I have been invited to do a 30 minute talk at the January AAPT meeting covering the optical trap. We've made a few modifications to the design, tried some new labs, and had quite a few students use the trap in the past year. I'll post talk details as they come up. --dapple 17:55, 23 August 2007 (EDT)

Just returned from the AAPT meeting in Syracuse, NY. I had an excellent time and greatly enjoyed talking with everyone who stopped by the poster. If you stopped by and had further questions or a material request, please contact me at dapple [at] mit [dot] edu. Thanks again for the interest and the suggestions!

Working on the revisions for the paper. Re-submission should occur in the next few weeks. Still have a few kinks to iron out. --dapple 14:24, 29 June 2006 (EDT)

The AJP paper will be submitted in the upcoming week or two. If you are anxious to start building, please contact me about getting a draft version of the article. --dapple 22:53, 26 February 2006 (EST)
