n Flexible Sweat Sensor
Based on Photonic
Cellulose Nanocrystal
Researchers have reported
a sustainable, insoluble,
and chiral photonic cellulose
nanocrystal patch for
calcium ion (Ca2+) sensing
in sweat.
The
researchers
developed
a simple and efficient method to fabricate insoluble CNCbased
hydrogels. They found that by utilizing intermolecular hydrogen
bond reconstruction, thermal dehydration enabled the
optimized CNC composite photonic film to form a stable hydrogel
network in an aqueous solution. Moreover, they indicated that
hydrogel could be reversibly switched between dry and wet states,
which was convenient for specific functionalization.
The introduction of functionalized molecules by adsorption
swelling in a liquid environment resulted in a hydrogel with
freeze resistance (-20 °C), strong adhesion, good biocompatibility,
and high sensitivity to Ca2+.
This work is expected to facilitate the application of sustainable
cellulose sensors to monitor other metabolites (i.e., glucose,
urea, and vitamins, etc.).

n Disc-on-a-Chip for
Studying Back Pain
Engineers have unveiled
what they call an intervertebral
disc-on-a-chip, a worldfirst
precision engineered
toolbox for research into
lower back pain, the leading
cause of disability worldwide.
The disc-on-a-chip is a high-resolution 3D printed microfluidic
device with three channels allowing the accurate simulation
of the different regions within a natural disc and
even the personalization of the model to an individual. It is
a physiologically and clinically relevant in vitro model to
provide an accurate, controlled environment for lower back
pain research.
The chip can be used to replicate the degeneration of a
healthy disc or alternatively be set up as a degenerated disc to
test the efficacy of new pharmaceuticals or cell therapy. It enables
performing cost- and time-effective lab experiments
with the potential to enhance the physiological relevance of
experimental data leading to successful clinical outcomes. It
also offers the opportunity to reduce the need for animal use
in the lab. (Image credit: University of Technology Sydney)
