Direct ink writing via single or multihead extrusion is used to synthesize layer-by-layer (LbL) meshes comprising renewable polysaccharides. The best mechanical performance (683 ± 63 MPa modulus and 2.5 ± 0.4 MPa tensile strength) is obse...
End-Functionalized Poly(vinylpyrrolidone) for Ligand Display in Lateral Flow Device Test Lines [0.03%]
用于横向流动装置测试线配体展示的端基官能化聚乙烯吡咯烷酮
