NANOMEDCINES

There are different types of Nanomedicines varying from pills, nanomedicines use with surgical machines and even nanotechnologies that were once only imagined in stories. The four dominant nanomedicines that current scientists are still working on are: Gold Nanoshells, Nanosponges, Cornell Dots and Nanorobots. 

Gold Nanoshells

NM1.1, NM1.2

Nanosponges

NM1.3, NM1.4

  • Invented by Naomi Halas and Jennifer West. 
  • Gold Nanoshells are tiny spheres of glass covered with Gold
  • Naomi Halas and Jennifer West decided to modify these gold nanoshells to capture near-infrared wavelengths or colors of light. 
  • They could use these shells and technologies in cancer therapy and prevent side-effects.
  • The Nanoshells could capture heat from the infrared wavelengths and burn the tumor away without causing side-effects or damages to tissues nearby. 
​
  • Soak up harmful toxins found in some venoms and bacteria (NM1)
  • Bacterias and toxins such as E. Coli target red blood cells and poke holes in them, more toxins are spread into the bloodstream, causing more cell death 
  • Nanosponges are coated with a layer of red blood cell and toxins attacked nanospones as it attacked the red blood cells
  • The core of the nanosponges is made of latic acid, an organic material found in the body and traps the toxins. (NM2)

Cornell Dots 

Nanorobots

NM1.5, NM1.6

NM1.7, NM1.8

  • Cornell dots, are nanoparticles containing several dye molecules, surrounded by a protective silica shell, making the entire particle about 25 nm in diameter. (NM3)
  • Nanoparticles deisned to adhere to and lighten up a cancer cells (NM4)
  • The core containing organic dyes are encapsulated in a of pure silica. (NM5)
  • Cornell Dots were originally designed to "explore" flourescent. Now, it can be used to sense the environment and further more expand for other functions such as drug delivery.
  • Wienser, the founder of C Dots, now illustrated a porous dot called the mC-Dots, it could finder the tumor, kill it and escape the body through urine in a few hours. (NM6) 
  • Nanorobots are machines that could replicate themselves at an atomic level.
  • The terms nanobot, nanoid, nanite, nanomachine, or nanomite are also used and referred to as nanorobots.
  • The potential use of Nanorobots in medical fields are the increase of accuracy in diagnose, target, locate and deliver drugs to tumor sites in the body.
  • Another application of Nanorobots are increasing the recovery rate of injuries. Nanorobots can attach themselves onto white blood cells and squeeze their way to the injury sites. If chemicals are delivered to the injury site, it might accelerate the recovery.
