This research presents a groundbreaking approach in virus-related research, addressing poison open up and say ahh t shirt challenges in electron microscopy (EM).This imaging technique has been crucial in exploring virus structures; however, traditional methods involve complex sample preparations and the risk of contamination.Herein, we introduce an approach that overcomes these obstacles, enabling high-resolution virus imaging without toxic staining procedures.Focusing on Begomovirus particles, an economically significant plant virus genus, our images confirm their non-enveloped structure and their twin icosahedral symmetry.Our methods involve sample collection, purification, and crystallization, followed by transmission electron microscopy - selected area electron diffraction (TEM-SAED) analysis.

Notably, this study achieves 2D and 3D virus imaging through standard TEM, providing a new avenue for hydrangea red sensation virus structure analysis and advancing virus-related research.Remarkable high image quality stemmed from the crystallization process, offering exciting possibilities for improving virus research and diagnosis while eliminating staining limitations.
