- ПубликацияТолько метаданныеTemperature oscillations during photoinduced heating of aqueous suspensions of silicon nanoparticles(2021) Belov, V. S.; Bobkov, E. A.; Oleschenko, V. A.; Kabashin, A. V.; Timoshenko, V. Yu.; Белов, Владимир Сергеевич; Бобков, Егор Андреевич; Кабашин, Андрей Викторович; Тимошенко, Виктор Юрьевич© 2021 Institute of Physics Publishing. All rights reserved.Temperature oscillations (pulsations) were detected in aqueous suspensions of silicon (Si) nanoparticles NPs under laser irradiation with highly absorbed light. The temperature pulsation frequency was found to depend on the NPs concentration in suspension and laser irradiation power. The observed phenomenon is assumed to be caused by the local overheating of Si NPs close to the boiling point of water, while the average heating of the surrounding liquid was insignificant. The observed phenomenon is discussed in view of potential applications in local photo-induced hyperthermia of cancer.

- ПубликацияТолько метаданныеEffect of Oxygen on Colloidal Stability of Titanium Nitride Nanoparticles Synthesized by Laser Ablation in Liquids(2021) Tikhonowski, G. V.; Popova-Kuznetsova, E. A.; Aleshchenko, Y. A.; Klimentov, S. M.; Kabashin, A. V.; Popov, A. A.; Тихоновский, Глеб Валерьевич; Попова-Кузнецова, Елена Алефтиновна; Алещенко, Юрий Анатольевич; Климентов, Сергей Михайлович; Кабашин, Андрей Викторович; Попов, Антон Александрович© 2021, Allerton Press, Inc.Abstract: The effect of oxygen existing in an ablation medium during synthesis of titanium nitride (TiN) nanoparticles (NPs) by pulsed laser ablation in liquid (PLAL) on colloidal stability of obtained solutions was studied. It was shown that an increase in the oxygen content both incorporated in liquid molecules and in the form of dissolved gas increases the colloidal stability of synthesized NPs. The results obtained extend the range of available methods for developing new nanomaterials due to control of colloidal stability of laser-synthesized NPs.
- ПубликацияТолько метаданныеBare laser-synthesized plasmonic Au and TiN nanoparticles as functional additives to polymer nanofiber platforms for tissue engineering applications(2021) Al-Kattan, A.; Kabashin, A. V.; Кабашин, Андрей Викторович© 2021 Institute of Physics Publishing. All rights reserved.Exhibiting strong optical absorption in the visible - near-infrared, plasmonic nanomaterials can be used as transducers in optical biosensing, contrast agents in bioimaging and synthesizers of photothermal therapy. Such functionalities promise their employment as functional elements in tissue engineering platforms, but such applications typically require ultraclean nanomaterials to minimize toxicity problems, which is not easy using conventional chemical synthesis routes. We recently demonstrated the possibility of fabricating ultraclean bare (ligand-free) plasmonic Au and TiN nanoparticles by ultrashort laser ablation in liquid ambient. Exempt of any toxic contaminants and exhibiting a series of imaging and therapeutic functionalities, these nanomaterials present promising objects for various biomedical applications. Here, we review our recent progress in the co-electrospinning of laser-synthesized Au and TiN nanoparticles with polymers to form functionalized matrices for tissue engineering.

- ПубликацияТолько метаданныеPhotoluminescent Si-based nanocrystals prepared by pulsed laser ablation in low-pressure helium-nitrogen mixtures for biomedical applications(2020) Kharin, A. Y.; Fronya, A. A.; Antonenko, S. V.; Karpov, N. V.; Derzhavin, S. I.; Dombrovska, Y. I.; Garmash, A. A.; Kargin, N. I.; Klimentov, S. M.; Timoshenko, V. Y.; Kabashin, A. V.; Фроня, Анастасия Андреевна; Антоненко, Сергей Васильевич; Гармаш, Александр Александрович; Каргин, Николай Иванович; Климентов, Сергей Михайлович; Тимошенко, Виктор Юрьевич; Кабашин, Андрей Викторович© 2020 SPIE.Nanocrystalline silicon (Si) films were synthesized by nanosecond laser ablation of crystalline Si targets in low-pressure helium (He) and nitrogen (N2) gas mixtures. Photoluminescence (PL) spectra of the prepared samples were found to depend on the He/N2 ratio in the gas mixture. The ablation pure He atmosphere allowed us to prepare Si nanocrystals (NCs) exhibiting a PL band in red-near-IR range, while samples prepared in the presence of N2 exhibited a strong PL band with maximum in the green-yellow region. Such a modification of PL properties can be explained by the presence of amorphous Si oxynitride (a-SiNxOy) on the surface of Si-NCs. Structural studies of the prepared samples by means of the scanning electron microscopy revealed different morphology for Si-NCs produced under different gas mixtures. After treating of the films by ultrasound and dispersing in water, Si-NCs can be used as novel biodegradable markers for bioimaging, while the observed spectral tailoring effect makes possible an adjustment of the PL emission of such markers to a concrete bioimaging task.
- ПубликацияТолько метаданныеFourier nanotransducers for phase-sensitive plasmonic biosensing(2020) Kravets, V. G.; Wu, F.; Imaizumi, S.; Kabashin, A. V.; Shipunova, V. O.; Deyev, S. M.; Grigorenko, A. N.; Кабашин, Андрей Викторович; Деев, Сергей Михайлович© 2020 SPIE.We present phase-responding Fourier nanotransducers based on plasmonic metamaterials for ultrasensitive control of dynamic characteristics of 2D materials and functional biosensing interfaces. These nanotransducers are designed in such a way that they can confine light in 2D plane contacting with a probed ultrathin sample, gathering information about its properties, and then transmitting the information into discrete optical beams with amplified phase relations. To demonstrate their potential of Fourier transducers in biosensing, we designed Fourier nanotransducers based on periodic gold nanostructures and applied it in a newly developed protocol for the detection of important antibiotic chloramphenicol (CAP). Such biosensing tests showed the lower detection limit at fg mL-1 level, which several orders of magnitude better than reported in the literature. The implementation of Fourier nanotransducers opens new opportunities for a radical improvement of current state-of-the art plasmonic biosensing technology.
- ПубликацияТолько метаданныеColloidal samarium oxide nanoparticles prepared by femtosecond laser ablation and fragmentation for nuclear nanomedicine(2020) Duflot, V. R.; Popova-Kuznetsova, E.; Tikhonowski, G.; Popov, A. A.; Deyev, S. M.; Klimentov, S. M.; Zavestovskaya, I. N.; Prasad, P. N.; Kabashin, A. V.; Попова-Кузнецова, Елена Алефтиновна; Тихоновский, Глеб Валерьевич; Попов, Антон Александрович; Деев, Сергей Михайлович; Климентов, Сергей Михайлович; Завестовская, Ирина Николаевна; Кабашин, Андрей Викторович© 2020 SPIE.Nanotechnology promises a major improvement of efficacy of nuclear medicine by targeted delivery of radioactive agents to tumors, but this approach still needs novel efficient nanoformulations to maximize diagnostic and therapeutic functions. Here, we present a two-step method of laser ablation and fragmentation in water to produce non-radioactive 152Sm-enriched samarium oxide nanoparticles (Sm NPs), which can be converted to radioactive form of 153Sm beta-emitters by neutron capture reaction. We found that laser ablation in deionized water leads to the formation of NPs having diverse morphology and broad size dispersion. To improve size characteristics of formed NPs, we applied additional femtosecond laser fragmentation step, which made possible a good control of mean NPs size under a drastic narrowing of size dispersion, and the spherical shape of formed NPs. Obtained colloidal solutions of Sm NPs were stable for several weeks after the synthesis. The formed NPs present a very promising object for nuclear nanomedicine.
