Creative compliance and selective visibility: How Chinese queer uploaders performing identities on the Douyin platform

The growth in video-sharing social media platform use has changed modes of communication, which has helped to improve the visibility of gender and sexual minority groups. This tendency became evident given the social distancing during the COVID-19 pandemic. Likewise, the use of these platforms empowers LGBTQ individuals living in China to share knowledge and experiences, receive social and emotional support and so on. Previous studies rarely interrogate Chinese queer groups' socially sanctioned performance of identities on popular video-sharing platforms such as Douyin. This article undertakes a preliminary discussion of that research gap. It examines the conditions that enable such activities and concludes with a discussion of the strategies and methods that Chinese queer uploaders use in the process. Simply put, this article explores how the queer uploaders accommodate and negotiate their identity performances within a heterosexual and mainstream popular social media environment.

Paper-based netlike rolling circle amplification (NRCA) for ultrasensitive and visual detection of SARS-CoV-2.

COVID-19 is a highly diffuse respiratory infection caused by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). Currently, quantitative real-time polymerase chain reaction (qRT-PCR) technology is commonly used in clinical diagnosis of COVID-19. However, this method is time-consuming and labor-intensive, which is limited in clinical application. Here, we propose a new method for the ultrasensitive and visual detection of SARS-CoV-2 viral nucleic acid. The assay integrates with a paper device and highly efficient isothermal amplification technology - Netlike rolling circle amplification (NRCA), which can reach a limit of detection of 4.12 aM. The paper-based NRCA owns advantages of specificity, portability, visualization and low-cost. Therefore, this method can effectively meet the requirements of point-of-care testing, providing a novel molecular detection technology for clinical diagnosis of COVID-19 and promoting the development of NRCA devices.
