Hybrid Cell Membrane‐Coated NIR‐Photodegradable Carbon Nitride Nanozymes for Mangiferin Dual‐Targeted Delivery and Gas Mild Photothermal Immunotherapy Against Liver Fibrosis via the HIF‐1α/HSP27 Axis

Carbon Neutralization, Volume 5, Issue 4, July 2026.
We developed HMCCNs@MAN, a biomimetic drug–gas codelivery platform for precise mild photothermal immunotherapy of liver fibrosis. Coated with hybrid macrophage‐aHSC membranes, it enables dual‐targeted delivery of MAN to the hepatic fibrosis site. Under NIR laser irradiation, HMCCNs@MAN can generate oxygen, release MAN, and produce heat.

Enhanced Visualization of Erythrocytes Through Photoluminescence Using NaYbF₄:Yb³⁺,Er³⁺ Nanoparticles

Biosensors
Rare-earth nanoparticles (RE-NPs), particularly NaYF4:Yb3+,Er3+, have emerged as a promising class of photoluminescent probes for bioimaging and sensing applications. These nanomaterials are characterized by their ability to absorb low-energy photons and

Laser Transfer of Upconversion Nanoparticles

JETP Letters
A method of the transfer of NaYF4:Yb3+Tm3+/NaYF4 upconversion core/shell nanoparticles with an average size of 30 nm via laser-induced forward transfer is proposed. The method provides a high spatial resolution by creating a “sandwich” structure on the donor substrate: for reliable fixation, nanoparticles are located between gold layers 50 and 20 nm ...

Nanotoxicological Assessments of Upconversion Nanoparticles

Upconversion nanoparticles (UCNPs) are highly efficient luminescent nanomaterials with emission in the visible spectra while being excited by near-infrared region light (NIR). With their unique properties such as high luminescence intensity, sharp emission peaks with narrow bandwidth, large anti-Stokes’ shift, and sizes smaller than 100 nm, UCNPs have ...
