A (South) African perspective on nanomedicine development

South-AfricaNanotechnology has the ability to completely transform the health care sector, particularly in developing countries like South Africa, where access to effective healthcare is still a challenge for millions of people living in poverty-stricken environments. Many African countries, despite having policies and strategies in place, struggle to allocate sufficient resources for research in nanomedicine. Most of the research conducted on the subject in Africa is focused on academic interests, rather than practical applications.

Incongruent results from proteomics core facilities compromise nanoparticle protein corona research

heatmapIts significance of the protein corona for biomedical applications lies in its role of imparting a unique biological identity to the nanoparticle, which could be very different from the pristine nanoparticle surface. Robust characterization of the identity and abundance of the protein corona is entirely dependent on liquid chromatography coupled to mass spectroscopy. Unfortunately, the variability of this technique for the purpose of protein corona characterization remains poorly understood.

Identifying favorable immunological profiles suitable for personalized treatments with RNA nanoparticles

nucleic-acid-nanoparticleTherapeutic nucleic acids (TNAs) and nucleic acid nanoparticles (NANPs) are designed to enact specific intracellular responses beneficial for various biomedical applications. TNAs become especially attractive to researchers and clinicians since their functional versatility, programmability and modularity show great promise for treating disorders such as viral infections, cancers, and genetic disorders. Scientists explore how the immune responses to NANPs change with various factors such as dimensionality (3D vs. 2D), composition (DNA vs. RNA), and functionalization with TNAs.

Nanobiomimetic strategies for medicine

tumor-cellThe defenses of the body's immune system tend to destroy synthetic nanoparticles and frequently they are captured and removed from the body within few minutes. This, of course, is a major barrier to the use of nanotechnology in medicine. In order to evade the host immune response, researchers are demonstrating that the combination of nanomaterials and biomimetic strategies can change diverse nanomaterials from 'distinguishable state' to 'camouflage state' and thereby improving technologies for nanomedicine applications.

Novel platform allows five types of programmable optothermal manipulation of micro- and nanoparticles

round-particleResearchers have developed an optothermal platform with five manipulation modes - printing, tweezing, rotating, rolling, and shooting - using a single Gaussian laser beam. Switching between the different modes is achieved by simply tuning the optical power or the distance between laser and object, and can be automated through software programming. This novel multimodal manipulation technique relies on the coordination of multiple thermal forces instead of light-matter interactions, i.e., the mechanism of traditional optical tweezers.
