“…The adsorption of the MPS is confirmed by the introduction of Si 2s and Si 2p peaks at 26 In addition, two peaks associated with Si−C (878 cm −1 ) and Si−O (1047 cm −1 ) bonds are observed in all the collagen−MPS FTIR spectra in Figure 1F. 27 However, the curves for the collagen−MPS samples overlap with the control curve (Figure 1H) and there is no significant difference between them, which is due to the strong C−C stretch (1100 cm −1 ) covering the Si−O peak. 28 Therefore, we cannot conclude that MPS has affinity for collagen.…”

In this study, we aimed to examine the effect of 3-methacryloxypropyltrimethoxysilane (MPS) on dentin collagen and the impact of MPS and 10-methacryloyloxydecyl dihydrogen phosphate (MDP) together and separately on resin–dentin bonding. Eight groups of primers were prepared: control group, MDP, MPS5, MPS5 + MDP, MPS10, MPS10 + MDP, MPS15, and MPS15 + MDP. The potential interaction between MPS and collagen was assessed by molecular dynamics, contact angle measurement, zeta potential measurement, and chemoanalytic characterization using X-ray photoelectron spectroscopy, Raman spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, and ultraviolet–visible spectroscopy. Microtensile bond strength (μTBS) and nanoleakage were evaluated after 24 h or 12 months of water storage. In situ zymography was used to evaluate the enzyme activity at the bonded interface. According to chemoanalytic characterization and molecular dynamics, a weak interaction between MPS and collagen was observed. MPS enhanced the hydrophobicity and negative charge of the collagen surface ( P < 0.05). Applying an MDP-containing primer increased μTBS ( P > 0.05) and reduced fluorescence after 24 h of water storage. Water storage for 12 months decreased μTBS ( P < 0.05) and increased nanoleakage for all groups. MPS conditioning did not change μTBS and nanoleakage after 24 h of water storage or aging. The MPS10 + MDP and MPS15 + MDP groups presented more silver nitrate and μTBS decrease than the MDP group ( P < 0.05). These results indicated that MPS had a weak interaction with collagen that enhanced its surface negative charge and hydrophobicity without adversely affecting dentin bonding. However, compared to MDP alone, mixing MDP with MPS impaired their effectiveness and made the dentin bonding unstable.

“…The concept of nanotechnology was first introduced by the Nobel Laureate and quantum theorist, Richard Feynman, in his famous talk (1959) and paper (1960) “There's Plenty of Room at the Bottom,” in which the domain can be defined as the synthesis of matter on an atomic level, with sizes ranging from 1 to 100 nm. Arguably, the most obvious advantage of nanomaterials is the vast increase in surface area to volume ratio compared to the bulk material, which provides new possibilities in surface‐based science including forensic fingermark detection (Costa, Freitas, et al, 2020). Nanomaterials have structural features between those of isolated atoms and bulk macroscopic materials.…”

The majority of conventional techniques for latent fingerprint enhancement are based on chemical reactions or interactions between the developer and fingermark residue components, providing contrast between the surface and the fingerprint ridges. However, these methods might be limited by factors associated with particle size, toxicity of the reagent, selectivity, or sensitivity, that may be circumvented by the synthetic design of innovative materials based on nanoparticles or macromolecular materials, such as conducting polymers, applied as latent fingerprint developers on different surfaces and conditions. Since the structural, optical and electronic properties of the material can be tailored by its molecular scale, the size control of the developer plays an important role to improve the interaction with the latent fingermark residue and/or the surface, enhancing the color contrast and the quality of the developed image (or dactylogram). Hence, creating new reagents and strategies to apply nano-and macromolecular scale materials as latent fingermark developers constitutes an exciting rapidly expanding area, generating a wealth of new materials that lead to forensic methodologies with enhanced performance.Recent progress in the application of such materials for development of latent fingermarks present on different surfaces and subject to complex circumstances will be discussed. This will focus on the main barriers to making nanoparticles and conducting polymers viable-and occasionally preferredmaterials routinely used by forensic experts, and the potential advantages over conventional methodologies in the acquisition and analysis of crime scene evidence.
