Dear Muqsit Minhaj Pirzada , plenty of them have been used for sensing viruses (or their constituent parts). Please, may be you find the following review of interest:

Article Application of carbon nanomaterials in human virus detection

It is dealing with human virus, but can be generalised.

Hope it helps.

Dear @manuel i did go through this paper but it's about biosensing . I am looking for literature on bioimaging exclusively

Dear Muqsit Minhaj Pirzada , most of these biosensing applications can be adapted for bioimaging, in fact, the article shows some AFM image of virus over graphene. If you are looking for optical bioimaging, most -if not all- carbon allotropes have been used, but probably the most abundant bibliography corresponds to carbon quantum dots, which can be used in different fluorescence microscopies.

Here you can see some reviews:

Article Carbon “quantum” dots for optical bioimaging

Article Advances in fluorescent carbon dots for biomedical applications

Carbon nanotubes are also useful for biomaging:

Hope these articles help you.

Best!
