Development of sensor for fluoride detection and defluoridation of drinking water
through Nano-Biotechnology approach
Suphiya Khan
Banasthali Vidyapith, India
Water scarcity is considered as a major crisis of the 21st
century. It is reported that in 2015 approximately 663
million people lack access to safe drinking water worldwide.
Fluoride (F) is a major contributor to the world water crisis
affecting about 200 million people worldwide. The rural
population is more prone to F contamination as in some
places, the available techniques are neither acquainted nor
affordable. The fluorosis is reported more prevalent in rural
population due to excess F contaminated water inevitably
consumed by the rural population. F is known to cause
mottled enamel, osteoporosis, crippling skeletal fluorosis,
kidney imbalance and in severe cases leading to mortality.
Several methods have been developed to efficiently remove
F from water including nanofiltration (NF), reverse osmosis
(RO), forward osmosis (FO), coagulation, ion exchange and
adsorption. The cost and effectiveness of the defluoridation
techniques are still not satisfactory and thus required further
improvements. My talk will cover mainly the development of
biosensor,colorimetricsensorandhybridhydrogelcomposites
for defluoridation technology that has been done in my lab.
Biosensors consist of abiological entity that canbe anenzyme,
antibody or nucleic acid that interactswith F and produces the
signal that is measured electronically. Other than this, highly
sensitive carbon quantum dots (CQDs) based colorimetric
detectors for F ions will be mentioned. It will also include the
3D graphene oxide-based hybrid hydrogel, CNT based novel
composites and NP-PUF pouches for F remediation from
drinking water. Along with this, nano-phytoremediation of F
by Prosopis juliflora through the application of Fe3 O4 NPs will
be discussed. Simultaneously, I will give you the insight about
our center activities and goals of “Center for Excellence on
Water and Energy” of Banasthali Vidyapith, Rajasthan, India.
Brief outline of my current going projects and future plan.
