Published: Jan. 1, 2024

Silicon nanocrystals (SiNCs) have attracted considerable attention in many advanced applications due to silicon's high natural abundance, low toxicity, and impressive optical properties. However, little has been paid fluorescence anti-counterfeiting based on lipophilic silicon nanocrystals. Moreover, it is also a challenge fabricate aging-resistant coatings Herein, this paper presents demonstration of fluorescent red In work, (De-SiNCs) with were prepared first by thermal hydrosilylation between hydrogen-terminated (H-SiNCs) 1-decene. Subsequently, new SiNCs/PDMS coating (De-SiNCs/DV) was fabricated dispersing De-SiNCs into reinforcing PDMS composites vinyl-capped silicone resin. Interestingly, the De-SiNCs/DV exhibit superior transparency (up 85%) visible light range, outstanding stabilities an average lifetime 20.59 μs under various conditions including acidic/alkaline environments, different organic solvents, high-humidity environments UV irradiation. Meanwhile, encapsulation beneficial enhancing mechanical properties stability composites. Additionally, exhibits excellent effect cotton fabrics when used as ink screen-printing. These findings pave way for developing innovative flexible multifunctional future.

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.

Optothermal‐Stimulated Persistent Luminescence Imaging and Therapy (OSPLIT)

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

Published: March 31, 2025

Abstract Persistent luminescent nanomaterials have significantly advanced in vivo bioimaging and biosensing by emitting photons after excitation ceases, effectively minimizing tissue autofluorescence. However, their application biomedical fields such as tumor theranostics is limited low brightness rapid signal decay. To address these issues, OSPLIT (optothermal‐stimulated persistent luminescence imaging therapy), a dual‐function strategy for treatment introduced. The approach enhances the release of charge carriers from deep traps lanthanide‐doped nanoparticles, resulting 73 fold increase within second near‐infrared (NIR‐II) window. In living mice, it enables high‐contrast lymph node metastases, with signal‐to‐background ratio 11.8 times greater than conventional NIR‐II fluorescence. Optothermal‐boosted nanoparticles are effective ablating metastasis preventing spread. These findings highlight potential optothermal stimulation to enhance both therapeutic applications.
