    Poly(L-lactide)/nano-hydroxyapatite piezoelectric scaffolds for tissue engineering
    (2024) Zaszczyńska, Angelika; Gradys, Arkadiusz; Kołbuk, Dorota; Zabielski, Konrad; Szewczyk, Piotr; Stachewicz, Urszula; Sajkiewicz, Paweł
    The development of bone tissue engineering, a field with significant potential, requires a biomaterial with high bioactivity. The aim of this manuscript was to fabricate a nanofibrous poly(L-lactide) (PLLA) scaffold containing nano-hydroxyapatite (nHA) to investigate PLLA/nHA composites, particularly the effect of fiber arrangement and the addition of nHA on the piezoelectric phases and piezoelectricity of PLLA samples. In this study, we evaluated the effect of nHA particles on a PLLA-based electrospun scaffold with random and aligned fiber orientations. The addition of nHA increased the surface free energy of PLLA/nHA (42.9 mN/m) compared to PLLA (33.1 mN/m) in the case of aligned fibers. WAXS results indicated that at room temperature, all the fibers are in an amorphous state indicated by a lack of diffraction peaks and amorphous halo. DSC analysis showed that all samples located in the amorphous/disordered alpha’ phase crystallize intensively at temperatures just above the Tg and recrystallize on further heating, achieving significantly higher crystallinity for pure PLLA than for doped nHA, 70 % vs 40 %, respectively. Additionally, PLLA/nHA fibers show a lower heat capacity for PLLA in the amorphous state, indicating that nHA reduces the molecular mobility of PLLA. Moreover, piezoelectric constant d33 was found to increase with the addition of nHA and for the aligned orientation of the fibers. In vitro tests confirmed that the addition of nHA and the aligned orientation of nanofibers increased osteoblast proliferation.

    Coupling phosphonate oxidation and phosphate sequestration via Cu-La dual sites in La-based layered carbonate hydroxide

    Phosphonates are refractory pollutants that contribute to eutrophication through their transformation into bioavailable phosphate. Although Cu-based advanced oxidation processes (AOPs) can degrade phosphonates via high-valent Cu(III) species, the released phosphate strongly coordinates with Cu sites, causing catalyst poisoning and rapid performance decay. Herein, a Cu-containing La-based layered carbonate hydroxide (CuLa-LCH) is designed to couple phosphonate oxidation with in situ phosphate sequestration. The CuLa-LCH/peroxymonosulfate (PMS) system achieves complete degradation of aminotris(methylenephosphonic acid) within 30 min, while simultaneously enabling efficient phosphate sequestration via La sites. Mechanistic and theoretical results reveal that Cu sites activate PMS to form Cu(III) intermediates that initiate C-N bond cleavage and subsequent oxidation toward C-P bond cleavage and phosphate release, whereas spatially coupled La-containing sites preferentially sequester the liberated phosphate, preventing Cu deactivation. This dual-site functionality sustains catalytic activity by continuously removing phosphate from Cu centers. The CuLa-LCH/PMS system also shows good reusability, water-matrix tolerance and operational stability, while preliminary techno-economic analysis suggests its potential practical feasibility. This study provides a viable strategy for coupling phosphonate oxidation with phosphate sequestration for sustainable water treatment.

    Comparative Physicochemical Characterization of Electrospun PCL, PLLA, and PLCL Scaffolds and Cell Responses for Tissue Engineering Applications

    In tissue engineering, electrospun scaffolds are valued for their tunable features, which direct cell behavior. Within this study, we electrospun scaffolds from three common polyesters: polycaprolactone (PCL), poly(L-lactic acid) (PLLA), and poly(lactide-co-caprolactone) (PLCL), to identify differences in cell–material interactions. PLLA fibers had the largest average diameter (2.6 ± 0.2 µm), PLCL fiber diameter was intermediate (2.2 ± 0.5 µm), and PCL was the smallest (1.1 ± 0.6 µm). Additionally, X-ray photoelectron spectroscopy (XPS) revealed distinct surface chemistries that are correlated with streaming potential results at pH 7.4. PLCL fibers showed the most negative zeta potential (−36.4 ± 0.7 mV), followed by PLLA (−28.4 ± 0.8 mV) and PCL (−24.0 ± 0.5 mV). Mechanical testing indicates the highest strength for PLCL mats (5.6 ± 0.9 MPa), then PLLA (3.5 ± 0.3 MPa) and PCL (1.9 ± 0.1 MPa). Cell studies indicated lower initial adhesion of osteoblasts on PLCL (∼53%↓) and PLLA (∼73.6%↓) vs. PCL, likely reflecting PCL scaffold morphology; however, viability at 3 and 7 days was significantly higher on PLCL and PLLA. Microscopy studies confirmed greater filopodia and cell spreading on PLCL and PLLA. Overall, all three are suitable scaffold materials, with PLCL and PLLA supporting cytoskeleton organization and viability better.
