Vaccines combat diseases and protect populations from outbreaks, but the life-saving technology leaves room for improvement. Vaccines usually are made en masse in centralized locations far removed from where they will be used. They are expensive to ship and keep refrigerated and they tend to have short shelf lives.

A team of material scientists, chemical engineers and physicists from the University of Pennsylvania has made another advance in their effort to use liquid crystals as a medium for assembling structures. In their earlier studies, the team produced patterns of “defects,” useful disruptions in the repeating patterns found in liquid crystals, in nanoscale grids and rings. The new study adds a more complex pattern out of an even simpler template: a three-dimensional array in the shape of a flower.

Study suggests as an efficient semiconducting material that the prepared material can be utilized in solar cells, optoelectronic, power, semiconductor devices, catalysis, electronics, photonics, sensing, medicine, lithium-ion batteries, filters, anti-reflective & high reflective coatings, water splitting devices and to solve many serious environmental / pollution challenges. It is widely used as a photo-catalyst due to its relatively cheap cost, non toxicity and high chemical stability. It has more applications in various industries like aerospace, sports, paint (to give high gloss, rich depth of color and to replace metal lead), food (to increase the shelf life of products) and cosmetics (UV protection in sunscreens and many other products).

A new nanotechnology-based technique for regulating blood sugar in diabetics may give patients the ability to release insulin painlessly using a small ultrasound device, allowing them to go days between injections – rather than using needles to give themselves multiple insulin injections each day. The technique was developed by researchers at North Carolina State University and the University of North Carolina at Chapel Hill.

Researchers from Karolinska Institutet have shown that nanoparticles made from biodegradable plastics can overcome drug resistance in breast cancer cells. Such resistance is especially common in relapsing cancer patients and depresses, even neutralises the effect of the therapy against the tumour in many instances.

Recent advances in graphene research provide various possibilities to enhance performance characteristics and current approaches to design new bio-devices. Especially, smart and flexible bioelectronics on graphene has emerged as a new frontier in this area. Graphene has started to be seen an ideal signal transducer and promising alternative for the production of low cost bioelectronics devices. However, control and regulation on biological systems are always desired for advance applications and productions. The integration of biomolecules with electronic elements to fabricate functional devices attracts considerable attention because of the basic fundamental scientific questions and the potential applications of the system.
