Amplified Spontaneous Emission of DCM Dye in PMMA Polymer Using Copper Metal Disks Mold

Iraqi Journal of Physics, 2010
The effect of irradiation and exposure time of laser light on the fluorescence emission of DCM dye in PMMA polymer contained in the composition mold using different metals have been investigated. It was found that the fluorescence intensity decreases as

Protease‐Activated Theranostic Nanomedicine for Endometriosis Treatment

Advanced Functional Materials, EarlyView.
Endometriosis is a chronic gynecological disorder that affects a substantial proportion of reproductive‐aged women. In this study, we identify aberrant overexpression of matrix metalloproteinase‐9 (MMP‐9) in endometriotic lesions and develop a novel multifunctional nanomedicine that integrates MMP‐9‐targeted therapy, ratiometric photoacoustic (PA ...

Engineering Antigen Density on M13 Bacteriophage for Personalized Nanovaccine

Advanced Healthcare Materials, EarlyView.
Increasing antigen density on the phage capsid impacts phage uptake and antigen cross‐presentation by antigen‐presenting cells, leading to enhanced activation of antitumor CD8+ T cells in the draining lymph nodes. These activated CD8+ T cells subsequently recognize the antigen‐expressing tumors and mediate their specific cytotoxic killing, thereby ...

Macrophage–Fibroblast Crosstalk Governs Tumor Mechanics, as Revealed by Spatiotemporal Force Mapping in 3D Spheroids

Advanced Healthcare Materials, EarlyView.
This study shows crosstalk among tumor cells, fibroblasts, and macrophages alters the physical forces inside 3D tumor spheroids. Incorporating deformable microparticles in 3D tumor spheroids, the researchers mapped mechanical stresses spatially and with respect to tumor growth (temporally).
