Researchers at Texas A&M University developed a method to embed microscopic phosphorescent sensor particles into 3D-printed biocompatible materials to monitor cell health noninvasively. [^1]

Virginia Tech chemists John Matson and Josh Worch and their teams are developing extra-sticky adhesives that can be broken down into their original components once they are no longer needed. [^2]

Dr. Michael McShane, professor of biomedical engineering and department head at Texas A&M, explained that the new sensor particles allow light transmission through tissue to monitor internal conditions without physical penetration. [^3]

Dr. Waqas Saleem, a researcher at the Texas A&M University Department of Biomedical Engineering, stated that current technologies for monitoring cell health are limited, bulky, and invasive. [^4]

The sensor particles are phosphorescent and absorb light from an inexpensive red LED, emitting modified light that indicates oxygen levels which correlate to nutrient levels like glucose and lactate. [^5]

Clark Vu and Isaac Addo from the Matson lab developed a bottlebrush polymer adhesive that is four times stronger than the commercial adhesives used in duct tape. [^6]

Graduate researcher Regina Ham found that using lipoic acid to create extremely large, inherently tacky polymers produced an adhesive compound that outperforms heavy-duty duct tape in adhesion strength while remaining chemically recyclable. [^7]

Josh Worch, assistant professor of chemistry at Virginia Tech, stated that his lab developed a tape with adhesive and plastic backing layers that can be recycled together as a mono-material design. [^8]
