What are aptamers?
Aptamers are short, single-stranded DNA or RNA molecules that can bind to specific targets, such as proteins or viruses.
How does this protocol improve virus detection?
It allows for the selection of aptamers that specifically bind to infectious viruses, enhancing specificity and reliability.
Can this method be used for emerging viruses?
Yes, the protocol does not require prior knowledge of the virus's structure or sequence, making it applicable to emerging viruses.
What is the significance of monitoring disinfection methods?
Monitoring disinfection methods ensures that they are effective in rendering viruses non-infectious, which is crucial for public health.
Who demonstrated the procedure?
The procedure was demonstrated by Marcos Gramajo, a graduate student from the lab.
