The polymerase chain reaction (PCR) tests for COVID-19 will be free of charge from May 1 to June 30, Shanghai government announced on Thursday.The measure aims to relieve the financial pressure on both residents and enterprises, according to Shanghai Fabu, the official WeChat account of Shan...
Efforts to mitigate the COVID-19 crisis revealed that fast, accurate, and scalable testing is crucial for curbing the current impact and that of future pandemics. We propose an optical method for directly imaging unlabeled viral particles and using deep learning for detection and classification. An...

CovidVHH-IgG production and secretion, NCYC 2543 produced reduced yields compared with thehoc1trstrains (Fig.5a). However, we observed two classes of production levels, raising the question of copy number effect. We determined that single-copy insertions resulted in higher CovidVHH-IgG production...
Results We tested the utility of cfDNA to quantify cell-, tissue-, and organ-specific injury associated with COVID-19 in two independent patient cohorts from two different hospitals in North America (Figure 1A, patient characteristics in Tables S1 and S2). We assayed a total of 104 plasma sa...
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is commonly diagnosed by reverse transcription polymerase chain reaction (RT-PCR) to detect viral RNA in patient samples, but RNA extraction constitutes a majorbottleneck in current testing...
Antibodies have also recently garnered attention as potential countermeasures for emerging pathogens, having been used as both prophylaxis and therapy against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus and cor- onavirus disease 2019 (COVID-19)6.
