Tunable plasmonic tweezers based on graphene nano-taper for nano-bio-particles manipulation: numerical study.
Khorami AA, Barahimi B, Vatani S, Javanmard AS. Khorami AA, et al. Opt Express. 2023 Jun 19;31(13):21063-21077. doi: 10.1364/OE.485994. Opt Express. 2023. PMID: 37381215 Free article.
Our results show that the designed system with graphene nano-taper of L = 1200 nm length and W = 600 nm base size and THz source intensity of I = 2 mW/m(2), can trap polystyrene nanoparticles with diameters of D = 140, 73, and 54 nm, and with trap stiffnesses of k(y) = 9.9 …

Improved Flow Dynamics of Extracorporeal Membrane Oxygenation via Design Modification of Dual-Lumen Cannulas.
Azimi M, Liao S, Vatani A, Burrell A, Gregory SD. Azimi M, et al. ASAIO J. 2022 Nov 1;68(11):1358-1366. doi: 10.1097/MAT.0000000000001669. Epub 2022 Feb 15. ASAIO J. 2022. PMID: 35184087
Physiologic flow at the inferior vena cava (IVC) and superior vena cava (SVC) were applied along with a partial ECMO support of 2 L/min. The SST k-omega turbulent model was solved for 6.4 seconds. WSS, washout, stagnation volume, and recirculation were compared. ...

The effect of arterial cannula tip position on differential hypoxemia during venoarterial extracorporeal membrane oxygenation.
Wickramarachchi A, Burrell AJC, Stephens AF, Šeman M, Vatani A, Khamooshi M, Raman J, Bellomo R, Gregory SD. Wickramarachchi A, et al. Phys Eng Sci Med. 2023 Mar;46(1):119-129. doi: 10.1007/s13246-022-01203-6. Epub 2022 Dec 2. Phys Eng Sci Med. 2023. PMID: 36459331
Even during the highest level of support, P1 to P3 could only provide oxygenated VA-ECMO flow at 0.11 L/min to the brachiocephalic artery, compared with 0.5 L/min at P4. This study suggests that cerebral perfusion of VA ECMO flow can be increased by advancing the ar …

Development and Evaluation of a Novel Drainage Cannula for Venoarterial Extracorporeal Membrane Oxygenation.
Wickramarachchi A, Shirejini SZ, Vatani A, Rana A, Khamooshi M, Šeman M, Liao S, Jap E, Nguyen TH, Alt K, Burrell A, Pellegrino VA, Kaye DM, Hagemeyer CE, Gregory SD. Wickramarachchi A, et al. ASAIO J. 2025 Mar 1;71(3):235-244. doi: 10.1097/MAT.0000000000002360. Epub 2024 Dec 19. ASAIO J. 2025. PMID: 39698917
When tested in the ex vivo loop, the novel design resulted in lower instances (two vs . four) and volumes of clot in the cannula (360.5 254.8 vs . 1258.0 651.7 l) when compared to the Bio-Medicus cannula. Results from tests assessing hemolysis, platelet activation, and oth …

Apoptotic Impact of Heliox Cold Plasma on a Cervical Cell Line Using Gold Nanoparticle-Doped Graphene Oxide Nanosheets.
Vatani M, Hosseinzadeh S, Sari A, Ghomi Marzdashti H, Rahimpour A, Fattahi R. Vatani M, et al. Iran J Pharm Res. 2024 Nov 12;23(1):e150385. doi: 10.5812/ijpr-150385. eCollection 2024 Jan-Dec. Iran J Pharm Res. 2024. PMID: 40066116 Free PMC article.
The biocompatible concentrations of GO and GO/Au nanoparticles were found to be 30 g/100 L and 20 g/100 L, respectively, as determined by the MTT assay. Radical formation increased as incubation time was extended from 30 to 60 seconds. ...
