Application of Platinum Nanoparticle in Graphene Electrodes

Using platinum nanoparticle, graphene electrode impedance could be lower by 100times and transparent. The lower impedance graphene electrodes were able to record an image neuronal activity, such as Calcium ion spikes, at both macro cell and single cell levels. Graphene electrodes enable higher quality imaging of brain cell activity. Recently graphene electrode is a step closer to being adapted into next-generation brain imaging technologies and various basic neuroscience and medical applications.



Researchers have been exploring graphene electrodes for use in neural implants. They have several advantages over the traditional metal electrodes. They are flexible So they can confirm better to brain tissue. Also, they are transparent, which makes them possible to both record and see the activities of neurons directly beneath the electrodes that would otherwise be blocked by opaque metal materials.

Graphene electrodes are under high impedance, This hampers communication between the brain and the recording devices. The noisy reading comes as a result. The transparency of metal will be ruined if researchers try various techniques to reduce the impedance of the graphene, researchers have developed a technique to engineer graphene electrodes those are both 100times lower in impedance and transparent.

Gold Coated Nanorobots for detoxification of Toxic fluids from Blood

Researchers are making Nanorobots by giving Gold nanowires coat with a hybrid of platelets and red blood cell membranes. The hybrid cell membrane coating allows the nanorobots to perform different tasks of two different cells at a time. platelets, which bind pathogens like MRSA bacteria and red blood cells, which absorb and neutralize the toxin produced by these bacteria. Due to the gold coating nanorobots respond to ultrasound so that it can rapidly swim without chemical fuel. Due to this movement, the nanorobot efficiently mixes with the bacteria and toxins in the blood and speed up detoxification.

We can impart new capabilities on tiny robots such as removal of pathogens and toxins from the body and from the other matrices, by integrating natural cell coatings onto synthetic Nanomachines. If we will combine platelets and blood cell membranes into each nanorobot coatings then platelet targets bacteria, while red blood cells target and neutralize the toxins of those bacteria produced

High-frequency sound waves are effective to fuse the membrane together. With the separation of entire membranes from platelets and red blood cells, the hybrid coating is created. To make the nanorobots, researchers coated the hybrid membranes onto gold nanowires using specific surface chemistry.

The Nanorobots can travel up to 35micro meters per second in blood when powered by ultrasound.they are about 25times smaller than the width of human hair. In tests, researches used the nanorobots to treat blood samples contaminated with MRSA and their Toxins. As a result, these blood samples had three times fewer bacteria and toxins than affected samples. To make it economical, the scientists are working on making nanorobots out of biodegradable materials instead of gold.

The data at light speed moves by Nanowire

Recently Researchers of Nanotechnology have discovered a new way of production of Nanoscale wire that can serve as tiny, adjustable lasers. These tiny lessers have some excellent performance which is quite promising for the field of Optoelectronics(It is all about combining electronics and light to transmit data among other application). Lasers in a Nanoscale decrement could further bring light-speed data transmission to desktop and transform Computing. A standard technique can require expensive equipment and exotic condition to produce Nanowire.




Caesium, Lead and Bromide(CsPbBr3) are the three components of Nanowire that emits bright laser light after hitting by a pulse from another laser source. The Nanowire laser is very stable, emitting laser light for over an hour. It also was demonstrated to be broadly controllable across green and blue wavelengths. To interface photonic(light-based) with electronic devices, the nanosized wires are being developed.
