Room temperature cyclable healing of inorganic perovskite films

nanoparticlesAlthough developed only recently, inorganic halide perovskite quantum dot systems have exhibited comparable and even better performances than traditional quantum dots in many fields. They are expected to be applied in display and lighting technologies. Researchers now have reported an interesting cyclable surface dissolution and recrystallization phenomenon of inorganic perovskite crystals. This allows them to freely change size between nanometer and micrometer scales, and can be used to healing the defects inside perovskite films and hence improve the performances of optoelectronic devices.

Nanotechnology-based approach to repair the cancer cell suicide mechanism

nanoparticles_in_mitochondriaStudies show hat mitochondrial metabolism theoretically is a plausible target for cancer therapy. Mitochondria are the primary controllers of cellular suicide; however, cancer cells trick this normal cellular mechanism and evade this process leading to uncontrolled cellular growth. To trigger the suicide switch back on, new work uses a highly selective nanotechnology-based approach to deliver a widely available small molecule commonly found as a by-product of a water chlorination process.

A guide to the nanotechnology used in the average home

houseThere is an often-asked question: 'When are we finally going to start seeing nanotechnology products on the market?' As a matter of fact, the average home is already filled with products enhanced or reliant upon nanotechnology. In fact, there are several online repositories listing the more than 2,000 commercially available products that incorporate nanotechnology. The application of nanotechnology in some areas, such as batteries, microelectronics and sunscreens is relatively well known. Let?s take a virtual tour through a home to see what else we can find.

Graphene coated microbubbles as superior photoacoustic imaging contrast agent

graphene_microbubbleResearchers have demonstrated that the coupling of pristine graphene sheets on practically any polymer surface can be accomplished in mild reaction conditions and in aqueous medium. The method leaves intact the 2D planar structure of graphene preserving its original features. This novel hybrid construct enables in vivo photoacoustic signal enhancement and is a very promising step forward for an implementation of photoacoustic imaging, a powerful preclinical diagnostic tool.

Overcoming adaptive resistance in cancer with a 2-in-1 nanoparticle approach

nanodrugCurrently in the clinic and in clinical development, there is heavy emphasis placed on understanding how drugs can be 'complementary'. That is to say, what combination of drugs will be most effective in killing tumor cells and overcome potential resistance mechanisms. In fact, adding synergistic combinations of drugs is reshaping how cancer is treated, even in the context of immunotherapy. A new study provides critical evidence that complementary drugs must be in spatial proximity to truly exert their synergistic potential.

Nanotechnology education for the leaders of tomorrow

nanotechEducation has long been recognized as an important factor for growing the fields of nanoscience and nanotechnology and solidifying and expanding their roles in the global economy. Leading researchers from the field discuss innovative learning models that are being applied at the undergraduate level in order to train future leaders at the interface of engineering and management. They have a set of five recommendations to improve the current situation.

Topically applied curcumin nanoparticles alleviates joint pain and slows progression of Osteoarthritis

OsteoarthritisResearchers have shown, using a mouse model of osteoarthritis, that curcumin loaded nanoparticles topically applied to arthritic knees stopped the progression of the disease and eliminated associated pain by locally delivering curcumin to the fat pad associated with the knee cap. The study also demonstrated several osteoarthritis relevant inflammatory pathways were suppressed by curcumin, including those that result in the production of proteins that destroy cartilage.

Nanotechnology's hot pick-up artist

grapheneFirst there was graphene, an atomically thin film of carbon atoms with record-crushing properties. Then thousands of other atomically thin materials entered the scene which can be layered to create new hybrid supermaterials - so called van der Waals heterostructures. Until now, only a few leading groups have been able assemble these materials with sufficiently high quality. With the 'hot pickup' stacking method, researchers aim to make atomic scale nano-assembly faster and easier than ever before.
