项目摘要

The need for technologies with the ability to reliably detect and respond to the presence of molecular agents is now more pressing than ever. Humankind has developed and relied on technologies capable of identifying cues associated to disease pathways, as well for the timely identification of allergens, and even for pinpointing the presence of pollutants. In particular, the current global situation has highlighted the importance of rapid and low-cost viral detection devices with the ability to help in managing public health threats. Biological systems have evolved over billions of years to reliably perform these tasks. I thus propose to use them as an inspiration to develop an innovative platform for sensing. By borrowing tools from physics, chemistry, and bioengineering, I will create artificial cells, bio-inspired systems constructed from elementary molecular constituents, with the ability to identify and respond to the presence of viruses. For this purpose, I will engineer responsive architectures with synthetic DNA molecules, dubbed DNA receptors, which can detect environmental "messages" and trigger a response in the synthetic cells. With such a strategy, I will develop a technology capable of identifying the presence of viruses and initiate responses to neutralise them and inhibit viral infection. Therefore, it is likely to find application in the clinical realm for smart diagnosis and therapeutics, as synthetic compartments with immune-cell functionalities.

现在比以往任何时候都更加迫切需要能够可靠地检测和应对分子制剂存在的技术。人类已经开发并依赖于能够识别与疾病途径相关的线索的技术，以及及时识别过敏原，甚至精确定位污染物的存在。特别是，当前的全球形势突出了快速和低成本病毒检测设备的重要性，这些设备能够帮助管理公共卫生威胁。生物系统已经进化了数十亿年，以可靠地执行这些任务。因此，我建议将它们作为开发传感创新平台的灵感。通过借用物理，化学和生物工程的工具，我将创建人工细胞，从基本分子成分构建的生物启发系统，具有识别和响应病毒存在的能力。为此，我将设计具有合成DNA分子的响应架构，称为DNA受体，它可以检测环境“信息”并在合成细胞中引发反应。有了这样的策略，我将开发一种技术，能够识别病毒的存在，并启动反应，以中和它们，抑制病毒感染。因此，它很可能在临床领域中应用于智能诊断和治疗，作为具有免疫细胞功能的合成隔室。
