Living Materials Approach for In Situ Bio-Polymers Production Using Bacillus Paralicheniformis in Microneedles. [PDF]
Adv Healthc MaterDissolvable microneedle (MN) device containing Bacillus paralicheniformis. The polymeric matrix encapsulates and protects the bacteria, preserving their viability while enabling in situ production and release of γ‐polyglutamic acid. The bacteria are delivered into the skin via 500 µm‐long microneedles, and remain detectable on the skin 24 h post ...
