Telecommunications giant Huawei is said to be one of the most powerful companies in China. But Huawei has been accused of systematic espionage, and some Western governments doubt whether the company is truly independent of the Chinese government.
This documentary investigates concerns about Huawei and internet security. The company is a major player in the manufacture of smartphones, and enjoys a technological lead in the development of the super-fast 5G broadband network worldwide. But the US and some other Western countries suspect that Huawei works closely with the Chinese government on espionage and sabotage operations.
Has Huawei becomne a pawn in the trade war between the US and China? The arrest of Huawei chief financial officer Meng Wanzhou in Canada in 2018 — at the request of US authorities — marked the climax of the conflict between Huawei and Washington. Some European countries also have concerns about the company.
Does Huawei really have close ties to the Chinese government? And what are the benefits and risks for those foreign clients who choose to work with this 5G giant?
The patented detection method detects minute fluorescence signals using unique fluorescent nanoparticles and a sophisticated reader system to achieve accurate results from a clinical sample, overcoming the sensitivity limitations of typical lateral flow technology. The key elements of Ellume’s digital technology reduce the probability of false results, create new pathways to treatment, and optimize secure public health reporting. These unique features are critical to the approval, success and adoption of self-administered home testing.
Supercharged fluorescent immunochromatography using a quantum-dot based fluorescent particle
The Ellume COVID-19 Home Test’s core technology combines ultra-sensitive optics, electronics and proprietary software to leverage best-in-class digital immunoassay technology with next-generation multi-quantum dot fluorescence technology.
How it works
Safe, accurate and rapid self-test
The test includes a sterile Nasal Swab, a Dropper, Processing Fluid, and a Bluetooth® connected Analyzer for use with an app on the user’s smartphone. Utilizing the dedicated app, the user follows step-by-step video instructions to perform the test including a self-collected mid-turbinate nasal swab. The sample is analyzed, and results are automatically transmitted to the user’s smartphone via Bluetooth® in 15 minutes or less. Results can be shared with healthcare professionals to enable optimal therapy.
Through a secure cloud connection, Ellume’s COVID-19 Home Test can provide real-time reporting of test results to health authorities, employers, and educators, for efficient COVID-19 mapping.
