Technology Highlights

• The invention provides an alternative to a laboratory-based method which is expensive, slow, centralized, complex, inaccurate and require highly qualified personnel.
• The invention is a portable device providing an easy, rapid, cheap, simple to use, and suitably accurate results.
• The invention uses an electrochemical methods combined with easy-to-use and disposable sample cartridges to accurately and quickly quantify at least the four main cannabinoid molecules associated with potency.
• The invention achieves quick and accurate test results by providing a streamlined test kit apparatus that requires minimal training to operate/use.
• The invention configuration is such that the container can safely store the potentially dangerous chemicals used in testing away from the user and then can be properly disposed of.
• The depth of insertion of the container is made recognizable to the user (e.g., by a cutaway in the receiver wall or by haptic and/or audible feedback such as a 'click'), such that the user can determine when the container is properly inserted.
• The invention contains a guiding features (i.e., one or more integral ridges, bumps, indentations, grooves, etc.) to ensure the container is properly aligned when inserted, providing a single smooth operation to the user. It also contains an another feature (i.e., one or more integral ridges, bumps, indentations, grooves, etc.) to control the orientation of the container so that it can only be inserted in one orientation to ensure proper electrical contact.
• The invention uses a single-use cartridge style container integrated in a test kit that does not require the extensive maintenance or technical knowledge.
• The invention allows for tests to be done in non-laboratory settings providing a rapid and an accurate results while minimizing contamination and footprint.
• The invention is a small, rapid, and cost-effective devices for performing for selective detection and accurate quantification of cannabinoids in liquid or gaseous samples with enhanced sensitivity and selectivity.
• The invention senses or detects by measuring a current, voltage, impedance, capacitance, resistance, or any other electrical property or value in a circuit that incorporates the sensor element and, as such, this change in properties can be used in resistive, impedimetric, voltammetric, spectroelectrochemical, potentiometric, or amperometric systems.
• The invention and the OFET chip system can incorporated in various devices for different uses, such as wearable badges, wall-mounted devices, built-in devices for containers or vessels, consumer vaping devices or similar accessories, filters, or Tillable cigarettes, which may be coupled with an analytical reader, or may be incorporated in any portable or fixed analytical equipment.
• The invention can be attached to any user interface suitable for visual representations (e.g., screens, lights, or words), audio representation (e.g., buzzers, chimes, or vibrational alarms), or data sets indicative of sensed characteristics for further analytical processing by one or more computing devices.
• The invention with OFET device forms a wearable battery-powered badge which activates when a law enforcement officers enter premises or approaches vehicles, providing a "yes/no" analysis for the presence of cannabinoids.
• The invention with the OFET device includes additional communications electronics enabling remote communications providing records of the date, time, and approximate location of positive detection of environmental cannabinoids. This allow monitoring and reporting the presence of cannabinoids in the air, in private or public venues where cannabis use is not permitted (e.g., public transport, non-smoking facilities, e.g., schools, hospitals, airplanes, etc.).
• The invention allow for quality control during cannabis production by placing the sensors into storage containers or vessels for detecting vaporized cannabinoids that occurs during storage (i.e., natural off-gassing due to volatized cannabinoids), or any parts of equipment along the supply chain. The invention determines the ratio of cannabinoids released from samples, as well as the quantity of cannabinoid released. This application would provide for ongoing quality control during any steps of a cannabis supply chain.
• The invention can be integrated into a suitable device forming a consumer vaping device (i.e., vaporizers or electronic cigarettes) or accessory (e.g., fillable air bag inlet) to provide a measure of amount and ratio of cannabinoids in vapor produced by the given vaping device. As material is vaporized, gases would flow past the exposed OFET chip or system and provide on-the-spot readings of cannabinoid content.
• The invention can be incorporated into a device in the form of a clinical vaping device (including a vape pen) to provide a metered dose of THC and/or CBD delivery in a selective and controlled manner.
