An Iranian company has developed a heart attack diagnosis device prototype. The final device, which uses graphene for signal boosting and sensitivity, will be small and portable. It is expected to reach mass production by next year.
Over the past decade, high-security printing inks have been developed using various technologies. A group of researchers from Iran, USA, and Japan have been working on developing a new kind of secure inks.
By using the surface tension-directed self-assembly of a cellulose nanocrystal, the research team could produce a cheap and efficient high-security ink which can be used in printing birefringent figures. As well as low cost and high efficiency, the tests show that the novel ink is non-toxic which makes it unique among other competing products.
The results of the study are published in the Journal of ACS applied materials & interfaces with an impact factor of 8.
