Abstract
The C-type asteroid Ryugu samples returned by the Hayabusa2 spacecraft are the chemically most pristine material in the Solar System, as they have not been exposed to terrestrial environments. The organic matter in Ryugu records the molecular evolution from the Sun’s parent molecular cloud chemistry to asteroidal aqueous alteration. In this article, we review the results of Ryugu sample analysis and discuss the evolution of organic matter in the early Solar System by comparing these results with recent radio and infrared observations of protostars and protoplanetary disks.
期刊介绍：
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
