Trends in nano-inspired biosensors for plants

Nano inspired biosensors have acquired a vital part in improving the quality of life through various clinical, environmental, and quality-controlled applications throughout the world. Various nano-inspired biosensors have been reported that range from detection of plant infections (fungal, viral and bacterial), abiotic stress, metabolic content, phytohormones, mi RNAs, genetically modified (GM) plants to transcriptional and genetically encoded biosensors in very short span of time. Already, these nano-inspired plant biosensors are shown to be customized or ‘nano-tuned’ using various properties of nano-materials to combat various challenges of contemporary methods and achieve unprecedented levels performance (sensing ultra trace amounts) for in vitro and in vivo measurements reaching ‘Next Gen Nano inspired Biosensors’. Having been through with recent literature, existing tools and technologies (such as molecular imprinted polymers, microfluidics, plamonic nanosensors, Surface Enhanced Raman Scattering (SERS), fluorescence, chemiluminescence, quartz crystal microbalance, advanced electrochemical measurements) coupled with customizable nano-materials or nano-composites, potential niche has been lately realized and is being tapped to fabricate Nano-Inspired Plant Biosensors. Although, plant biosensors based research has gained impetus only very recently, there are fewer research findings available. Additionally, potential demonstration of Nano-Inspired Biosensors for non-plant applications do not limit plant biosensors to back foot in the presence, of contemporary techniques or ‘Transcriptomic Biosensors’, ‘Genetically Encoded Biosensors’ and Chimeric Biosensing technologies.
