FoodDetective is first ever household biosensor that applies ultrasensitive ECL technology for detection of such food-borne harmful substances. It is highly sensitive with electrochemical signals, extremely convenient with detection results directly connected to mobile device, and reliefs families’ food safety concerns. The innovation is a portable, efficient, accurate, and easy-to-use biosensor invention that provides daily mediums for ensuring better food quality and resolves the inaccurate, high false-negative rate, inconvenient traditional methods. For customers, FoodDetective is the only choice in the market for high quality household detection of these harmful particles, and receives high popularity among mid-age, married customers with decent education level of undergraduate and above. In terms of business potential, a household viable product overruns commercial-setting biosensors that’s costly and unsuitable for personal usage and introduces top-notch technology into an underdeveloped market sector.
The most attracting innovation in our product is the ultrasensitive ECL technology. Before our design, food detectors in the market often use methods like digital insights and luminescence detection. These methods are either cost too much or lack accuracy. Thus, we developed a food-detective sensor that can solve above issues. Our detector faces ordinary families. Thus, our detector’s design goal is conveniency. The size of our product is 20*30*15cm, which is quite small and portable so that it is easy to be carried around. Also, the testing process is really easy. For operation, there are only two buttons available. By switching the opening between 1 and 2, people are able to detect different kinds of bacteria. The instructions are as follows: first, we need to insert Electrode piece; second, we need to switch modes for detection of metabolic toxin or pathogenic bacteria, and at last we need to transmit data to mobile device and analyze toxin concentration. The whole process takes no more than twenty minutes, which is convenient to operate. We used ultrasensitive ECL technology in our design. The ultrasensitive ECL technology is used to detect and quantify the presence and toxicity of specific neurotoxin based on an ECL signal. And the technology’s working principle is converting electrical energy into radiative energy. It involves the production of reactive intermediates from stable precursors at the surface of an electrode. These intermediates then react under a variety of conditions to form excited states that emit light. There are two advantages of using ECL technology, which are sensitive and stable. We developed our new machine based on the above advantages.
According to previous research, we found out that in the area of food safety pain points are inaccuracy of detecting and low efficiency. To resolve those pain points, we used ultrasensitive ECL technology to enhance our accuracy and efficiency. Our device can detect one kind of bacteria in 10-15 minutes. Also, we did some further exploration. Our device is able to detect several kinds of bacteria only by changing the mode, which is really convenient and satisfies people’s needs.
