“…The printing of gold nanoparticles is a particularly promising approach since gold is chemically inert, displays excellent resistance to oxidants and acids, has high conductivity when thermally sintered, and it has a high affinity for thiol‐containing biomolecules . Apart of widely applied gold and silver nanoparticles, WO 3 nanoparticles were also inkjet printed on elastomers to create electrochromic energy storage systems .…”

Nanoparticles with absorption in Near-Infrared (NIR) region and subsequent efficient release of heat, are receiving great attention due to wide opportunities of applications in different fields including biotechnology and nanomedicine. However, the colloidal solutions of such nanoparticles may have limitations in effective application connected with long-term stability of nanoparticle solutions and possible re-usability. Therefore, this minireview focuses on the state-of-the art of research and application of photothermally active nanoparticles

“…Yu et al [ 146 , 147 , 148 , 149 ] compared the effects of laser type, wavelength, and power on the electrical properties and surface morphologies of sintered nano thin film. The results showed that the picosecond pulsed laser did less damage to the substrate as compared with the nanosecond pulsed laser and continuous laser.…”

Recently, nanosilver pastes have emerged as one of the most promising high temperature bonding materials for high frequency and high power applications, which provide an effective lead-free electronic packaging solution instead of high-lead and gold-based solders. Although nanosilver pastes can be sintered at lower temperature compared to bulk silver, applications of nanosilver pastes are limited by long-term sintering time (20–30 min), relative high sintering temperature (>250 °C), and applied external pressure, which may damage chips and electronic components. Therefore, low temperature rapid sintering processes that can obtain excellent nanosilver joints are anticipated. In this regard, we present a review of recent progress in the rapid sintering of nanosilver pastes. Preparation of nanosilver particles and pastes, mechanisms of nanopastes sintering, and different rapid sintering processes are discussed. Emphasis is placed on the properties of sintered joints obtained by different sintering processes such as electric current assisted sintering, spark plasma sintering, and laser sintering, etc. Although the research on rapid sintering processes for nanosilver pastes has made a great breakthrough over the past few decades, investigations on mechanisms of rapid sintering, and the performance of joints fabricated by pastes with different compositions and morphologies are still far from enough.

“…Upon further examination, a degree of variation was noted in the size of these structures and the homogeneity of their deposition at differing ablation parameters ( Figure 2). [32]. The aggregated structures apparent with a broccolilike appearance would suggest that the deposited film has a high ratio of surface area to volume, a property that is extremely desirable for their proposed application in biosensors [33].…”

As nanotechnology has developed, the creation of nanostructured surfaces has garnered attention for their uses in sensing and catalysis applications. These are however often expensive, time-consuming, and difficult to produce. In contrast, this investigation is focused on the inexpensive, environmentally friendly and fast technique of Confined Atmospheric Pulsed-laser deposition (CAP). The CAP technique has these advantages because it is an atmospheric laser-based direct deposition technique. Herein, the CAP process is examined in an effort to better understand the process and to begin determining the means to control the properties of the nanostructured surfaces produced by varying the laser fluence and the scan strategy during the ablation. During this investigation, a Nd:YAG laser was applied to deposit gold nanostructures directly onto a polymer substrate. The plasmonic properties and morphologies of the surfaces were examined using UV-Vis spectroscopy and Scanning Electron Microscopy (SEM) respectively. A mathematical model was developed to describe the size and dispersity of the structures deposited and the variation of the position and size of the spectral plasmon peaks in response to the sample processing parameters, with the aim of allowing for a degree of control over these properties and gaining some understanding of the mechanism of this deposition process.
