Now a days, increasing environmental pollution is the biggest issue worldwide because it is causing irretrievable damage to the earth. Therefore, it is imperative to develop robust sensors that can be used to assess the status of environmental conditions. In this regard, micro-nano materials with great physical and chemical characteristics are potential candidates to produce novel environmental monitoring sensors with good selectivity, sensitivity and stability. A variety of materials in their micro and nano forms such as metal organic frameworks, carbon nanotubes, graphite, metal nanoparticles and 2 D materials etc. are employed to develop different type of sensors with miniatured size that can be used in the field to monitor the quality of air, water and soil. These materials possess huge potential to replace the current monitoring techniques which are highly expensive and time consuming.

Suman Singh is working as senior scientist in CSIR-Central Scientific Instruments Organisation (CSIR-CSIO), Chandigarh, India and did her PhD from Panjab University, Chandigarh, India. She is also a faculty of chemistry and member of Welfare association at Academy of Scientific and Innovative Research (AcSIR) at CSIR-CSIO, Chandigarh. Her area of research work is advanced materials, nanotechnology and(bio)sensors. She is working on synthesis and application of molecularly imprinted polymers, low cost paper and lab-on-chip devices, nanomaterials and their composites for application in bio/chemo/immunosensing of analytes for applications like health, environment, and agriculture. She has been a regular recipient of funding from various agencies like DST-India, DBT-India, CSIR, ICMR. Her work is published in many reputed SCI journals and as book chapters to her credit.
