Germanane nanosheet as a novel biosensor for liver cirrhosis based on adsorption of biomarker volatiles - A DFT study
The present report investigates the geometric stability and electronic properties of germanane nanosheet, which shows a semiconductor nature. The germanane nanosheet is used as the base material for adsorption of liver cirrhosis biomarker namely methanol, 2-pentanone and limonene. The structural configuration, binding sites, charge transfer, variation in the energy gap along with adsorption energy are systematically explored. In addition, we investigated the energy band structure and density of states spectrum upon adsorption of liver cirrhosis biomarkers on germanane nanosheet. The present report lays the road for the possible application of monolayer material, namely germanane sheet, which shows excellent response towards liver cirrhosis biomarker volatiles. We suggest that the next generation nanosensors for detection of liver cirrhosis biomarker with high sensitivity material like germanane nanosheet.
