Ab initio study of alkali-metal-decorated silicene for acetone sensing and trapping as a diabetes biomarker

Key Points

• Acetone sensing is greatly improved by alkali-metal decoration on silicene, enhancing sensitivity.
• The study shows nearly complete acetone adsorption on silicene with lithium and sodium at specific conditions.
• Ab initio calculations were utilized to assess the interaction between acetone and alkali-metal-decorated silicene.
• This technique suggests promising applications in developing biosensors for diabetes monitoring.
