Summary: Since the global pandemic of SARS-CoV-2, the need for a low-cost and faster diagnostic tool for evaluating symptomatic patients has emerged. Point-of-care testing and point-of-need testing systems have been developed to provide accurate and rapid diagnostics. In this study, a bio-photonic device using an iso-thermal system was developed for detecting SARS-CoV-2. The device showed comparable sensitivity to the commercially used reference method and was built with simple and low-cost components, making it a high-efficiency and affordable instrument.

Summary: Genetic mutations like SNP are common in genetic disorders and cancers, and PCR methods are widely used for SNP detection. The specifically designed PCR platform STexS can efficiently distinguish small amounts of SNP mixed in normal DNA, aiding in targeting potential SNPs or genetically mutated biomarkers in human clinical samples.

Summary: Accurate detection and quantification tools for Toxoplasma gondii are valuable for the management of toxoplasmosis. This study evaluated the performance of droplet digital PCR (ddPCR) for T. gondii detection and quantification. The results showed that ddPCR had equivalent performance to qPCR for T. gondii detection and was more accurate for quantification.

Summary: This study aimed to determine the subjects for bacterial multiplex polymerase chain reaction (mPCR) testing and to interpret the mPCR test results based on patients' clinical symptoms and diagnoses. The study found that positive mPCR test results were significantly associated with older age, diagnosis of acute gastroenteritis, presence of hematochezia, and absence of cough. Additionally, the identification of invasive pathogens in patients with positive mPCR test results was significantly associated with the diagnosis of acute gastroenteritis, presence of fever and diarrhea, and higher C-reactive protein levels. Therefore, selective bacterial mPCR testing should be performed based on the patients' clinical symptoms and diagnoses.

Summary: In response to the need for rapid infectious pathogen detection, researchers have been working on adapting PCR for POC applications. This paper introduces a compact plasmonic PCR thermocycler for fast DNA amplification using photothermal heating with gold nanorods and a VCSEL. An ultrasensitive real-time amplicon detection strategy is also reported, based on monitoring UV absorption of the PCR sample cycle-by-cycle. This system allows for high detection sensitivity and does not require specific probes or fluorophores.

Summary: This study proposes a method to generate droplets in a cylindrical tube for emulsion polymerase chain reaction. The validity of a non-planar droplet chip is verified by analyzing the light intensity of liquids in real-time during droplet processing. The study also compares two digital droplet PCR methods for measuring the copy numbers of EGFR.
