The current status of the use of nanoparticles for photothermal treatments is reviewed in detail. The different families of heating nanoparticles are described paying special attention to the physical mechanisms at the root of the light-to-heat conversion processes. The heating efficiencies and spectral working ranges are listed and compared. The most important results obtained in both in vivo and in vitro nanoparticle assisted photothermal treatments are summarized. The advantages and disadvantages of the different heating nanoparticles are discussed.

“…The roughness of CNTs has great relation with that of the hole wall of AAO template. In previously reported CVD experiments [ 12 ], the temperature of the system was increased quickly to reaction temperature and then immediately started the CVD experiment. In this process, the temperature directly rose from room temperature to reaction temperature; in other words, the sample has always been in a rapid heat treatment condition.…”

“…In recent years, CNTs can be prepared mainly by arc discharge [9,10], laser evaporation [11], and chemical vapor deposition (CVD) [12,13]. Due to their mature preparation methods and outstanding properties, CNTs have been extensively exploited in a range of potential applications including nanodevices [14], sensor [15], field emission [16,17], battery [18], and hydrogen storage [19].…”

“…Carbon nanotubes (CNTs) [ 1 , 2 ], a typical one-dimensional nanostructure, have attracted great attention due to their unique combination of electronic, mechanical, chemical, and thermal properties [ 3 - 8 ]. In recent years, CNTs can be prepared mainly by arc discharge [ 9 , 10 ], laser evaporation [ 11 ], and chemical vapor deposition (CVD) [ 12 , 13 ]. Due to their mature preparation methods and outstanding properties, CNTs have been extensively exploited in a range of potential applications including nanodevices [ 14 ], sensor [ 15 ], field emission [ 16 , 17 ], battery [ 18 ], and hydrogen storage [ 19 ].…”

Highly uniform hole spacing micro brushes based on aligned carbon nanotube arrays

Highly uniform hole spacing micro brushes were fabricated based on aligned carbon nanotube (CNT) arrays synthesized by chemical vapor deposition method with the assistance of anodic aluminum oxide (AAO) template. Different micro brushes from CNT arrays were constructed on silicon, glass, and polyimide substrates, respectively. The micro brushes had highly uniform hole spacing originating from the regularly periodic pore structure of AAO template. The CNT arrays, serving as bristles, were firmly grafted on the substrates. The brushes can easily clean particles with scale of micrometer on the surface of silicon wafer and from the narrow spaces between the electrodes in a series of cleaning experiments. The results show the potential application of the CNT micro brushes as a cleaning tool in microelectronics manufacture field.

“…Before the introduction of a carboncontaining gas, such as CH 4 or CO, a pre-reduction step is typically performed at increased temperatures using H 2 or NH 3 as the reducing agent. [67][68][69] H 2 typically dilutes CNT growth from CH 4 , and this process occurs at higher temperatures.…”
