V. Yu. Timoshenko,A. A. Kudryavtsev,Liubov A. Osminkina,A. S. Vorontsov,Yu. V. Ryabchikov,I. A. Belogorokhov,Dmitri Kovalev,Pavel K. Kashkarov +7 more
TL;DR: In this article, the quenching of the exciton photoluminescence of silicon nanocrystals has been shown to decrease the number of cancer mouse fibroblast cells when they come into contact with photoexcited silicon nanoparticles.
Journal ArticleDOI
Porous Silicon Nanoparticles as Efficient Sensitizers for Sonodynamic Therapy of Cancer
Liubov A. Osminkina,A. L. Nikolaev,A.P. Sviridov,N. V. Andronova,Konstantin Tamarov,M. B. Gongalsky,A. A. Kudryavtsev,H.M. Treshalina,V. Yu. Timoshenko +8 more
TL;DR: In this paper, the authors investigated the use of nanoparticles for ultrasound-assisted therapy of cancer cells in vitro and in vivo, and found that the nanoparticles were almost nontoxic up to the concentration of 0.1 µmg/mL and doses of 30 µg/kg, respectively.
Journal ArticleDOI
Laser-synthesized oxide-passivated bright Si quantum dots for bioimaging
M. B. Gongalsky,Liubov A. Osminkina,Liubov A. Osminkina,A. Pereira,A. A. Manankov,A. A. Fedorenko,Alexander N. Vasiliev,V. V. Solovyev,A. A. Kudryavtsev,Marc Sentis,Marc Sentis,Andrei V. Kabashin,V. Yu. Timoshenko,V. Yu. Timoshenko +13 more
TL;DR: In this paper, an ultrapure laser-synthesized Si-based quantum dot (QD) was proposed for bioimaging based on photoluminescence (PL) in the visible and near-infrared spectral regions.
Journal ArticleDOI
Nanoparticles prepared from porous silicon nanowires for bio-imaging and sonodynamic therapy
Liubov A. Osminkina,Vladimir Sivakov,Grigory A Mysov,Veronika A. Georgobiani,Ulyana А Natashina,Florian Talkenberg,V. V. Solovyev,A. A. Kudryavtsev,Victor Yu. Timoshenko +8 more
TL;DR: It has been found that SiNPs can act as efficient sensitizers of ultrasound-induced suppression of the viability of Hep-2 cancer cells and possibilities of their bio-imaging applications.
Journal ArticleDOI
Silicon nanocrystals as photo- and sono-sensitizers for biomedical applications
TL;DR: In this article, the effect of photo-excited silicon nanocrystals (nc-Si) on cancer cell proliferation was investigated and shown to suppress the proliferation of cancer cells under ultrasound irradiation.
