“…An additional information to consider is that the indentation process is a crucial aspect of accurately determining RBCs Young Modulus parameters by AFM. As reported by Smijs et al [54] the material from which the used cantilever is made does influence the measurements, especially as the stiffness of erythrocytes increases over time.…”

"Considering the basic function of red blood cells (RBC, erythrocytes) as carriers of oxygen and carbon dioxide throughout the bloodstream, as well as their possible secondary activities, RBCs deserve more consideration. The current work attempts to serve as a summary of RBC properties, both well-established and less well-established, with a focus on pathologies and drug interactions. This review is especially important given the recent trend of employing erythrocytes as vehicles for targeted medication delivery."

Criminal activities have their footprints from time immemorial and nature of crime has drastically changed over a period of time. There is neither a geographical boundary, nor technical limitations. Moreover terrorist’s activities, drug trafficking eco-crimes, high-profile crimes, robbery hit and run cases, building collapse, petroleum products adulteration are some of latest forms of crimes. In last 20 years, scanning probe microscopes have emerged as an essential technique in various fields, and atomic force microscope (AFM) is most commonly used scanning probe technique which has shown its wide range of application in examination of various evidences encountered on crime scene. Major advantages of AFM involve its high resolution in three dimensions, and sample is not necessary to be conductive and it does not need to be operated within a vacuum. It helps in studying a large range of topographies and many types of materials can be imaged under it. Evidences such as blood, fibers, hair, soil, finger prints, gunshot residue, pollen, etc. found on crime scene at nano- or micro-level can be examined under AFM. The chapter describes applications of AFM with respect to its application in examination of evidences that can help in bringing justice.

Due to the unique properties of nanoparticles, it has gained prominence in lots of fields with extensive research being carried around it. With lots of novel applications arising from this field, Forensic science seems to be one of the fast-growing fields in nano research applications. The growing and extensive use of nanotechnology being applied in forensic investigations is promising and could soon be the tipping point in the discipline. Applications mainly have been related to evidence identification and analysis in the broad major fields in Forensic Science such as single-crystalline semiconductor CdS nano slabs for explosives detection, functionalized TiO2 nanorods for organophosphorus chemical warfare agents in Forensic Chemistry, the use of Nanopowders for latent print visualization in Forensic physics and Gold nanoparticle protein nanopore for detection of single-stranded DNA in Forensic biology. Nanotechnology has also been employed in illegal drug detection in recent times. These and other applications of Nanotechnology provides prompt and precise results with reduced methods due to the limited instruments used for analyzing evidence as well as providing sensitive and selective ways of detecting evidence. As evidence is notable in forensic investigations, nanotechnology’s use in identifying and detecting these has potential in enhancing and providing efficient and rapid means for investigations and unravelling leads into crimes. This review emphasizes some disciplines in forensic sciences in which nanotechnology is having an impact, novel methods and newly developed instruments and also takes into account its challenges as well as perspectives into the future.
