Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

Advanced Science, EarlyView.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

SCANNING PHOTOACOUSTIC MICROSCOPY

Acta Physica Sinica, 1982
The principle, possible applications and prospects of the scanning photoacoustie microscopy are described briefly. The microscopy system presented herewith attains a resolution of about 4,5 μm. Some images of such samples as the interdigital transducer of surface acoustic wave, integrated circuit and in particular the subsurface structure of the ...

Vascular bifurcation mapping with photoacoustic microscopy

Biomedical Optics Express, 2020
The early detection of microvascular changes in cancer diagnosis is needed in the clinic. A change in the vascular bifurcation density is a biomarker for the sprouting activity. Here, Optical-Resolution PhotoAcoustic Microscopy is used for quantitative vascular bifurcation mapping in 2D after the creation of Virtual Tubes out of Bifurcations. In stacks

Single-shot photoacoustic microscopy of hemoglobin concentration, oxygen saturation, and blood flow in sub-microseconds

Photoacoustics, 2020
We present fast functional optical-resolution photoacoustic microscopy (OR-PAM) that can simultaneously image hemoglobin concentration, blood flow speed, and oxygen saturation with three-pulse excitation. To instantaneously determine the blood flow speed,
