Lee H, Dey M, Karunakaran K, Picu C, Chasiotis I
Soft Matter . 2025 Feb; 21(10):1841-1848. PMID: 39905947
An integrated experimental-computational methodology was developed to study the mechanical behavior of random polymer nanofiber networks with controlled network structural parameters. Random nanofiber networks, comprised of continuous polyethylene oxide (PEO)...

Yang F, Das D, Chasiotis I
Appl Phys Lett . 2022 Mar; 120(11):114101. PMID: 35355883
The nonlinear mechanical behavior of individual nanoscale collagen fibrils is governed by molecular stretching and sliding that result in a viscous response, which is still not fully understood. Toward this...

Yang F, Das D, Karunakaran K, Genin G, Thomopoulos S, Chasiotis I
Acta Biomater . 2022 Mar; 163:63-77. PMID: 35259515
The viscoelastic mechanical behavior of collagenous tissues has been studied extensively at the macroscale, yet a thorough quantitative understanding of the time-dependent mechanics of the basic building blocks of tissues,...

Yang F, Das D, Chasiotis I
Opt Lasers Eng . 2022 Jan; 150. PMID: 35027783
Nanoscale macromolecular biological structures exhibit time-dependent behavior, yet a quantitative understanding of their time-dependent mechanical behavior remains elusive, largely due to experimental challenges in attaining sufficient spatial and temporal resolution...

Antartis D, Wang H, Tang C, Chew H, Dillon S, Chasiotis I
ACS Appl Mater Interfaces . 2019 Mar; 11(12):11715-11721. PMID: 30860348
We report on the chemical lithiation of long microscale helices composed of densely packed amorphous silicon (aSi) nanofibrils, fabricated by glancing angle deposition (GLAD) through e-beam evaporation. In situ electron...

Liu J, Das D, Yang F, Schwartz A, Genin G, Thomopoulos S, et al.
Acta Biomater . 2018 Sep; 80:217-227. PMID: 30240954
As the fundamental structural protein in mammals, collagen transmits cyclic forces that are necessary for the mechanical function of tissues, such as bone and tendon. Although the tissue-level mechanical behavior...

Kolluru P, Lipner J, Liu W, Xia Y, Thomopoulos S, Genin G, et al.
Acta Biomater . 2013 Aug; 9(12):9442-50. PMID: 23933048
Engineering complex tissues such as the tendon-to-bone insertion sites require a strong and tough biomimetic material system that incorporates both mineralized and unmineralized tissues with different strengths and stiffnesses. However,...

Naraghi M, Chasiotis I, Kahn H, Wen Y, Dzenis Y
Rev Sci Instrum . 2007 Sep; 78(8):085108. PMID: 17764356
A novel method to perform nanoscale mechanical characterization of highly deformable nanofibers has been developed. A microelectromechanical system (MEMS) test platform with an on-chip leaf-spring load cell that was tuned...
