Multifunctional nanoplatform for efficient cancer photo-immunotherapy

May 30, 2022 (Nanowerk News) Cancer immunotherapy is a treatment modality against tumor growth and metastasis by stimulating host immune responses. Phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), is a less invasive treatment compared with chemotherapy. To be specific, PDT and PTT-induced immunogenic cell death can release tumor-associated...

Lever-inspired triboelectric nanogenerator with ultra-high output for pulse monitoring

May 30, 2022 (Nanowerk News) Triboelectric nanogenerators (TENGs) can collect mechanical energy extensively through contact initiation and electrostatic induction. TENGs have shown a wide range of applications in self-powered sensors and mechanical energy harvesting. The contact-separation mode is one of the most fundamental and common modes of working. Previous studies...

Ultrasound-guided microbubbles boost immunotherapy efficacy

May 30, 2022 (Nanowerk News) Researchers at The University of Texas MD Anderson Cancer Center have developed an ultrasound-guided cancer immunotherapy platform that generates systemic antitumor immunity and improves the therapeutic efficacy of immune checkpoint blockade. The findings from the preclinical study were published today in Nature Nanotechnology ("Cancer immunotherapy...

Turning high-rise buildings into batteries

May 30, 2022 (Nanowerk News) The world’s capacity to generate electricity from solar panels, wind turbines, and other renewable technologies has been steadily increasing over the last few years, and global renewable electricity capacity is expected to rise still further by more than 60% from 2020 levels by 2026. This...

Multi-functional bandage helps wounds to heal

May 30, 2022 (Nanowerk News) Researchers at the Technical University of Munich (TUM) have developed a film that not only protects wounds similar to the way a bandage does, but also helps wounds to heal faster, repels bacteria, dampens inflammation, releases active pharmaceutical ingredients in a targeted manner and ultimately...

A step closer to next-generation semiconductors

May 30, 2022 (Nanowerk News) To realize artificial intelligence systems and autonomous driving systems, which is often seen in movies, in everyday life, processors that function as the brain of computers must be able to process more data. However, silicon-based logic devices, which are essential components of computer processors, have...
