“…In comparison, the localized surface plasmon resonances (LSPR) provide metal‐based particles with strong optoacoustic signal generation and photo‐stability, and thereby constitute the “gold standard” for OAI . Recently, gold nanoparticles have attracted significant research interest as nanosized contrast agents in OAI owing to their biocompatibility, unique optical absorption properties, and photothermal (PT) effects …”

A functional cancer theranostic nanoplatform is developed, specifically tailored toward the optoacoustic modality by combining gold nanorods with DNA nanostructures (D-AuNR). DNA origami is used as an efficient delivery vehicle owing to its prominent tumor-targeting property. The D-AuNR hybrids display an enhanced tumor diagnostic sensitivity by improved optoacoustic imaging and excellent photothermal therapeutic properties in vivo.

“…26,27 It is known that such long rods are efficient light scatterers so there is a balancing act between the absorption and scattering pathways and the greatest potential may actually lie in using NIR absorbing rods for bio-imaging. Rods could be fabricated that absorb in the mid-infrared, allowing even lower temperature thermal imaging spectra to be obtained.…”

Thermal energy harvesting near-infrared radiation and accessing low temperatures with plasmonic sensors

2015

Near-infrared (NIR) thermal energy harvesting has been demonstrated for gold nanorods (AuNRs), allowing concentration dependent, ppm-level, gas detection of H2, CO, and NO2 at 500 °C without using a white light source. Part-per-million detection capabilities of the gold nanorods are demonstrated with a factor of 11 reduction in collection times in the NIR as compared to measurements made in the visible light region. Decreased collection times are enabled by an increase in S : N ratio, which allowed a demonstration of selectivity through the use of both full spectral and a reduced spectral-based principal component analysis. Furthermore, low temperature thermal imaging spectra have been obtained at sample temperatures ranging from 275-500 °C, showing the possibility of energy harvested gas sensing at lower temperatures. These findings are promising in the area of miniaturizing plasmonic gas sensing technology and integration in areas such as gas turbines.

Owing to their unique physicochemical properties, nanoparticles are used in a variety of ways in the field of cancer treatment, including imaging, drug delivery, and photothermal and photodynamic therapies. The fascinating properties of nanoparticles are determined by their size, morphology, and constituent elements, and various synthetic methods and post-synthetic techniques have been applied to control these factors. Herein, we present examples of shape and composition control through galvanic replacement, a technique that exploits redox potential differences between elements to induce spontaneous ion-exchange and highlight its specific contributions to cancer treatment applications. The present article identifies the recent advances in nanoparticle formation techniques and discusses the future outlook of the field.
