PolyU develops portable nucleic acid testing device for COVID-19 to enable fast and accurate results on-site

Over the past two years, the COVID-19 pandemic has imposed a tremendous impact on society as well as on the daily lives of individuals. In the “post-pandemic” era, it is important to strengthen efforts in research and development of drug and vaccine, while also continuing to uphold high standards of personal and environmental hygiene management. Therefore, an accurate and convenient COVID-19 testing method could certainly help ease the stress of post-pandemic life.   In 2020, an interdisciplinary research team from The Hong Kong Polytechnic University (PolyU) was awarded over HK$2.7 million by the Health and Medical Research Fund (HMRF) to commence research on a portable testing device for COVID-19 (the device). After one and a half years of extensive work, the team successfully achieved highly sensitive SARS-CoV-2 viral RNA detection based on the combination of reverse transcription–loop-mediated isothermal amplification (RT-LAMP) and gold nanoparticles (as amplification result readout reagent). The clinical sample test results were in full agreement with the reverse transcription–polymerase chain reaction (RT-PCR) standard.   The device accommodates up to six testing samples at one time. Excluding one positive and one negative control sample, up to four samples can be tested at the same time. Once the samples have been collected, tests can be run on-site using the device, without the need to return the samples to the laboratory.   The device provides a constant temperature of 65 degrees Celsius, and the built-in optical system will monitor the precipitation or dispersion of gold nanoparticles (precipitate in positive samples, while remain dispersed in negative samples). Real-time data will be sent to a mobile app via Bluetooth, and the test results will be analysed and displayed on the screen of the phone (image 2). An increase in the optical signal between 10 and 20 minutes indicates a positive sample, and the shorter the onset time, the higher the viral load in the sample. A positive sample can be confirmed in as short as 25 minutes. The entire test can be completed in about 40 minutes, and the test results can be recognised with bare eyes (image 3).   Professor Christopher CHAO, Vice President (Research and Innovation) of PolyU, was encouraged by the results of the research. He remarked, "We are grateful to the Food and Health Bureau for their trust in PolyU. With the strong support of the HMRF, PolyU is able to leverage its interdisciplinary strengths to contribute to the Government's anti-pandemic measures, and translate research outcomes into real-life applications, bringing about benefits to the community."   The lead of the research project, Professor YIP Shea-ping, Professor and Head of the Department of Health Technology and Informatics of PolyU, pointed out that “using gold nanoparticles as the amplification result readout reagent is the key to the success of this research. We are pleased to see that our method has attained excellent sensitivity and specificity, which is on par with the current PCR 'gold standard'.”   The portable and rechargeable design of the device enables the entire testing procedures to be performed outside the laboratory, right after on-site sample collection. Dr. LEE Ming-hung Thomas, Associate Professor and Associate Head of the Department of Biomedical Engineering of PolyU, is a key member of the research team. He explained, “Our team has conducted preliminary environmental sample testing using our gold nanoparticle-based RT-LAMP method, even without prior extraction and purification of nucleic acid. The time for running the test is shortened, and no large-sized laboratory equipment is required. Nucleic acid testing can be achieved in a handy device, and the accuracy is not affected even with low viral load. The next important step is to test with human unpurified samples directly.”   Dr. Lee added that both human and environmental samples can be tested in the newly invented device. Besides SARS-CoV-2, other viruses and bacteria can also be detected using this device (primers have to be redesigned). The unit cost of testing is comparatively lower than RT-PCR. Going forward, the team is planning to transfer the research outcomes to society by collaborating with industry players so as to extend the use of such technology to the wider community, in particular places where accurate results are needed within a short period of time (e.g. airports, quarantine facilities, elderly homes, clinics, ports, restaurants, shopping malls, schools, sports and recreational facilities, etc.). The team also hopes that with this invention in place, management of personal and environmental hygiene can be enhanced, and appropriate control measures can be implemented to reduce the risk of community infection.   ***END*** [From PolyU Media Release]   Related News Articles: 齊心抗疫 40分鐘完成 準確度「金標準」理大成功研發便攜式新冠病毒檢測儀  [AM730] 理大研發便攜新冠檢測儀 最快25分鐘知結果 [明報(Ming Pao Daily News)]

Monitoring medical conditions from inside the body with optical fibre microsensors

PolyU researchers have developed groundbreaking optical fibre microsensors which can be implanted into people’s bodies for medical applications.   Once used mainly for the transmission of data, fibre optics technology is increasingly being deployed in medical applications. Professor Tam Hwa-yaw, Chair Professor of Photonics and Head of PolyU’s Department of Electrical Engineering, has led a research team to develop novel fibre optic microsensors, which can be implanted into people’s bodies to enable more accurate medical surveillance for surgery and treatment.   The research team used an advanced plastic material, ZEONEX, to develop the microsensors, while they also added a ‘side hole’ inside the optical fibres to enhance their sensitivity. Named the “Side Hole Polymer Optical Fibre Sensors”, the microsensors are biocompatible, supple and extremely sensitive to very small pressure changes inside human bodies.   The new microsensors can be as small as a few micrometres. “Our microsensors can detect extremely subtle changes, even a difference smaller than 1% of atmospheric pressure. They are sensitive enough to measure pressure inside the lungs while someone is breathing,” Professor Tam said. He believes the breakthrough will enable the development of a whole new range of applications for medical monitoring inside people’s bodies.   Overcoming the drawbacks of existing optical fibres   Although optical fibres are increasingly being used in medical equipment, such as sensor-based wearable medical devices and surgical instrumentation, the existing glass optical fibres and the traditional plastic optical fibres have several drawbacks. The former is too stiff and brittle, while the latter may absorb water that can affect the operation of sensors.   The PolyU-developed microsensors overcome these challenges, enabling them to be implanted inside people’s bodies. Professor Tam explained: “The plastic material ZEONEX has low moisture absorption and high precision in molding. To enhance the sensitivity of the microsensors, we have also added a side hole running parallel with the light transmission path inside the optical fibre.”   “Therefore, the microsensors can be made as small as a few micrometres and their sensitivity to pressure is 20 times that of traditional optical fibre sensors,” he added.   Creating new possibilities for medical applications   As the microsensors are humidity insensitive, shatter-resistant, chemically inert and biocompatible, they can potentially be used for a broader range of medical applications.   Cochlear implantation with higher accuracy The PolyU research team, in collaboration with the University of Melbourne and Royal Victorian Eye and Ear Hospital in Australia, is incorporating tailored microsensors into cochlear implants, so that surgeons can obtain real-time information on the location and force response of the cochlear implant during surgery, thereby increasing the implant’s effectiveness.   Navigation monitoring in cardiac catheterisation With high shatter resistance and biocompatibility, the new optical fibres can be used for precise navigation and shape detection for minimally invasive surgical procedures.   Bone fracture recovery monitoring The PolyU research team is collaborating with Monash University in Australia to integrate the microsensors into orthopaedic implants for monitoring bone fracture recovery. The photo shows that the microsensors (fixed by yellow tapes) are placed near the fixed implant of the fractured area (middle) of the thigh bone.   The future of microsensors   The “Side Hole Polymer Optical Fibre Sensors” research findings were published in 2021 in US-based The Optical Society’s Optics Letters. Some of the applications jointly developed with other universities have already been granted patents.   Professor Tam and his team are now working to expand the sensors’ ability to measure other physical or chemical changes in the body, such as acidity and temperature.   “We are also seeking to develop a sensing network that integrates our sensors with emerging technologies like the wireless Internet of Things. The sensing network would be able to give a comprehensive and precise picture of changes inside the human body, thus helping patients around the world through technological innovation,” he said. By integrating the new microsensors with wireless Internet of Things, Professor Tam (middle) and research fellows, Dr Xin Cheng (left) and Dr Dinusha Serandi Gunawardena (right), aim to develop a sensing network that can provide a comprehensive and precise picture of changes inside human bodies.
