A Soft Microrobot for Single‐Cell Transport, Spheroid Assembly, and Dual‐Mode Drug Screening

open access: yesAdvanced Materials, EarlyView.
A soft, untethered hydrogel microrobot enables precise single‐cell delivery, self‐assembly into 3D spheroids, and real‐time thermal actuation. Driven by light‐induced convection and embedded with gold nanorods and temperature sensors, the microrobot guides cells, modulates local microenvironments, and supports drug testing.

Control of cell differentiation by mechanical stress

open access: yesJournal of Physical Fitness and Sports Medicine, 2013
Cells sense mechanical force and their physical environment to change their fate and behavior through mechanotransduction. The mechanotransduction is, by translating mechanical forces and deformations into biochemical intracellular signaling, changing ...

Poking Pluripotency: Nanoinjection Into Human iPSCs

open access: yesAdvanced Materials, EarlyView.
Nanoinjection into hiPSCs: silicon nanotubes effectively transfect human induced pluripotent stem cells (hiPSCs) with mRNA, enabled by a delayed extracellular matrix application and enhanced surface functionalization. Nanoinjection is demonstrated with several reporter mRNA, including co‐transfection of mCherry and GFP.

The murine catecholamine methyltransferase mTOMT is essential for mechanotransduction by cochlear hair cells

open access: yeseLife, 2017
Hair cells of the cochlea are mechanosensors for the perception of sound. Mutations in the LRTOMT gene, which encodes a protein with homology to the catecholamine methyltransferase COMT that is linked to schizophrenia, cause deafness.

Mechanobiology of bone remodeling and fracture healing in the aged organism

open access: yesInnovative Surgical Sciences, 2016
Bone can adapt to changing load demands by mechanically regulated bone remodeling. Osteocytes, osteoblasts, and mesenchymal stem cells are mechanosensitive and respond to mechanical signals through the activation of specific molecular signaling pathways.
