摘要: This work reports on superparamagnetic hydrogel composites suitable for Two-Photon Polymerization (TPP) and their application the fabrication of helical swimming microrobots, also known as Artificial Bacterial Flagella (ABFs). Suitable compositions consisting multifunctional monomers were identified based percolation theory prepared accordingly. Hydrogel ABFs 28 µm in length 3 diameter fabricated actuated DI water. The investigated (polyethylene glycol (PEG)) is particular interest to biomedical MEMS community. PEG can absorb/release water-soluble drugs highly resistant protein adsorption. combination nanoparticles enables corkscrew propulsion ABFs, making them ideal candidates applications vivo vitro.
