“…Application of nanoparticle treatment makes it possible to significantly reduce the size of the tumor before surgical resection and is an important milestone towards the ultimate ability of complete and irreversible tumor resolution without surgery. This ability has been demonstrated in animal trials and is presently at the stage of human clinical trials [35] [36].…”

To cite this version:M G Kong, M Keidar, K Ostrikov. Plasmas meet nanoparticleswhere synergies can advance the frontier of medicine. Journal of Physics D: Applied Physics, IOP Publishing, 2011, 44 (17) AbstractNanoparticles and low-temperature plasmas have been developed, independently and often along different routes, to tackle the same set of challenges in biomedicine. There are intriguing similarities and contrasts in their interactions with cells and living tissues, and these are reflected directly in the characteristics and scope of their intended therapeutic solutions, in particular their chemical reactivity, selectivity against pathogens and cancer cells, safety to healthy cells and tissues, and targeted delivery to diseased tissues. Time has come to ask the inevitable question of possible plasma-nanoparticle synergy and the related benefits to the development of effective, selective, and safe therapies for modern medicine. This perspective article offers a detailed review of the strengths and weakenesses of nanomedicine and plasma medicine as a stand-alone technology, and then provides a critical analysis of some of the major opportunities enabled by synergising the nanotechnology and the plasma technology. It is shown that the plasma-nanoparticle synergy is best captured through the plasma nanotechnology and its benefits for medicine are highly promising.

Tailoring the Lasing Modes in Semiconductor Nanowire Cavities Using Intrinsic Self-Absorption

Understanding the optical gain and mode-selection mechanisms in semiconductor nanowire (NW) laser is key to the development of high-performance nanoscale oscillators, amplified semiconductor/plasmon lasers and single photon emitters, etc. Modification of semiconductor band structure/bandgap through electric field modulation, elemental doping or alloying semiconductors has so far gained limited success in achieving output mode tunability of the NW laser. One stifling issue is the considerable optical losses induced in the NW cavities by these extrinsic methods that limit their applicability. Herein we demonstrate a new optical self-feedback mechanism based on the intrinsic self-absorption of the gain media to achieve lowloss, room-temperature NW lasing with a high degree of mode selectivity (over 30 nm). The cadmium sulfide (CdS) NW lasing wavelength is continously tunable from 489 nm to 520 nm as the length of the NWs increases from 4 to 25 m. Our straightforward approach is widely applicable in most semiconductor or semiconductor/plasmonic NW cavities. Single crystalline semiconductor Fabry-Pé rot or whispering gallery nanowire (NW) cavity possessing naturally formed flat facets for good optical feedback is an ideal gain media for light amplification. [1][2][3][4][5][6][7][8][9][10] They are considered as one of the most important and promising routes to realizing miniaturized nanolasers and amplifiers. [11][12][13] Recent groundbreaking work on utilizing semiconductor NW cavities to compensate the damping loss and amplify the collective electron oscillations in plasmon nanocavities has kindled even greater interests in this field. 2,13,14 For practical applications, the ability to tailor the NW cavity mode is essential for developing multi-color miniaturized lasers, and critical for optimizing the resonant energy transfer between the cavity and the coupled system. 15 For a II-VI or III-V NW Fabry-Pé rot cavity, it is generally accepted that the output laser wavelength is determined by the bandgap of semiconductor NW. 11 To date, there is only limited success in tuning the optical cavity modes through (a) electric field modulation; and (b) elemental doping of the semiconductors. 6,9,16 In the former approach where the bandgap is modulated via the Franz-Keldysh or Stark effects, the NW cavities are highly susceptible to damage and only narrow tunability around 10 nm is demonstrated; 17 while in the later approach, the NW cavities are prone to structural defects induced by the dopants, thereby restricting the cavity gain. Keywords: Cadium sulfide, nanowire cavity, Urbach tail, Waveguide, lasingThough broadband tunable lasing wavelengths spanning 100 nm or more have been demonstrated in ternary semicondutor NW cavities, 18 cavity gain is however limited by the structural defects formed during the growth phase. 7,16 Use of extrinsic optical feedback such as photonic crystals to achieve better mode selectivity is another approach. However, the high-cost and complicated fabrication required, together with th...

Optics is one of the most important courses for students whose majors are optics-related. In this article, we would like to share our teaching experiences of introducing the newest holographic display technologies which are understandable for undergraduate students. According to the feedbacks from the students, it can stimulate the students' interest in the course by introducing the up-to-date research achievements. And the students can understand the basic concepts and principles quite well while we link them with the scientific frontier. We think it is important for the course instructors to keep in steps with the discipline frontier, thus we can introduce the newest contents to the students. The teaching mode is more flexible, the teaching process will be more attractive.
