As a follow-up to Monday’s post on optimizing nanoparticle design for nanotech drug delivery, the same research group has also demonstrated the advantages of a multistage approach in which micrometer-sized mesoporous particles are used to deliver two different nanoparticles in a way that circumvents some of the biological barriers that bedevil attempts to precisely deliver… Continue reading Nanotechnology uses two-stage vehicle to deliver drugs
Nanotech drug delivery vehicles may soon improve because it turns out that even those that appear to be promising are not well-designed.
In “Nanotech Puts Cancer In The Cross Hairs” at Forbes.com, Josh Wolfe describes the approaches of a number of companies developing nanotechnology-based treatments for cancer. Although only a snapshot of an area of intense activity, this overview highlights a number of the important issues. Unfortunately, when it comes to treating cancer, modern medicine is still… Continue reading Many companies trying to treat cancer using nanotechnology
A properly sized nanoparticle linked to a peptide that binds specifically to cartilage proved an effective drug delivery method when injected into the knees of mice.
Tetrahedrons made from DNA that extend and shorten in response to added short strands of DNA may provide new nanotech methods of drug delivery, but may present even more exciting possibilities for atomically precise functional nanosystems.
The Royal Society of Chemistry brings news of early work leading toward designed engines for nanomachines: Dutch scientists have made nanotubes move using enzyme-powered motors. Ben Feringa and co-workers from the University of Groningen, The Netherlands, have designed engines for nanomachines that could potentially be used in the body. Hydrogen peroxide has proven useful as… Continue reading Nanotechnology: Early work on nanomotors
In the postal mail today is the annual research report (PDF) of the CNSI, California NanoSystems Institute. Last month on Dec. 14 was the dedication ceremony (includes video) for their beautiful new nanotechnology building at UCLA. Thirteen projects were singled out for coverage in this year’s report. Our favorite is “Nano Machine Center for Targeted… Continue reading Nanomachines to fight cancer at California NanoSystems Institute
Those of you who subscribe to Foresight’s free Weekly News Digest (sign up using the Join Email List box at upper right of our home page) have seen that practically every week there’s new positive results to report on nanotechnology for drug delivery, especially for cancer. A summary of where to read about these advances… Continue reading Nanotechnology medicine: will it be affordable?
A post by Roland Piquepaille on ZDnet further exploring a topic recently covered here: nanoscale robotic devices for medical applications. The site allows you to indicate whether you want this subject covered in the future or not. Excerpt: The idea of using nanorobots to deliver drugs and fight diseases such as cancers is not new…But… Continue reading More on nanotechnology for medicine using nanorobots
Foresight members will recognize the names of researchers Robert Freitas and Tad Hogg. These two in the U.S. have now teamed with others from Australia to model nanotechnology robotics for medical applications, as described at PhysOrg.com. Excerpts: Virtual 3D nanorobots could lead to real cancer-fighting technology From eliminating the side effects of chemotherapy to treating… Continue reading Nanotechnology modeling for medical nanorobots
