A new injectable material designed to deliver drug therapies and sensor technology to targeted areas within the human body is being developed by a biomedical engineer who says the system can lock its payload in place and control how it is released.
When capturing images at the atomic scale, even tiny movements of the sample can result in skewed or distorted images - and those movements are virtually impossible to prevent. Now microscopy researchers at North Carolina State University have developed a new technique that accounts for that movement and eliminates the distortion from the finished product.
In common perception, carbon dioxide is just a greenhouse gas, one of the major environmental problems of mankind. For Warsaw chemists CO2 became, however, something else: a key element of reactions allowing for creation of nanomaterials with unprecedented properties.
Resistance of tumor cells toward multiple cytostatic drugs is a serious problem in cancer treatment. Researchers have now introduced a new approach to gene therapy that could counter this problem: The gene that codes for resistance is 'silenced' through the use of an ingenious nanocomplex.
In the US, someone suffers a heart attack every 34 seconds -- their heart is starved of oxygen and suffers irreparable damage. Engineering new heart tissue in the laboratory that could eventually be implanted into patients could help, and scientists are reporting a promising approach tested with rat cells. They published their results on growing cardiac muscle using a scaffold containing carbon nanofibers
As part of his PhD, postdoctoral research fellow Dr Daniel Tune has designed a computer modelling system that shows which combination of carbon nanotubes absorb the most sunlight, therefore providing the most energy.
