  • UNY Faculty of Mathematics and Natural Sciences Students Utilize Banana Peel Extract to Develop Heavy Metal Detection Sensor
    Post date: 09/10/2025 - 08:42

    UNY Faculty of Mathematics and Natural Sciences students, members of the Student Creativity Program – Exact Research (PKM-RE) Team, have developed an environmentally friendly sensor to detect the heavy metal lead (Pb²⁺) in water. This sensor is based on Cu₂O/TiO₂ Nanotube Arrays (Cu₂O/TNA), synthesized through electrodeposition using a green synthesis approach.

    Uniquely, the team utilized banana peel waste extract as a source of natural polyphenols to aid the formation of Cu₂O particles. Polyphenols act as reducing agents, shape regulators, and stabilizers for the nanoparticles,...
