This research developed an environmentally friendly way to produce quantum dots (tiny light-emitting particles) using plant roots instead of harmful chemical methods. The quantum dots produced were stable and showed promising properties for use in biological imaging and medical applications. Impacts on everyday life: • Provides a safer, greener method for producing materials used in medical imaging • Reduces environmental pollution from chemical manufacturing processes • Advances development of better biological imaging tools for medical diagnosis • Shows potential for improving detection methods in medical testing • Demonstrates how plants can be used to create advanced technological materials
