Effect of acoustic radiation force on displacement of nanoparticles in collagen gels
Løvmo, Mia Kvåle; Yemane, Petros Tesfamichael; Bjørkøy, Astrid; Hansen, Rune; Cleveland, Robin O.; Angelsen, Bjørn Atle Johan; Davies, Catharina de Lange (Peer reviewed; Journal article, 2020)Penetration of nanoscale therapeutic agents into the extracellular matrix (ECM) of a tumor is a limiting factor for the sufficient delivery of drugs in tumors. Ultrasound (US) in combination with microbubbles causing ... -
Effect of Acoustic Radiation Force on the Distribution of Nanoparticles in Solid Tumors.
Afadzi, Mercy; Myhre, Ola Finneng; Yemane, Petros Tesfamichael; Bjørkøy, Astrid; Torp, Sverre Helge; van Wamel, Annemieke; Lelu, Sylvie; Angelsen, Bjørn Atle Johan; Davies, Catharina de Lange (Peer reviewed; Journal article, 2020)Acoustic radiation force (ARF) might improve the distribution of nanoparticles (NPs) in tumors. To study this, tumors growing subcutaneously in mice were exposed to focused ultrasound (FUS) either 15 min or 4 h after the ... -
The Effect of Sonication on Extravasation and Distribution of Nanoparticles and Dextrans in Tumor Tissue Imaged by Multiphoton Microscopy
Yemane, Petros Tesfamichael; Åslund, Andreas; Sæterbø, Kristin Grendstad; Bjørkøy, Astrid; Snipstad, Sofie; van Wamel, Annemieke; Berg, Sigrid; Mørch, Ýrr Asbjørg; Hansen, Rune; Angelsen, Bjørn Atle Johan; Davies, Catharina de Lange (Journal article; Peer reviewed, 2018)Ultrasound (US)and systemic administration of microbubbles (MBs)have been shown to improve the delivery of drugs and nanoparticles (NPs)to tumor tissue. A better understanding of the mechanisms is crucial for effective ... -
Ultrasound for the delivery of a nanocarrier across biological barriers in tumors: impact of cavitation and acoustic radiation force
Yemane, Petros Tesfamichael (Doctoral theses at NTNU;2020:56, Doctoral thesis, 2020)Ultrasound for the delivery of a nanocarrier across biological barriers in tumors: impact of cavitation and acoustic radiation force Although conventional chemotherapy is the still one of the most important treatment ...
