Published: Nov. 3, 2024

Glass, a diverse family of amorphous materials, has significantly advanced human society across various fields. The demand for flexible ultrathin glass, driven by modern optical displays and portable optoelectronics, presents challenges in energy consumption, fabrication complexity, recycling. Here, we demonstrate flexibility full-color luminescence large-scale glasses derived from readily available natural resources, specifically egg albumen (EA) gelatin (GEL), via an evaporation-driven self-assembly process. dynamic crosslinked networks formed through hydrogen bonding between EA GEL impart both high hardness to the glasses, with flexural strength values comparable state-of-the-art inorganic organic glasses. Additionally, EA–GEL-based exhibit excitation-dependent time-gated chiral ultralong phosphorescence color blue red, lifetime up 180.4 ms. With their easy processability emission, these biogenic can be fabricated into anti-counterfeiting patterns information codes. There is increasing thin, but its recycling complex. authors report development glass luminescence, albumin gelatin.

Modulation of Near‐Infrared Afterglow Luminescence in Inorganic Nanomaterials for Biological Applications

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 10, 2025

Near-infrared afterglow luminescent inorganic nanomaterials (NIR-ALINs) possess the unique property of continuing to emit near-infrared (NIR) luminescence after excitation ceases. They demonstrate excellent photostability, deep tissue penetration, and high imaging signal-to-noise ratio (SNR). Additionally, NIR-ALINs can be re-excited in vivo using visible (Vis), NIR light or X-rays, which avoids need for continuous situ excitation, thus eliminating autofluorescence biological tissues reducing tediousness multiple injections. These features make particularly attractive applications. In recent years, a series with prolonged time enhanced intensity have been discovered. However, development still faces significant challenges, as their performance is usually insufficient satisfy practical There lack systematic analysis strategies regulation nanomaterials. This review highlights rational design modulation NIR-ALINs, focusing on host substrate selection, trap engineering surface modification. Moreover, applications bioimaging, bio-detection disease therapy are summarized. Finally, present challenges perspectives applications, such properties unclear biosafety, also discussed.
