Microscopy and Microanalysis 2007 will be the premiere meeting of the year for scientists and technologists worldwide who use microscopy and microanalysis in their research. We believe that there will be much to interest each of you, and we hope that you will take advantage of the unique interdisciplinary nature of the Microscopy and Microanalysis meetings as a way to broaden your knowledge by learning about techniques and applications that may be somewhat outside your main research focus. We have aimed to give equal emphasis to applications in both biological and physical science, while soliciting symposia that reflect current and emerging trends in microscopy and microanalysis, and in the development of associated instrumentation. We look forward to meeting and interacting with as many of you as possible at Fort Lauderdale.
