Stealth Nanoparticles with a “Self-Consuming” Shell for Long-Term Blood Vessel Imaging

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 16, 2025

The development of lanthanide-doped upconversion nanoparticle (UCNP)-based imaging with minimal autofluorescence and improved penetration depth is important in medical applications. Exogenous nanocarriers readily adsorb plasma proteins following intravenous administration (<0.5 min), resulting the formation a protein corona on fixed surface. facilitates UCNP interception by immune system, preventing targeted delivery to disease sites. In this study, we report novel surface-camouflaging strategy using lanthanide hydroxyl carbonate that slowly dissolved physiological phosphate serum. "self-consuming" inorganic-shell-modified UCNPs (denoted as UCSP-PEG) effectively reduce adhesion more than 90% through dissociation effect associated amphiphilic poly(ethylene glycol) (PEG)-modified determined an ex vivo assay. UCSP-PEG exhibits prolonged blood circulation time (t1/2 = 73.9 ± 9.5 185 times camouflage materials without "stealth" feature, can employ upconverted luminescence (UCL) monitor tumor-related vessels for at least 120 min. Based superior optical properties UCSP-PEG, application UCL dual-channel stereoscope magnification system has enabled observation capillaries high resolution, offering powerful tool monitoring biological activities fine tissue level. This work provides nanovehicle, resisting based significantly advance target-specific cancer diagnosis.

Biodegradable Persistent Luminescence Nanoparticles as Pyroptosis Inducer for High‐Efficiency Tumor Immunotherapy

Advanced Science, Journal Year: 2024, Volume and Issue: 11(39)

Published: Aug. 19, 2024

Abstract Pyroptosis possesses potent antitumor immune activity, making pyroptosis inducer development a promising direction for tumor immunotherapy. Persistent luminescence nanoparticles (PLNPs) are highly sensitive optical probes extensively employed in diagnosis and therapy. However, based on PLNPs has not been reported yet. Herein, polyethylene glycol–poly lactic acid‐co‐glycolic acid (PEG–PLGA: PP) modified biodegradable CaS:Eu 2+ (CSE@PP) synthesized as immunotherapy the first time. The CSE@PP biowindow persistent (PersL) pH‐responsive degradation properties, allowing it to remain stable under neutral pH but degrade when exposed weak (pH < 6.5). During within tumor, constantly releases H 2 S Ca while its PersL gradually fades away. Thus, signal can self‐monitor release. Furthermore, released result mitochondrial dysfunction inactivation of reactive oxygen species scavenging enzymes, synergistic facilitating intracellular oxidative stress, which induces caspase‐1/GSDM‐D dependent subsequent responses. In word, is confirmed that release pyroptosis‐mediated Immunotherapy. This work will facilitate biomedical applications inspire pyroptosis‐induced

Functionalized recycled polyethylene terephthalate plastic by rare earth oxide for electronic device and housing infrastructure applications

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 24, 2025

Abstract Recycled polyethylene terephthalate (RPET) was doped with Neodymium Oxide (Nd 2 O 3 : 0, 1, 2, 4, and 8 wt.%) to investigate its structural, optical, dielectric, mechanical properties. X-ray diffraction (XRD) analysis revealed that pure RPET exhibited an amorphous structure, while the incorporation ofNd induced formation of crystalline phases, crystallinity increasing as Nd concentration increased. Fourier-transform infrared (FTIR) spectroscopy identified chemical interactions between , evidenced by a new band around 535 cm −1 . Optical using diffuse reflectance UV–Vis showed reduction in gap from 3.75 eV for 2.25 8wt.% samples, indicating enhanced optical Dielectric studies doping significantly decreased dielectric constant RPET, contributing thermal stability constant. Furthermore, loss conductivity improved, observed across varying temperatures. Dynamic (DMA) adding wt.% reduced storage modulus 1.62 GPa approximately 0.26 at 35 °C, attributed structural softening. These improvements suggest -doped is suitable applications requiring conductive REPT, low modulus, stability, energy dissipation capabilities.
