This novel technology provides early warning of complications to improve wound care. The paper-like, battery-free PETAL sensor patch uses five colorimetric sensors to measure biomarkers in the wound within 15 mins. A proprietary AI algorithm quickly analyses the digital image of the sensor patch to determine wound healing status with an accuracy rate of 97%.

Immunotherapies that block checkpoint receptors like PD-1, proteins that limit the capacity of T cells to attack tumors, have become the choice for the treatment of numerous types of solid cancer. However, the introduction of PD-1-blocking agents can often result in T cells attacking healthy tissues in addition to cancer cells, causing severe, sometimes life-threatening, side effects that can blunt the benefits of immunotherapy. A new study reveals new insights into how PD-1 functions to maintain healthy tissues, findings that can help scientists predict, treat, or even prevent the side effects of PD-1 blocking immunotherapies.

But researchers have now developed a wound-healing ink that can actively encourage the body to heal by exposing the cut to immune-system vesicles. The ink can be spread into a cut of any shape using a 3D-printing pen, and in mice, the technology nearly completely repaired wounds in just 12 days.

The porous structure of the nanopaper means that it can conform and adhere to the skin well enough for effective signal transfer and allows moisture to pass through for breathability and comfort. It is hoped that the nanopaper can soon be used to acquire electrophysiological data, such as ECGs in the clinic.

It has also been reported that vesicles called exosomes produced by these CAFs play an important role in cancer progression. A research group investigated the effect of CAF-derived exosomes on the growth of malignant melanoma cells. They found that CAF-derived exosomes express CD9 and CD63 transmembrane proteins, and that the CD9-positive exosomes may inhibit the growth of malignant melanoma cells.

The new technique has the potential to overcome many of the delivery hurdles faced by other promising mRNA therapies. The researchers use EV-encapsulated mRNA to initiate and sustain collagen production for several months in the cells of photoaged skin in laboratory models. It is the first therapy to demonstrate this ability and represents a proof-of-concept for deploying the EV mRNA therapy.

Combining techniques in nanotechnology and optics, researchers produced tiny (nanometric) diamond particles so small that they are capable of penetrating skin to deliver these remedies. Next, they created a safe, laser-based optical method that quantifies nanodiamond penetration into the various layers of the skin and determines their location and concentration within body tissue in a non-invasive manner -- eliminating the need for a biopsy.
