Biochemical Applications In Forensics


Book Description

Forensic biochemistry is the branch of biochemistry that deals with solving crimes. The biochemical method of DNA fingerprinting is often used for this kind of study. Since sequencing technology became available, genetic markers might be used to uniquely identify individuals within a group. The employment of such methods, however, requires extreme care due to the gravity of the consequences. The field of forensics makes use of scientific methods to provide evidence in court. Crime is usually involved, though not always. Forensic biochemists are sometimes called upon to investigate the history of an unknown material, establish biological kinship between individuals, or monitor the progression of an illness. A career in forensic biochemistry requires dedication and perseverance, but it pays off in the end. To do well in this field, one has not just to be ethical and truthful but also patient and detail-oriented. This book covers all the topics related to biochemistry in forensics science like Basic Principles and Significance of Forensic Science, scene of investigation, Biological science and its application in investigation, Establishment of identity of individuals, Biochemical basis for determination of cause of death, Chemical science and its application in investigation, Blood splatter analysis, Recent advances in forensics, Facial reconstruction, DNA Finger Printing, Mass disaster and other forensic case work etc

The broad subject coverage includes spectroscopic analysis techniques in various wavelength regimes, gas chromatography, mass spectrometry, electrochemical detection approaches, and imaging techniques, as well as advanced biochemical, DNA-based identification methods. The result is a unique collection of hard-to-get data that is otherwise only found scattered throughout the literature.




Forensic DNA Applications


Book Description

Forensic DNA Applications: An Interdisciplinary Perspective was developed as an outgrowth of a conference held by the International Society of Applied Biological Sciences. The topic was human genome–based applications in forensic science, anthropology, and individualized medicine. Assembling the contributions of contributors from numerous regions around the world, this volume is designed as both a textbook for forensic molecular biology students and a reference for practitioners and those in the legal system. The book begins with the history and development of DNA typing and profiling for criminal and civil purposes. It discusses the statistical interpretation of results with case examples, mitochondrial DNA testing, Y single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs), and X SNP and STR testing. It also explores low copy number DNA typing, mixtures, and quality assurance and control. The second section examines the collection and preservation of biological evidence under a variety of different circumstances and the identification of human remains—including in mass disaster settings. It discusses applications to bioterrorism investigations, animal DNA testing in criminal cases, pedigree questions and wildlife forensic problems, applications in forensic entomology, and forensic botany. The third section explores recent developments and new technologies, including the rigorous identification of tissue of origin, mtDNA profiling using immobilized probe strips, chips and next-generation sequencing, the use of SNPs to ascertain phenotypic characteristics, and the "molecular autopsy" that looks at aspects of toxicogenetics and pharmacogenetics. The book concludes with a discussion on law, ethics, and policy. It examines the use of DNA evidence in the criminal justice system in both the United States and Europe, ethical issues in forensic laboratory practices, familial searches, DNA databases, ancestry searches, physical phenotyping, and report writing. The contributors also examine DNA applications in immigration and human trafficking cases and international perspectives on DNA databases.

DNA Technology in Forensic Science


Book Description

Matching DNA samples from crime scenes and suspects is rapidly becoming a key source of evidence for use in our justice system. DNA Technology in Forensic Science offers recommendations for resolving crucial questions that are emerging as DNA typing becomes more widespread. The volume addresses key issues: Quality and reliability in DNA typing, including the introduction of new technologies, problems of standardization, and approaches to certification. DNA typing in the courtroom, including issues of population genetics, levels of understanding among judges and juries, and admissibility. Societal issues, such as privacy of DNA data, storage of samples and data, and the rights of defendants to quality testing technology. Combining this original volume with the new update-The Evaluation of Forensic DNA Evidence-provides the complete, up-to-date picture of this highly important and visible topic. This volume offers important guidance to anyone working with this emerging law enforcement tool: policymakers, specialists in criminal law, forensic scientists, geneticists, researchers, faculty, and students.




Light in Forensic Science


Book Description

The identification and quantification of material present and collected at a crime scene are critical requirements in investigative analyses. Forensic analysts use a variety of tools and techniques to achieve this, many of which use light. Light is not always the forensic analyst’s friend however, as light can degrade samples and alter results. This book details the analysis of a range of molecular systems by light-based techniques relevant to forensic science, as well as the negative effects of light in the degradation of forensic evidence, such as the breakage of DNA linkages during DNA profiling. The introductory chapters explain how chemiluminescence and fluorescence can be used to visualise samples and the advantages and limitations of available technologies. They also discuss the limitations of our knowledge about how light could alter the physical nature of materials, for example by breaking DNA linkages during DNA profiling or by modifying molecular structures of polymers and illicit drugs. The book then explains how to detect, analyse and interpret evidence from materials such as illicit drugs, agents of bioterrorism, and textiles, using light-based techniques from microscopy to surface enhanced Raman spectroscopy. Edited by active photobiological and forensic scientists, this book will be of interest to students and researchers in the fields of photochemistry, photobiology, toxicology and forensic science.

Microbial Forensics


Book Description

Microbial Forensics is a rapidly evolving scientific discipline. In the last decade, and particularly due to the anthrax letter attacks in the United States, microbial forensics has become more formalized and has played an increasingly greater role in crime investigations. This has brought renewed interest, development and application of new technologies, and new rules of forensic and policy engagement. It has many applications ranging from biodefense, criminal investigations, providing intelligence information, making society more secure, and helping protect precious resources, particularly human life. A combination of diverse areas is investigated, including the major disciplines of biology, microbiology, medicine, chemistry, physics, statistics, population genetics, and computer science. Microbial Forensics, Second Edition is fully revised and updated and serves as a complete reference of the discipline. It describes the advances, as well as the challenges and opportunities ahead, and will be integral in applying science to help solve future biocrimes. - A collection of microbiology, virology, toxicology and mycology as it relates to forensics, in one reference - New and expanded content to include statistical analysis of forensic data and legal admissibility and the standards of evidence, to name a few - Includes research information and application of that research to crime scene analysis, which will allow practitioners to understand and apply the knowledge to their practice with ease
