Fingerprint (FP) is a global mark used for personal identification. This study reviews recent latent fingerprint (LFP) enhancement techniques including metal oxides, multi-metal deposition (MMD-I/II/SMD/Au-ASP), optical, chemical, physical, and physicochemical. Furthermore, analytical techniques involved in identification, evaluation, and determination of pieces of evidence, and perpetrators including the SEM, TEM, UV-Vis, IR/NIR, SERS, SKP, DLS, MALDI-MSI, and TD analysis were also discussed. Among numerous LFP enhancement techniques, the application of chemical methods in combination with optical techniques has a greater place to recover FPs with sufficient quality. However, instead of using such a complex and costly enhancing agent, nowadays nanotechnology is using specific techniques used for visualizing, inspecting, gathering, and analyzing trace evidence at the scene of a crime. To indicate using simple metal oxides such as ZnO that have superior fluorescent properties and also that consider both the surface and cost of the materials, enhancement of the LFP is functioning.

“…Metal organic frameworks (MOFs) offer highly selective and sensitive detection of H 2 S because of possessing chemical stability, custom tuning of porosity and functionalities, and various pre- or post-synthetic modifications to the structural framework [ 173 ]. Guo et al [ 174 ] synthesized a MOF material named as Zr(TBAPy) 5 (TCPP) using a solvothermal method, where Zr is the metal center, and 1,3,6,8-tetra(4-carboxylphenyl) pyrene (TBAPy) and tetrakis(4-carboxyphenyl) porphyrin (TCPP) act as double linkers. The prepared Zr(TBAPy) 5 (TCPP) exhibited well-shaped shuttle structures with a particle size of about 100 nm as seen from the transmission electron microscope (TEM) image ( Figure 14 D).…”

Toxic gases, such as NOx, SOx, H2S and other S-containing gases, cause numerous harmful effects on human health even at very low gas concentrations. Reliable detection of various gases in low concentration is mandatory in the fields such as industrial plants, environmental monitoring, air quality assurance, automotive technologies and so on. In this paper, the recent advances in electrochemical sensors for toxic gas detections were reviewed and summarized with a focus on NO2, SO2 and H2S gas sensors. The recent progress of the detection of each of these toxic gases was categorized by the highly explored sensing materials over the past few decades. The important sensing performance parameters like sensitivity/response, response and recovery times at certain gas concentration and operating temperature for different sensor materials and structures have been summarized and tabulated to provide a thorough performance comparison. A novel metric, sensitivity per ppm/response time ratio has been calculated for each sensor in order to compare the overall sensing performance on the same reference. It is found that hybrid materials-based sensors exhibit the highest average ratio for NO2 gas sensing, whereas GaN and metal-oxide based sensors possess the highest ratio for SO2 and H2S gas sensing, respectively. Recently, significant research efforts have been made exploring new sensor materials, such as graphene and its derivatives, transition metal dichalcogenides (TMDs), GaN, metal-metal oxide nanostructures, solid electrolytes and organic materials to detect the above-mentioned toxic gases. In addition, the contemporary progress in SO2 gas sensors based on zeolite and paper and H2S gas sensors based on colorimetric and metal-organic framework (MOF) structures have also been reviewed. Finally, this work reviewed the recent first principle studies on the interaction between gas molecules and novel promising materials like arsenene, borophene, blue phosphorene, GeSe monolayer and germanene. The goal is to understand the surface interaction mechanism.

“…MOFs also belong to another class of porous materials with uniform pore size are called molecular sieves (Caro, 2016; Liu et al, 2018). Furthermore, fluorescent MOFs (Allendorf, Bauer, Bhakta, & Houk, 2009) have shown potential applications in sensing of ions (Zhao, Yang, Liu, & Ma, 2016), gases (Guo, Wang, & Cao, 2018; Lin, Liu, Ye, Li, & Zhang, 2016), and vapors (Du et al, 2018; Zhang et al, 2019).…”

Two‐dimensional (2D) metal organic frameworks (MOFs), are an emerging class of layered nanomaterials with well‐defined structure and modular composition. The unique pore structure, high flexibility, tunability, and ability to introduce desired functionality within the structural framework, have led to potential use of MOFs in biomedical applications. This article critically reviews the application of 2D MOFs for therapeutic delivery, tissue engineering, bioimaging, and biosensing. Further, discussion on the challenges and strategies in next generation of 2D MOFs are also included.
