Course Outline for Forensic Physics (Including both FACT and FACT Plus Curriculums)

Forensic physics plays a crucial role in investigating various types of exhibits, from trace materials to physical patterns, with high sensitivity and specificity. Here's a rundown of some key analytical techniques used in this field.

1. Chromatography Chromatography techniques, such as two-dimensional liquid chromatography (2D-LC), are employed to separate and analyze inorganic anions, cations, and organic explosive materials from a single sample. This reduces the sample amount and analysis time, making it more efficient for evidence like explosives. Other chromatographic methods like gas chromatography (GC) and high-performance liquid chromatography (HPLC) are also widely applied for chemical separation in forensic cases.
2. Mass Spectrometry (MS) Mass spectrometry, often coupled with chromatography, measures mass-to-charge ratios of ions to identify and quantify molecules in forensic samples such as narcotics, explosives, or trace chemicals.
3. Spectroscopy Spectroscopic methods, including UV-visible, infrared (IR), and other spectrophotometric techniques, are used to identify and quantify substances based on their interaction with light. These can be used for analyzing chemical and physical exhibits.
4. Chemical Enhancement and Pattern Analysis Forensic physics also involves the analysis of physical evidence such as bloodstain patterns. Chemical enhancement techniques help reveal invisible blood traces on surfaces, while accurate interpretation of bloodstain shapes, directionality, and impact angles is crucial in reconstructing events.
5. Physical Science Applications Broader forensic physics applies principles of mechanics, optics, and thermodynamics to examine physical evidence, including ballistics (trajectory and impact analysis), fracture analysis, and material properties to assist law enforcement and court presentations.

These techniques are often used in combination depending on the exhibit type—chemical (e.g., explosives, narcotics), biological (e.g., blood), or physical (e.g., fracture patterns)—to provide a thorough and scientifically valid analysis.

In addition to these, other techniques like nano-science & nano-technology, CCTV analysis, motorcycle accident investigation, road evidence analysis, fibre analysis, paint analysis, and molecular toxicology of some poisons are also integral parts of forensic physics.

2. Forensic linguistics contributes to analyzing written messages and verbal communications to help identify authors or resolve disputes, such as in ransom notes or cases of plagiarism.
3. At crime scenes, forensic science combines various disciplines, like DNA analysis, fingerprinting, and anthropology, to gather evidence, reconstruct events, and identify suspects.
4. For an accurate diagnosis of medical-conditions related to health-and-wellness in autopsies, forensic pathology employs advanced imaging techniques and microscopic analysis.
5. Digital forensics extracts and analyzes digital data from devices to investigate crimes such as data theft, cyber extortion, or online fraud, utilizing software and algorithms to recover deleted files or trace IP addresses.
6. Forensic toxicology analyzes the presence, concentration, and effects of drugs, toxins, or nitrates in biological specimens, contributing to investigation and understanding the involvement of these substances in deaths or impairments.
7. Cyber forensics extends the remit of digital forensics, addressing threats and investigating cases within the realm of digital technology, including malware, ransomware, and network intrusions, helping organizations maintain their security and operate with integrity.
