M.E. Muller Institute for Microscopy
This website is a nice primer for those who are interested in atomic-level surface imaging of biological samples with atomic force microscopy (AFM). The accompanying graphics are illustrative of what can be done and at what resolution. Note the material is a little dated (1996), but is still very useful. If one is interested in learning about biological imaging with other methods as well, it is recommended to open the home page site (http://www.mih.unibas.ch/Booklet/Booklet96/Intro/Intro.ht
Theme-Based Modular Approach for Delivering the Undergraduate Analytical Curriculum
This paper from the ABCs of Teaching Analytical Science in the journal Analytical and Bioanalytical Chemistry describes the modifications to the analytical curriculum at Butler University. The laboratory associated with the course in Quantitative Analysis was retooled to include a series of projects emphasizing report-writing, data reduction/analysis, method development, method comparison, and a guided-inquiry capstone project. The laboratory for Instrumental Analysis is a semester-long module
This article by Peter Griffiths, published in the ABCs of Teaching Analytical Science series of the journal Analytical and Bioanalytical Chemistry, will be of interest to faculty members teaching analytical or quantitative analysis courses to chemistry, biochemistry, pre-health or natural science majors. Drawing from a survey of colleges and universities in the western United States, Griffiths summarizes how the quantitative analysis course is currently being taught, highlighting difference
Atomic Spectroscopy in a Project-Based Lab
An article published in the \"ABCs of Teaching Analytical Science\" series of the journal Analytical and Bioanalytical Chemistry describes a project-based lab in which students investigate the distribution of Pb and As (from pesticides) in a contaminated apple orchard. Students have complete control of the lab, from designing a sampling strategy to using the primary literature to develop procedures for extracting the analytes and for their subsequent analysis by ICP-AES or ICP-MS.
Receptor Binding Assays
A tutorial on receptor binding assays used in bioanalysis. Both scintillation proximity assays and measurements based on fluorescence polarization are discussed. This page also features a good bibliography on related resources.
A learning module focused on principles and practice of NMR for quantitative analysis, an application less commonly associated with the technique than is structure determination. Links to simulation packages are included.
Atomic Force Microscopy
A video lecture on Atomic Force Microscopy (AFM) by Prof. Arvind Raman of Purdue University that discusses the historical development, instrumentation and operational principles of various AFM modes. The lecture is accompanied by power point slides with clear illustrative graphics. Basics are provided in the application examples with advantages and limitation discussed. Useful site to those interested in learning AFM.
