An Electronic Lab Notebook (ELN) is a digital version of the traditional paper lab notebook used by scientists and researchers to record experimental procedures, data, and observations. It serves as a collaborative platform, allowing multiple users to access, share, and collaborate on research findings in real time. ELNs find applications across various scientific disciplines, including chemistry, biology, physics, and engineering. They streamline data organization, facilitate efficient collaboration, and enhance data integrity by providing version control and electronic signatures. ELNs also support compliance with regulatory standards and reduce the risk of data loss or damage associated with paper notebooks.
