Riassunto
This handbook covers the field of noninvasive biophysical methods in clinical and experimental dermatology. It is the result of a coordinated effort by some of the most prominent experts in the field. Structured to provide both educational and practical information, its value to both young researchers and senior scientists is unparalleled. All the major methods systematically cover scope, sources of error, application, and validity. Additional chapters provide research methodology and legal and ethical aspects.
