, electrical and mechanical) are two prime concerns when they are adopted for microfluidics devices.
