AI-powered staining in microbiology: Researchers introduce virtual Gram staining of label-free bacteria

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria. This new technology uses artificial intelligence to convert microscopic images of unstained bacteria into their Gram-stained equivalents, bypassing the traditional chemical staining process. The findings are published in the journal Science Advances.
