Dr. Stepanek's prototype "chobots" are less than a hair's breadth across:
Frantisek Stepanek of Prague's Institute of Chemical Technology has announced that he is developing a new variety of nanobots. The holy grail of nanoscience has been to develop effective nanobots - robots that are small enough to travel inside the human body and make repairs. One of the great hurdles scientists have been facing in creating these potentially life-saving machines has been the difficulty of shrinking the gears and circuitry used in traditional robots down to a scale that can potentially flow through the bloodstream or even enter cells. Dr. Stepanek hopes to overcome this hurdle by avoiding it entirely: instead of trying to create a small version of a computer, he is creating artificial versions of simple life. Although his creations are not alive (they do not evolve or reproduce), Dr. Stepanek hopes that (eventually) they will be capable of tasks such as delivering medicine or detecting and destroying cancerous cells. Like living organisms, however, their programming (instructions) will be encoded as chemical patterns inside of their gelatinous cells. The individual efficacy of each "chobot" (as they are called) is limited, however, just like their biological counterparts (such as white blood cells), they will function en masse: by sending out molecular signals to each other, the chobots will be able to work as a team to solve problems from killing cancerous cells to cleaning water supplies.

1. Had strong facts
2. Used easier words to help the reader understand better
3. Explained the whole article
1. Could have broken up in paragraph form
2. Could have talked more about nanoscience
1. I learned that nanobots could crawl into a human's body to do repairs
1- cool facts
2 - interesting
3 - readable
1- could have provided more information on the application of these chem nanobots
2- could have dived deeper into the background of this field of study
1- I learned what chemical nanobots are
3 Things I liked
-This article was written about a superbly interesting topic that very easily sucked me in.
-It war written very clearly, with a clear understanding of the topic.
-Robots are awesome and I like to read about robots.
2 Things that could have been improved
-Though this article was superbly written there could have been a tad more emphasis on what these new life forms are made of.
-I would have also liked to have known what previous advancements have been made before this in this field.
1 Thing I learned
-It is outstanding how far technology has come in aiding the field of medicine. A few years ago this would not have been thought of at all possible. I was completely blown away to learn that advancements such as this in medical science. I am looking forward to hearing of further advancements on this topic.
