Poly vinyl alcohol pva mw 9000 10 000

Poly(D, L-lactide-co-glycolide) (PLGA, acid terminated, lactide/glycolide 50:50, Mw 38,000–54,000 Da), Poly(vinyl alcohol) (PVA, Mw 9000–10,000) and Nile Red were purchased from Sigma-Aldrich Chemical Co. (St. Louis, MO, USA). BCA Protein Assay Kit (BCA), 1,1'-Dioctadecyl-3,3,3',3'-Tetramethylindotricarbocyanine Iodide (DIR), Hoechst 33,342, Gibco Dulbecco's modified Eagle medium (DMEM), fetal bovine serum (FBS), trypsin–EDTA free (0.25%), penicillin–streptomycin (PS) were purchased from Thermo Fisher Scientific, Inc. (Waltham, MA, USA). Doxorubicin hydrochloride (DOX) was purchased from LC Laboratories (Woburn, MA, USA). (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) was purchased from Tokyo Chemical Industry Co., Ltd (Portland, OR, USA). EDTA-free mini protease inhibitor tablet was supplied by Roche Applied Science (Indianapolis, IN, USA). D-luciferin potassium salt was purchased from PerkinElmer, Inc. (Waltham, MA, USA). All other chemical reagents and solvents used in this research were purchased from Sigma-Aldrich and used directly without further process unless specially noted.

A sisal yarn, with an average diameter of 2.6 ± 0.35 mm and a linear density of 3300 Tex, was provided by the Sonajute company. This was later extracted from a Moroccan agave plant. The sisal yarn consists of a set of monofilaments, which exhibited a non-uniform network of overlapped fibres and little connected micro-pore structures with a roughness surface. The average diameter of the monofilament was approximately 200.56 ± 31.64 μm. This set of sisal monofilaments was twisted to 80 twists/metre in order to improve the elasticity, stretchability, and strength of the resulting yarn.
Poly (vinyl alcohol) (PVA, Mw 9000–10,000, 78–82% hydrolysed) was purchased from Sigma–Aldrich. Poly (3,4-ethylenedioxythiophene): Poly (styrene sulfonate), also named PEDOT:PSS, was supplied by the Heraeus company. PEDOT:PSS is expected to contribute to the electro-conductive sheath of the sensor yarns thanks to its prominent electrical conductivity, excellent mechanical strength, and thermal properties, even though this sample is well known to have more sensitivity to moisture hydration.
