Bistable rotaxanes might be pressed into service as valves so that nanoparticles only release drugs in desired target areas.
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.
