Scientists from the city-based Centre for Nano and Soft Matter Sciences (CeNS) have developed an electronic nose with biodegradable polymer and monomer that can detect hydrogen sulphide (
H2S).
H2S is a poisonous, corrosive and
flammable gas produced from swamps and sewers. H2S is the primary gas produced from the microbial breakdown of organic matter in the absence of oxygen, and this necessitates easy detection of its emission from
sewers and swamps.

Scientists from the Centre for Nano and Soft Matter Sciences (CeNS), Bangalore, have developed an electronic nose with biodegradable polymer and monomer that can detect hydrogen sulphide (H2S), a poisonous, corrosive, and flammable gas produced from swamps and sewers.
H2S is the primary gas produced from the microbial breakdown of organic matter in the absence of oxygen, and this necessitates easy detection of its emission from sewers and swamps, the Ministry of Science and Technology said in a statement.

The impersonation of ORN with the help of an organic electronic device consisting of biodegradable polymer and monomer under Dr. Channabasaveshwar
Yelamaggad from CeNS and Prof. Khaled N. Salama, Sensors lab, Advanced Membranes, and Porous Materials Center, King Abdullah University of Science and Technology (KAUST), Saudi Arabia has been published in the journals
‘Materials Horizon’ and
‘Advanced Electronic Materials’ recently.
The fabricated sensor consists of a heterostructure consisting of two layers – the top layer a monomer and is realized with a novel chemical tris (keto-hydrazone), which is both porous and contains H
2S specific functional groups, and the bottom layer is the active channel layer which plays a key role in altering the current and mobility of charge carriers.
