Nanoparticles Reprogram Tumor-Associated Macrophages Into Pro-Inflammatory M1 States in ssalimpour

Solid tumors are not merely collections of malignant cells but complex ecosystems comprising tumor cells, stromal cells, and the extracellular matrix (ECM). The tumor microenvironment (TME) fosters immunosuppression through tumor-associated macrophages (TAMs), myeloid-derived suppressor cells (MDSCs), regulatory T cells (Tregs), and cancer-associated fibroblasts (CAFs), while physical barriers such as dense ECM and abnormal vasculature hinder drug penetration. 10/10/2026

Photoelectrochemical water splitting offers a clean path to produce hydrogen fuel directly from sunlight and water. Quantum dots—nanoscale semiconductor crystals—are highly promising for this application due to their tunable bandgaps and strong light absorption. However, most high-performance quantum dots rely on toxic heavy metals such as cadmium or lead, limiting their practical deployment. 10/10/2026

Most of today's computer chips — also sometimes known as conventional integrated circuits — use electrons to deliver their signals via semiconductor materials and metallic components. In contrast, photonic integrated circuits use faster signal carriers, such as photons or quantized "light particles." 10/10/2026
