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
