Although PCR is highly sensitive, it has the disadvantage of requiring a large sample size and costly equipment. However, the development of micro electro-mechanical systems (MEMS) has made it possible for researchers to construct tiny devices. The microchannel`s high aspect ratio of surface to volume minimizes sample requirements and boosts the heating cycle rate, resulting in more efficient energy utilization. Nonetheless, microfluidic PCR still faces obstacles, such as the PCR heating source, the temperature distribution in the microchannel, and the simultaneous detection of numerous DNA sequences. Our team has previously exhibited systems using SPR sensors and microfluidic PCR that can identify DNA extracted from actual samples. However, this gadget is heated by a metal plate, limiting the device`s potential for volume reduction. To address the issue, this study focuses on developing a novel device using microfluidic photonic PCR and image surface plasmon resonance (image SPR). Introducing photonic PCR can reduce the size and energy consumption of the device. In addition, the SPR system can image PCR data, allowing for a greater detection limit, a lower signal-to-noise ratio, and a high throughput analysis. This device can perform rapid PCR thermocycling with light and concurrently detect numerous DNA fragments.光子聚合酶連鎖反應;影像化表面共振電漿;新型冠狀病毒;微流道;Photonic PCR; Image SPR; SARS-CoV-2; microchannel臺大與中研院聯合創新計畫【利用金屬奈米電漿子進行核酸擴增和即時定量之SARS-CoV-2檢測平台】
