项目摘要

The past decade has seen researchers in the field of bottom-up synthetic biology try to fill the gap between biology and chemistry to better understand how the non-living becomes alive. To do this, attempts have been made to construct what are called protocells. These are cell-like entities created from scratch using a toolbox of molecules, materials, and chemical reactions. The Gobbo Group (https://gobbo-group.com) aims to pioneer new research frontiers in bottom-up synthetic biology by developing the first experimental methodologies to organise millions of protocells into self-standing protocellular materials that are stable in water, highly modular, and engineered with specific internal architectures for information processing tasks. More specifically, the aim of this project is the implementation of the first protocellular material-based BioCHIP that can sense, process and respond to DNA signals received in input from the bulk solution. The student will tackle the following exciting challenges of BioCHIP design and synthetic construction: 1) the development of methodologies for the light-induced controlled release of DNA strands from protocell building blocks; 2) the study of how chemicals diffuse within a protocellular material; and 3) the implementation of logic bio-circuits within a protocellular material based on toehold-mediated DNA strand displacement.

在过去的十年里，自下而上合成生物学领域的研究人员试图填补生物学和化学之间的差距，以更好地理解非生命是如何变得有生命的。为了做到这一点，人们试图构建所谓的原始细胞。这些是使用分子，材料和化学反应工具箱从头开始创建的细胞状实体。Gobbo集团（https：gobbo-group.com）旨在通过开发第一种实验方法来开拓自下而上合成生物学的新研究前沿，将数百万个原始细胞组织成独立的原始细胞材料，这些材料在水中稳定，高度模块化，并设计有特定的内部结构用于信息处理任务。更具体地说，该项目的目的是实现第一个基于原始细胞材料的BioCHIP，该BioCHIP可以感知、处理和响应从本体溶液输入的DNA信号。学生将解决BioCHIP设计和合成构建的以下令人兴奋的挑战：1）光诱导控制释放DNA链的方法的开发从原细胞构建块; 2）化学物质如何在原细胞材料内扩散的研究;和3）基于支点介导的DNA链置换的原细胞材料内逻辑生物电路的实现。
