In the 1966 American science fiction film “Fantastic Voyage,” several American doctors shrink a submarine to a size smaller than a red blood cell and send it through blood vessels into the brain to clear a clot blocking the brain, ultimately saving a scientist’s life. From this film, we can see that the concept of … Read more
In today’s rapidly advancing technology, robotics has gradually permeated every aspect of our lives, especially in the medical field, where the application of robotic technology is becoming increasingly widespread and important. Traditional medical robots, such as surgical robots, have demonstrated exceptional performance in minimally invasive surgeries and precise excisions. However, with continuous technological advancements and … Read more
The cancer-associated fibroblast (CAF) barrier in pancreatic ductal adenocarcinoma (PDAC) significantly restricts clinical prognosis. The main obstacles in PDAC treatment include limited immune cell and drug penetration, as well as an immunosuppressive microenvironment. Based on this, Yongjun Liu and Na Zhang from Shandong University reported a “shooting fish in a barrel” strategy by preparing a … Read more
iNature Self-assembling hydrogels for mechanical support and drug delivery have been widely studied in the context of traumatic brain injury (TBI). However, most self-assembling hydrogels rely on polymer carriers or the introduction of exogenous inactive substances, often raising biosafety concerns and making clinical translation difficult. On October 9, 2024, a research paper titled “Small Molecule … Read more

Recently, Professor Koen Raemdonck’s team at the University of Ghent, Belgium published a research paper titled “A lipid nanoparticle platform for mRNA delivery through repurposing of cationic amphiphilic drugs” in The Journal of Controlled Release, Volume 350, 2022. The team utilized various cationic amphiphilic drugs as structural and functional components to prepare lipid nanoparticles (LNPs) … Read more
Abstract Background:A nebulizer is a medical device that delivers aerosolized medication directly to the lungs to treat various respiratory diseases. However, breathing patterns, respiratory rates, airway diameters, and the amount of medication delivered by the nebulizer may be related to respiratory diseases. Methods:In this study, we developed a breathing simulator consisting of an airway model, … Read more
Have you heard of “head transplant surgery”? I saw this news a while ago, but when I searched online, the world’s first head transplant surgery was actually performed back in 2016… Modern medicine always gives us the illusion – Afraid of the pain of injections? Doctors can use needle-free injectors to give you shots; Need … Read more
In a new study, researchers from the Max Planck Institute for Intelligent Systems in Germany combined robotics with biology, equipping Escherichia coli with artificial components to construct biohybrid microrobots. First, they attached several nanoliposomes to each E. coli, which encapsulated indocyanine green (ICG) that melts when exposed to near-infrared light. Moving inward, these nanoliposomes contain … Read more
