Viscoelasticity, Lubricity, and Wear Prevention of Cross‐Linked Mucin Gels
Advanced Materials Interfaces, EarlyView.Physiologically, biolubrication by mucus reduces friction and protects tissues from tribological stress, with mucins playing a key role. This study compares mucin‐based gels with distinct crosslinking architectures to explore their effect on the lubrication and wear prevention abilities of reconstituted mucin gels.

The permeability of the gastric mucosa of dog
The Journal of Physiology, 1966 1. Tritiated water, [14C]urea, [14C]thiourea, [14C]sucrose and [59Fe]‐haemoglobin were used to study the permeability of a semi‐isolated piece of the great curvature of the canine stomach.2. The osmotic pressure of the solutions placed in contact with the secretory surface of the epithelium was changed by means of dextrose or urea.

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...
