Foreword
Over the last four decades, two key factors have spurred the growth of bioinstru-
mentation: rapid advances in technology and demands by scientists to observe, measure,
and manipulate biological structures. Teams of biologists, chemists, engineers, physicists,
and computer programmers have repeatedly met the challenges of developing and adap-
ting technology to automation. The bioinstrumentation described in this book illustrates
the merging of biotechnology and automation.
Past experiences in developing bioinstrumentation are indeed prologue to the
future. In the 1950s, classic techniques of quantitative analytical biochemistry formed
the basis of instrumentation. Simple photometers recorded percent transmission of light
through a substance to measure analytics. Rigid conformance to protocol and pipetting
or measuring skills were as crucial as the instrumentation to the quality of results. In the
1960s and 1970s, cost effectiveness and ease of training to ensure technology transfer
became important goals for evolving instrumentation. The latter 1970s heralded the be-
ginning of computer-driven instrumentation and robotics to support operator adherence
ll to protocols and to replace some of the manual support techniques, like pipetting. The
growth that continued through the 1980s has led to an era of consolidation and re-
trenchment by developers of bioinstrumentation. Because of the significant investment
and long years of development before new bioinstrumentation is marketable, the fi-
nancial impact is carefully assessed before a product is launched.

Bioinstrumentation of the future will increasingly require an integration of the
sciences and engineering. Noninvasive technologies such as biosensors, which do not
require disruption of the organism during observation, measuring, and manipulation, will
be developed. Computer interface with instrumentation will increasingly assist the user.
Precision and accuracy of analyses will continue to be hallmarks for quality in bioin-
strumentation, but cost and technology transfer will justifiably be forces in determining
the instrumentation of the future.
The editors of this book have amassed a cadre of very talented authors, experts
in specific areas of bioinstrumentation. The book is appropriately divided into categories
of biotechnology and instrumentation. These are readily viewed as core technologies. For
the user of this text, this is an important premise since adaptations of current bioinstru-
mentation, as well as the evolution of next generations of bioinstrumentation, will be
based on an understanding of these core technologies.
