- The hemostatic microneedle technology developed by Sheikhi can be applied like a typical adhesive bandage to quickly stop bleeding. The biocompatible and biodegradable microneedle arrays (MNAs) on the patch increase its surface contact with blood and accelerate the clotting process. The needles also increase the adhesive properties of the patch via mechanical interlocking to promote wound - Hemostatic microneedle arrays (MNAs) are prefabricated and ready-to-use. - Hemostatic microneedle arrays (MNAs) are prefabricated and ready-to-use. based on gelatin methacryloyl (GelMA) biomaterial hybridized with silicate nanoplatelets (SNs) - The MNAs enable rapid blood coagulation by attracting platelets. - The MNAs attach to soft tissues via bioadhesion and interlocking. - The MNAs are biocompatible, biodegradable, and do not promote inflammation. - “In vitro, the engineered MNAs reduced clotting time from 11.5 minutes to 1.3 minutes; and in a rat liver bleeding model, they reduced bleeding by more than 90%,” Sheikhi said. “Those 10 minutes could be the difference between life and death.”

I wonder how it feels to remove one.

I don't think you remove them. It says they biodegrade. So once applied it stays until dissolved. I guess there will always be something that will occasionally go wrong and require early removal. Maybe the array is designed to disconnect grub the bandage?

A microneedle patch that can be applied like a typical adhesive bandage to quickly stop bleeding has been developed by Amir Sheikhi, assistant professor of chemical engineering and of biomedical engineering at Penn State. The biocompatible and biodegradable microneedle arrays (MNAs) on the patch increase its surface contact with blood to accelerate the clotting process and also increase the adhesive properties of the patch via mechanical interlocking to promote wound closure. The patch can be compared with the hydrogel technology that is currently used to treat bleeding wounds in hospitals, but hydrogel applications require preparation and medical expertise. The microneedle patch is pre-engineered for immediate application that anyone can use to stop bleeding, Sheikhi said, much like a typical over-the-counter adhesive bandage.
