A system for generating an image of ultrastructural biomarkers from a biological sample is provided. The system includes a grid onto which a sample to be imaged may be placed and a cryogenic reservoir into which the grid and sample may be immersed for vitrification of the sample. The system also includes a stage onto which the grid and sample may be situated for subsequent imaging in a high contrast imager to permit identification of ultrastructural biomarkers therein. A method for generating an image of ultrastructural biomarkers from a biological sample is also provided. The generated image of ultrastructural biomarkers may be used subsequently for screening and monitoring diseases, evaluating drug and therapeutic efficacy, and assessing risks associated with a drug or therapeutic candidate, among other things.
