We will show that it is possible to build a portable platform capable of capturing viruses according to their size and thus enabling direct genomic sequencing in the field. I will discuss how aligned carbon nanotubes (A-CNT) on different substrates can be used as novel three-dimensional (3D) filters that are able to effectively trap viruses by size without labels (antibodies). We are able to tune the inter-tubular spacing from 20 to 500nm. This range covers more than 90% of known viral pathogens. A new technology using this CNT-device in conjunction with Raman spectroscopy and machine learning will be discussed. This platform in now able to identify human viruses with 90% accuracy.
