University of Missouri researchers, led by Associate Professor Gary Baker, have engineered fluorescent polyionic nanoclays. These novel nanomaterials can be customized for applications in energy, environmental protection, and medical diagnostics.
The nanoclays, layered silicate materials, are functionalized with fluorescent molecules. This creates a tunable sensory platform, allowing precise control over optical signals.
These fluorescently tagged materials exhibit brightness levels reaching 7,000 units, rivaling the highest emission intensities reported. Their polyionic nature allows conjugation with biomolecules, enabling targeted drug delivery and biosensing.
Early tests suggest the nanoclays are biocompatible, paving the way for use as contrast agents in medical imaging. They also show promise in solar energy capture and environmental monitoring.
The team's findings, detailed in Chemistry of Materials, highlight the nanoclays' superior brightness, stability, and tunability. Researchers aim to expand the nanoclays' capabilities for precision medicine.
