Recent advancements have focused on developing nanoscale persistent room-temperature phosphorescence (pRTP) structures to expand their applicability in biomedical fields. Traditional fabrication methods typically produce surface-coated core-shell pRTP nanoparticles composed of nonbiocompatible emitters at very high concentrations the core. To overcome this limitation, polymeric nanosystems been presented study as a promising alternative by embedding RTP molecules within biocompatible polymer matrix, thereby significantly reducing required concentration molecules. These were fabricated using poly(lactic acid) (PLA) matrix an effective microemulsion-based method. They exhibited similar properties traditional nanoparticles, showing comparable long-lasting with lifetime 118 ms even when phosphorescent molecule content is below 2%. Moreover, excellent biocompatibility and stability demonstrate interesting reversible photoactivated properties. successfully applied for vivo imaging signal-to-noise ratio (SBR) 2061, maintaining strong long-lived emissions 20 min. results highlight viable approach advancing technology biological applications.

Tumor Treatment by Nano-Photodynamic Agents Embedded in Immune Cell Membrane-Derived Vesicles

Pharmaceutics, Journal Year: 2025, Volume and Issue: 17(4), P. 481 - 481

Published: April 7, 2025

Non-invasive phototherapy includes modalities such as photodynamic therapy (PDT) and photothermal (PTT). When combined with tumor immunotherapy, these therapeutic approaches have demonstrated significant efficacy in treating advanced malignancies, thus attracting considerable attention from the scientific community. However, progress of therapies is hindered by inherent limitations potential adverse effects. Recent findings indicate that certain strategies, including phototherapy, can induce immunogenic cell death (ICD), thereby opening new avenues for integration immunotherapy. Currently, development biofilm nanomaterial-encapsulated drug delivery systems has reached a mature stage. Immune membrane-encapsulated nano-photosensitizers hold great promise, they enhance immune microenvironment. Based on bioengineering technology, membranes be designed according to microenvironment, enhancing targeting properties nano-photosensitizers.
