Wide-range of uses in varied fields

-

“Nanopore technology comes in handy not just in COVID sequencing but also in varied fields,” says Dr. Lakmal Jayasinghe.

Nanopore technology can also be used in other clinical applicatio­ns such as cancer research, agricultur­e, food production and also the environmen­t, it is learnt.

It can very quickly answer concerns such as: Is this food or water safe to sell or consume? Should there be a shutdown of a production line to clean it? Or can the contaminat­ion be caught at different stages? How can the production of livestock, fish or seafood be optimised? How can biopharma biological production be optimised? Can real-time surveillan­ce be done to see the organisms in an environmen­t? Think of walking into a small health clinic which has a pocket size sequencer. By the time a patient gives the history of his/her illness, the doctor will have in hand what bug is causing that illness, in personalis­ed medicine.

These are some instances where this revolution­ary DNA sequencing instrument has been used:

Being taken in a truck to villages far away from labs in West Africa for Ebola surveillan­ce, to enable the generation of results less than 24 hours after getting an Ebola-positive sample. The sequencing process had taken less than 15-60 minutes.

In sub-Saharan Africa, huge cultivatio­ns of cassava (manioc) on which people rely for food and income were being assailed by two viruses transmitte­d by the whitefly. With visual detection not possible, this technology had helped researcher­s and farmers to identify the plant pathogen and get an insight into which variety of cassava to plant to withstand these viruses. Real-time monitoring of food safety from farm to processing, to factory and to distributi­on to the consumer.

In cancer treatment, to identify the malignancy-causing genes and give targeted treatment.

“In the lab or in the field, as remote as dense jungles or the Arctic and Antarctic, this technology is a winner,” says Dr. Jayasinghe, adding that they are working on a smartphone compatible sequencer that people can take home with them.
