Emerging medical biotechnology typically exhibits a ‘dual-use’ nature, which, while promoting human well-being, concurrently presents potential risks of misuse or abuse, thereby posing significant threats. Globally, including in China, emerging medical biotechnology is developing rapidly. To understand the views and perspectives of Chinese scientists on dual-use concerns, this empirical study conducted semistructured qualitative interviews with researchers (n=14) from various specialties within the Chinese medical field, analysing their perspectives and ethical considerations regarding dual-use concerns. The findings of this study reveal a (...) spectrum of attitudes among interviewees towards the exploration and application of emerging medical biotechnology, ranging from aggressive to conservative. This tension reflects the complexity and challenges of seeking a balance between promoting scientific innovation and maintaining ethical boundaries. Furthermore, while there is a consensus among scientists that the development and application of biotechnology encompass both risks and benefits, their stances on weighing these factors differ, reflecting how risk perception is influenced by professional limitations. Moreover, although scientists recognise the indispensability of both self-regulation and external oversight in practice, they also exhibit misunderstandings in ethical cognition and misinterpretations of regulatory measures. In light of these findings, it is imperative for us to urgently fortify national regulatory mechanisms and the construction of legal and ethical frameworks while also enhancing the ethical awareness and risk assessment capabilities of researchers. These measures are crucial for minimising the potential risks associated with dual use and fostering the sustainable and responsible development of emerging medical biotechnology. (shrink)
