Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Post‐Newtonian Smoothed Particle Hydrodynamics [PDF]

The Astrophysical Journal, 2001
We introduce an adaptation of the well-known tree+SPH numerical scheme to post-Newtonian (PN) hydrodynamics and gravity. Our code solves the (0 + 1 + 2.5)PN equations. These equations include Newtonian hydrodynamics and gravity (0PN), the first-order relativistic corrections to those (1PN), and the lowest order gravitational radiation terms (2.5PN). We

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Ultrasound‐Responsive Dual‐Prodrug Nanoassembly for “Fenestrae‐Restoration Strategy” in Liver Fibrosis Therapy

Advanced Materials, EarlyView.
ABSTRACT Liver fibrosis is a serious yet reversible intermediate stage in the progression of liver disease, which can ultimately advance to cirrhosis and hepatocellular carcinoma. Targeted and selective inhibition of activated hepatic stellate cells (aHSCs) has emerged as a promising therapeutic strategy for the treatment of liver fibrosis.

Hydrodynamics coalescence collision of three liquid drops in 3D with smoothed particle hydrodynamics

AIP Advances, 2012
The Smoothed Particle Hydrodynamics method (SPH) has been useful to model continuous fluid. This method is employed to obtain approximate numerical solutions of the equations in fluid dynamics by replacing the fluid with a set of particles.
