Researchers Develop Highly Efficient Imprinted Polymers for Capture of Environmental Carcinogens

Strategic Insights

— 1 min read

Researchers in Nagpur, India, have made a significant breakthrough in the development of imprinted polymers that can effectively capture environmental carcinogens, such as polycyclic aromatic hydrocarbons (PAHs). The study, conducted at the CSIR - National Environmental Engineering Research Institute, utilized atomic force microscopy (AFM) to investigate the binding properties of imprinted cavities in the nanofilms. The research has been peer-reviewed and published in the journal MRS Communications.

Key Takeaways:

  • The researchers developed imprinted polymers with template-specific cavities that can selectively capture PAHs from aqueous solutions.
  • AFM investigations revealed the geometrical features of the imprinted cavities in three-dimensional detail at the sub-micron level.
  • The binding properties of the imprinted cavities were investigated using adsorption assays, showing a homogenous population of binding sites and controlled microporosity.
  • The micropores in the imprinted polymer were found to be remarkable features for selectively capturing PAHs from aqueous solutions.
  • The research was supported by the Council of Scientific & Industrial Research (CSIR) - India and the University Grants Commission, India.
  • Reddithota J. Krupadam, a researcher at CSIR - National Environmental Engineering Research Institute, was involved in the study.

Statistics:

  • The researchers used AFM to investigate the geometric features of the imprinted cavities in three-dimensional detail at the sub-micron level.
  • The binding properties of the imprinted cavities were investigated using adsorption assays, which showed a homogenous population of binding sites and controlled microporosity.
  • The micropores in the imprinted polymer were found to be remarkable features for selectively capturing PAHs from aqueous solutions, with a reported capture rate of 99%.
  • 99% of PAHs were captured from aqueous solutions using the imprinted polymers.
