Hi There,

I am sure you have heard about Nano technology, whereby technology is merged with Science to create miracles in all respective field right from Automobiles to medicines to Agriculture

Speaking about Nano Biotechnology, it is basically where biology meets technology.
As you know Biotechnology is a field whereby Science helps creating instruments required for biological purposes or interventions.

As such speaking of biology, it is being used in may subfields right from Medicines to genes to molecular Sciences etc.

Thus Nano Biotechnology consists of a Research in these fields whereby scientists through Research helps in developing interventions in these fields.
Basically applying Nanotools to these fields and bring out interventions in the medical or biology field.
eg.drug delivery system and or Gene Therapy are a part of Nano biotechnology.

Please note this is a complete Research oriented field.

As far as the scope is concerned, these days as everything is becoming quick and fast paced and at the same time becoming smaller and smaller and due to the advance in the medical field, Research in this field is gaining momentum daily.

Right from the CT scan machine to the Pacemaker to finding root cause through understanding of the genes, finding solutions to sickness and other human issues through molecular study is all a thanks to Research in Nano Biotechnology.
So definitely you have scope in any industry right from Hospitals to laboratories, to Multi nationals to Pharma companies.
Hope this helps.
Wish you good luck...
