CoFe2O4 Based Black Magnetic Fingerprint Powder: Development, Analysis and Applications of Nanoparticles in Decipherment of Latent Fingerprints

Vaishnavi N Halarnkar, Anagha S Nair, Debaditya Mandal, Rajneesh Kumar, Sandeep Munjal

Herein, we report the synthesis of magnetic cobalt ferrite (CFO) nanoparticles, to study its application for the development of latent fingerprints using rapid and cost-effective combustion method. X-ray diffraction (XRD) was used for the structural characterization, which confirmed the pure phase of synthesized nanoparticles. The CFO nanoparticles were used to develop latent fingerprints over a non-porous surface. The developed fingerprints were observed under a stereomicroscope and a large number of pores could be identified and differentiated as open or closed pores, and the average pore size has been calculated. All the obtained results were compared to the results obtained using commercial black magnetic latent fingerprint powder, which established the superiority of synthesized CFO nanoparticles. Current study may pave the path for the development of a potential black magnetic fingerprint powder, which can effectively reveal the fine features of latent fingerprints after development.

Forensic Odontology and Nanotechnology: Transforming Identification, Investigation, and Anthropological Research

Misty Advani, Saloni Sharma

Forensic science has significantly evolved in the last few years, with advancements in various disciplines, including forensic odontology and forensic nanotechnology. In Legal & Administrative Order, forensic odontology plays a pivotal role for personal identification whereas nanotechnology has opened new avenues for investigation and anthropological research. This current review paper uncover the potential harmony between forensic odontology and nanotechnology, highlighting their game changing potential on identification, and investigation, as well as anthropological research. Forensic odontology, the study of dental science has long been an crucial component of forensic science and its commencement. It has proven to be stable and meticulous method for identification, particularly in cases where traditional methods, such as Fingerprint identification and Genetic sequencing, are not realistic and has been indispensable in solving various criminal cases, including sexual assault, suicide attempts and disaster victim identification of human remains. On top of that anthropologists play a crucial role in using dental traces through facial overlay methods, skeletal approximation, unique cranial characteristics, sinus variations, and bone remains. On the other hand, nanotechnology, the manipulation of matter at the nanoscale, which is generally defined as the range of 1 to 100 nanometers, has revolutionized various fields, including forensic science. This paper explores the converging fields of forensic odontology and nanotechnology, examining how these developments are revolutionizing the way we approach identification, investigation, and anthropological research.

From Yesterday to Tomorrow: Exploring Methods in Bite Mark Analysis

Sarang Damle, Nikhil Rathod

Background: Taking account from the National Crime Records Bureau there were 31,677 cases of sexual assault registered in the single year 2021, which implies roughly 80 cases daily. To address such serious crimes forensic professionals must be aware and focus on traditional pieces of evidence such as DNA, Seminal Stains, bitemarks or struggle marks, and other confirming shreds of evidence. Bite mark analysis is a vital component of forensic investigations, offering a distinct form of evidence in criminal proceedings. By leveraging the uniqueness of dental structures, bite marks can contribute significantly to personal identification and the resolution of crimes involving assault, sexual offenses, and homicide. Main Body: We portrayed the collection, packaging, and preservation methods of bitemark, and included the DNA extraction from saliva. Structural distinctive features which are used to differentiate human dentition from animal dentition. Accidental and intentional crimes then easily distinguished. In the case of wildlife forensics also bitemarks have wide scope and importance for determination of species and tagging them with their habitat. Short Conclusion: In recent times with rapid evolution in computational capabilities, we are able to use complex applications of computer science for the purpose of three-dimensional comparison of bitemarks, use of digital image processing and image modifications. the statement on which most of us will agree is Bite marks are always being interest of investigators in cases of sexual assault and child abuse.

Revolutionizing Digital Forensics: The Role of AI and ML in Evidence Analysis

Niza Italiya, Jay Makwana, Bhumi Thakor, Harsh Panchal

Evidence Analysis plays a valuable role in any investigation carried out for individual or organizations post criminal activities, leveraging AI/ML extensively which helps in automating repetitive and laborious tasks aiding investigators to focus on the significant course of action. AI/ML came up for significant transformations to the field by various techniques for simplification. Advancements allowed experts to dedicate time and other resources to critical aspects of investigation instead. Modern methodologies offers solutions to variegated domains of digital forensics, such as network analysis, device forensics, cybercrime investigations and many more. This paper gives you an overview of how AI and ML techniques can be implemented in digital forensics, by use of different approaches. For example, NLP can be used to analyse large volume of text data, extracting information or identifying patterns. AI driven image and video surveillance tools can detect anomalies, recognize faces or analyse patterns in recordings of live feed. Pattern recognition helps in identifying recurring events or correlations in evidence, like tracing data or detecting frauds in or during cyberattacks. All these benefits come with challenges including data quality problems, bias in algorithm and limitations in complex dataset handling. Inefficiencies in interpreting results due to the black box nature of some AI models that lack the ability of explanation are also encountered by experts. To address these challenges, adopting to advanced algorithms, integration of human expertise with AI tools and ensuring continuous learning to refine models in required. AI's computational power when combined with human insight creates a robust framework for digital forensics.

Role of Semiconductor Oxides in Forensic Sciences: A Review

Priyanka Nehla, Vidit Pandey

Semiconductor oxides are playing an important role in the advancing modern forensic science, offering sensitive, selective, and rapid analyses. At nanoscale, they have a high surface area, unique chemical and physical properties, versatility, tunable optical, electrical, and magnetic characteristics. Applying different characterization techniques with semiconductor oxides on the nano-forensic evidences can provide the accurate and efficient results. Key semiconductor oxides such as ZnO, TiO2, CuO, or Iron oxides can be used in drugs/toxic powder detection, gun powder/explosive residue analyses, fingerprint detection, and other forensic applications as photocatalysis, artificial olfactory system, powder suspension, auxiliary agent, colorimetric, gas, and electrochemical sensing.

Ultrasonication-Assisted Cell Lysis of Chicken Liver Cells for DNA Isolation and Adsorption-Elution Studies on CoFe2O4@ZnO

Dr. Saroj Babar, Aman Verma, Shreya Naik

Extracting nucleic acids for identification of suspects in the field of forensic science is still an arduous assignment and requires less intensive and labour free protocols. Liver tissue of mammals is known to contain high density of nuclei which leads to extraction of high amount of genetic material. Therefore, DNA extraction has been performed using newly developed lysis method with conventional method as well as the nanocomposites were brought in use to check the adsorption and elution capabilities. The developed magnetic nanocomposites CFO@ZnO were synthesized using solution combustion method and co-precipitation method and characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). The newly developed CFO@ZnO nanocomposites show exceptional quality of DNA extraction by the revamped approach of lysing the cells as compared to the traditional method of cell lysis. This cutting-edge method is cost efficient as well as less time consuming with superior performance and thus proves to be an updated strategy of cell lysis.
