The book is also structured in a way that can serve as a textbook or a primary reference book for anadvancedanalyticalchemistrycourseoraspecialtopiccourseforgraduateandsenior undergraduate students. I discovered the difficulty of finding effective teaching materials andsuitablereferencebooksformystudentsandcollaboratorswhileItaughtthecourseand engagedjointresearchprojectswithcolleaguesinthedepartmentofbiologicalsciencesand engineering. Ultrasensitive detection plays a vital role in advancing analytical chemistry and has been a primary driving force for the development of new analytical instrumentation and methodology. As analysis of biological samples (e.g., genomics, proteomics) and living systems(e.g.,cellularandsubcellularfunction)becomesmoredemanding,newplatforms of ultrasensitive analysis using multiplexing, single nanoparticle sensing, nano-fluidics, and single-molecule detection have emerged and have become indispensable tools to ad- vancebiological,biomedical,andbiomaterialssciencesandengineering.Furthermore,the emergingresearchfieldofnanoscienceandnanotechnologyprovidesnewpossibilitiesfor developmentofnewanalyticaltoolsandinstrumentationforbioanalysis.Forexample,the uniquepropertiesofnanoparticlesofferenormousopportunitiestodevelopnewprobesfor real-time in vivo and in vitro imaging and sensing of individual biomolecules with sub- 100-nm spatial resolution and millisecond to nanosecond time resolution. Such powerful capabilitieswillleadtothedevelopmentofnewanalyticaltechniquestoimprovedisease diagnosisandtreatment,aswellastoadvanceourfundamentalunderstandingofimportant phenomenasuchasmembranetransport,geneexpression,enzymeactivities,andintracel- lularandintercellularsignaling.Itisundeniablethatanalyticalchemistryhasevolvedtobe avitalplayerinallcutting-edgescientificresearchfields.
