I really think that you did a great job with this page. There is a large emphasis on application throughout the wiki which has its strengths given the audience. I do think that there are a fe sentence structure issues and some material that would be nice to add. You are the expert in this  stuff so please take my advice, with respect to the content, with a grain of salt.

Introduction
I like the points that you address, as far as versatility and challenges in design. One thing that I think needs a little work is the sentence structure. I noticed that the opening sentence is a hard to read. There is a lot of good stuff in it, but I think that it could be broken up a little bit. I think that the first sentence can be broken up into three different sentences addressing the purpose and challenges in application and decomposition. As it reads it is just a little hard to follow. Also the term breakdown is used several times, and I was wondering if the term decomposition could be used interchangeably. Overall I think that the intro hits all the areas that it should, and the content is good. I do think that it need a little restructuring though.

History
I really found the history of these polymers to be interesting. I think your decision to make history a section was a good choice given the natural quality of a lot of these polymers. One thing that I did not like about the history section in the opening two sentences. I understand what you are trying to say, but I think there may be better ways to say that biodegradable polymers have a been around for a while. If you remove the two sentences I think it would be more fluid. I really like how you covered a large timespan. It is easy to get wrapped up in what is cutting edge, but I think you did a really good job covering as much time as possible and pointing out many things. Nice! 

Structure and properties
This section was really nice. I really like the scheme that you have in the beginning. One nit picky thing I want to point out, is that think that there is a repeat in the first sentence of ester and ester bonds. Also in the first sentence you mention that some of polymers, such as proteins, contain amide bonds.  I think a nice addition to the scheme next to biopolyesters would be biopolyamides and a following box labelled peptides. I notices that you mention it in the next section and it may be a good place to show it in your scheme. I really like the properties section of your article, you address a lot of challenges with respect to degradation.  Another nit picky thing, I think the term impractical  in the third sentence could be changed to something more science like. 

Synthesis
This is section is great. I printed the article off to read it and as I was reading I thought ""They should really include a scheme for polyurethanes."" and wah la! On the next page at the top there is a scheme for polyurethanes, so what I am trying to say is good placement. 

Mechanism of Breakdown
Another great section. One thing I think you both need to decide on is whether you are going to use the term breakdown, degradation, or decomposition. I see them all throughout, I am not sure which one is more right, but I think that you should agree on one and use it throughout. In the second paragraph there seems to be an error in your wiki language. There is the word oxygen that looks like this: [[oxygen[[. In the paragraph following your scheme, there is a sentence explaining the challenges for enzymes to evolve to accommodate the synthetic polymers. I there really like it and I think it is full of information. Although, I think that this sentence is crucial, I also think that it could be worded better. In this same paragraph there is a sentence that starts with:""Typically, after physical processes......"" There seems to be some extra words and the sentence does not quite make sense. 

Applications 
Application section is really nice. I think that medicinal application for these is really interesting and I also think that most people will find this intriguing. I think your section is weighted toward medicinal applications, and I think that is awesome. Now the stuff I thought that could be changed: I think that the first sentence of the second paragraph could be removed completely and the paragraph would be fine. In the third paragraph there is a sentence where you use the term in vitro twice. I think that second usage could be removed. Also, I got a little confused in the example sentence about rat smooth muscle tissue. I really like the term ""holy grail"", not sure if this was intended to be a monty python reference, but it should of been. Although, I like the term holy grail, I think from a professional stance there may be other terms you could use. 

PLA- I think this s
