The rapid development of instrument and data processing technology, especially the invention of electron microscopy, has brought great help to obtain the ultrastructure of viral particles. Equipped with state-of-the-art optical microscopy, electron microscopy, and powerful data processing software, Creative Biostructure can provide visualization services for coronavirus-like particles based on a variety of technologies.
Coronaviruses (CoVs) have led to two major outbreaks of human fatal pneumonia since the beginning of the 21st century. The Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) broke out in 2003 and spread to five continents with a lethal rate of 10%. And the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) broke out in the Arabian Peninsula in 2012 with a lethal rate of 35%. SARS-CoV-2 (provisionally named 2019-nCoV) is a novel coronavirus that leads to an outbreak of respiratory illness termed as Coronavirus Disease 2019 (COVID-19), which has spread to many countries around the world.

With the assistant of instruments, we can easily obtain biophysical information of viral particles, which supports identification and characterization of virus in a directly visualized manner, as well as to screen important components during the viral infection process. At present, scientists have obtained several electron microscopic images of SARS-CoV-2 virions. Thanks to our professional structural biology technologies, Creative Biostructure can provide a variety of services based on electron microscopy and super-resolution optical microscopy, including but not limited to:
