Abstract Novel polyurethane copolymers derived from 4,4′‐methylenediphenyl diisocyanate (MDI), 1,4‐butanediol (BD) and α,ω‐dihydroxy‐[poly(caprolactone)‐poly (dimethylsiloxane)‐poly(caprolactone)] (α,ω‐dihydroxy‐(PCL‐PDMS‐PCL); $ \overline M _{\rm{n}} = 6100 g mol −1 ) were synthesized by a two‐step polyaddition reaction in solution. In the synthesis of polyurethanes, PCL blocks served as compatibilizer between nonpolar PDMS polar comonomers, MDI BD. The thermoplastic polyurethanes (TPU)...
Properties and biocompatibility of a series thermoplastic poly(urethane-siloxane)s (TPUSs) based on α,ω-dihydroxy ethoxy propyl poly(dimethylsiloxane) (PDMS) for potential biomedical application were studied. Thin films TPUSs with different PDMS soft segment content characterized by 1H NMR, quantitative 13C Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), contact angle, water absorption...
Two series of polyurethane (PU) networks based on Boltorn ® hyperbranched polyester (HBP) and hydroxyethoxy propyl terminated poly(dimethylsiloxane) (EO-PDMS) or hydroxy (HP-PDMS), were synthesized.The effect the type soft PDMS segment properties PUs was investigated by Fourier transform infrared spectroscopy (FTIR), contact angle measurements, surface free energy determination, X-ray photoelectron (XPS), scanning electron microscopy (SEM), atomic force (AFM), dynamic mechanical thermal...
In this study we have performed a comprehensive genotoxicological survey along the 900 rkm of Sava River. total, 12 sites were chosen in compliance with goals GLOBAQUA project dealing effects multiple stressors on biodiversity and functioning aquatic ecosystems. The genotoxic potential was assessed using complex battery bioassays prokaryotes eukaryotes (freshwater fish). Battery comprised evaluation mutagenicity by SOS/umuC test Salmonella typhimurium TA1535/pSK1002. level DNA damage as...
Ruthenium complexes are attracting interest in cancer treatment due to their potent cytotoxic activity. However, as high toxicity may also affect healthy tissues, efficient and selective drug delivery systems tumour tissues needed. Our study focuses on the construction of such for Ru(II) upon exposure a weakly acidic environment tumours. As nanocarriers, mesoporous silica nanoparticles (MSN) utilized, whose surface is functionalized with two types ligands, (2-thienylmethyl)hydrazine...
Novel ferrite/polyurethane nanocomposites were synthesized using the in situ polymerization method after addition of different spinel nanoferrite particles (copper, zinc, and copper–zinc) examined as potential coatings for medical devices implants vascular tissue engineering. The influence type on structure functional characteristics polyurethane composites was investigated by FTIR, SWAXS, AFM, TGA, DSC, nanoindentation, swelling behavior, water contact angle, absorption measurements....
Flexible, wearable biomedical sensors based on laser-induced graphene (LIG) have garnered significant attention due to a straightforward fabrication process and exceptional electrical mechanical properties. However, most relevant studies rely commercial polyimide precursors, which suffer from inadequate biocompatibility weak adhesion between the precursor material LIG layer. To address these challenges, we synthesized cross-linked polyurethanes (PUs) with good used them as substrates for...
