A coordination driven ‘heat-set’ Zr-gel: efficient fluorophore probe for selective detection of Fe 3+ and nitrofuran-based antibiotics and smart approach for UV protection

and NFT), with consistent efficacy in quenching activity up to five consecutive cycles. More interestingly, colorimetric, portable handy paper strip, thin film-based smart detection approaches (under an ultraviolet (UV) source) were introduced to make this material a viable sensor probe in real-time applications. In addition, we developed a facile method to synthesize CPG-polymer composite material that can be utilized as a transparent thin film to protect against UV radiation (200-360 nm), with approximately 99% absorption efficacy.
