The Use of Low-Cost Immobilized DNA Aptamers on a Cellulose Filter to Remove Antibiotic Residues from Effluents

The project will develop a cellulose filter containing immobilized DNA aptamers, molecules that bind to a specific target molecule, that act as specific and high affinity probes for the uptake and retention of antibiotic molecules present in effluents. Nowadays, the removal of antibiotic residues from effluents is mainly based on chemical processes and physical methods that require expensive technologies and costly maintenance. The success of this project will represent a wastewater treatment option that is low-cost and environment-friendly.
