NANOTUBES !

NANO ROBOTDetects the infected area.Provides a dose of medication directly to the infected area.Clears the built up cholesterol from our arteries and saves us from heart attack.To cure cancer by eradicating malignant cells.

NANO SHELLSIn FLESH WELDING which can replace the old clumsy and infection prone stitching method after the surgery.A liquid containing GOLD COATED NANOSHELLS was dribbled along the seam and an infrared laser was traced.

CLUSTERS OF SILVER NANOPARTICLESShaped into a sort of nanomirror and placed under a specimen in a microscope.To study both the outer and inner structure of a specimen.

NANO ELECTRONIC Computer will interpret, control, detect and respond to the signals of the body when there is feel of sensation.Decay of nervous system can be detected and cured.

DEMANDS

NANONEPHROLOGY For the diagnosis, therapy and management of diseases of the kidney.To study the cellular processes in kidney cells.

ORTHOPEDIC IMPLANTSHost bone and vascular cells are regenerated.Generally titanium is used.But the usage of NANO-HA CRYSTALS in implantation of bones cures quickly.

STEM CELL BIOLOGYMagnetic nanoparticles are used to isolate and group stem cells.Nano tubes are used for delivery of gene or drugs into stem cells.

DENDRIMERSize less than 10nm.Used in long circulatory, controlled delivery of drugs to the infected area and liver targeted delivery.

NANO IN BLOODArtificial mechanical red blood cell.Able to deliver 236 times more O2.

NANO IN EYEA novel nanoscale dispersed eye ointment for the treatment of severe evaporation dry eye.Nano scopic robots for eye surgery is the below picture

OTHER USES Nano wires are useful for disease protein biomarkers detection, DNA mutuation and detection.Nano pharmaceutical can be used to detect diseases at earlier and makes the drug discovery stages earlier.

CONCLUSIONHence nanomaterials have increased surface area and nano scale effects hence used as a tool for the advancement of drug and gene delivery, biomedical imaging and diagnostic biosensors. NANO MATERIALS require less energy to produce than CONVENTIONAL MATERIALS.
