The adsorption and preservation of amino acids by clay minerals will be studied using molecular dynamics simulations, to give insight into the preservation of potential biosignatures. An automated routing simulation sampling of interactions between amino acids and various Martian minerals under an array of environmental conditions will be performed, the results will be statistically analysed to infer the composition of a peptide that may be synthesised from adsorbed amino acids on the clay. This will allow us to identify proto-biosignatures from a real ones that may be found on Mars or other extraterrestrial bodies, using relatively simple instruments in-situ.

将使用分子动力学模拟研究粘土矿物质的吸附和保存，以深入了解潜在的生物签名。将在一系列环境条件下对氨基酸与各种火星矿物质之间相互作用的自动路由模拟采样，将对结果进行统计分析以推断肽的组成，这些肽可以从粘土上的吸附氨基酸中合成。这将使我们能够使用相对简单的仪器（现场）从火星或其他外星物体上发现的真实生物签名来鉴定可在火星或其他外星物体上发现的原始生物签名。
