Special Issue Information

Dear Colleagues,

Advances in regenerative medicine have driven the development of functional biocompatible scaffolds that represent critical tools in tissue repair, drug delivery, and therapeutic interventions. These scaffolds provide a dynamic and supportive environment for cell proliferation, differentiation, and tissue remodeling. This Special Issue will showcase cutting-edge research and innovation in designing, fabricating, and applying nanostructured polymer scaffolds for diverse therapeutic needs.

This Special Issue will focus on nanostructured scaffold technologies for applications such as bone regeneration, neural repair, wound healing, and targeted drug delivery. Possible research topics include surface functionalization strategies, self-healing and injectable hydrogels, bioactive and biodegradable materials, and advanced manufacturing techniques such as 3D printing and electrospinning. Emphasis will be placed on translational research and the integration of scaffolds into clinical practice.

Near-Infrared and Sono-Enhanced Photodynamic Therapy of Prostate Cancer Cells Using Phyto-Second Harmonic Generation Nanoconjugates
by Efrat Hochma, Michael A. Firer and Refael Minnes
Polymers 2025, 17(13), 1831; https://doi.org/10.3390/polym17131831 - 30 Jun 2025
Abstract
This study investigates near‑infrared (NIR)-induced, Phyto-enhanced, second harmonic generation-mediated photodynamic therapy (Phyto-SHG-PDT) using barium titanate (BT)/rhein/polyethylene glycol 100 (PEG100) and BT/Yemenite “Etrog” leaf extract/PEG100 nanoconjugates. We compare continuous-wave (CW), multi-line Argon-ion laser illumination in the NIR range with high-peak-power femtosecond (fs) 800 nm [...] Read more.
This study investigates near‑infrared (NIR)-induced, Phyto-enhanced, second harmonic generation-mediated photodynamic therapy (Phyto-SHG-PDT) using barium titanate (BT)/rhein/polyethylene glycol 100 (PEG100) and BT/Yemenite “Etrog” leaf extract/PEG100 nanoconjugates. We compare continuous-wave (CW), multi-line Argon-ion laser illumination in the NIR range with high-peak-power femtosecond (fs) 800 nm pulses. Under CW NIR light, BT/rhein nanoconjugates reduced PC3 prostate cancer cell viability by 18% versus non‑irradiated controls (p < 0.05), while BT/extract nanoconjugates exhibited 15% dark toxicity. The observed SHG signal matched theoretical predictions and previous CW laser studies. Reactive Oxygen Species (ROS) scavenger 1,3-diphenyl-isobenzofuran (DPBF) showed reduced absorbance at 410 nm upon NIR illumination, indirectly supporting SHG emission at 400 nm from nanoconjugates. Under fs-pulsed laser exposure, pronounced two-photon absorption (TPA) and SHG effects were observed in both nanoconjugate types. Our results demonstrate the effectiveness of BT/rhein nanoconjugates under both laser conditions, while the BT/extract nanoconjugates benefited from high-power pulsed excitation. These results highlight the potential of BT-based Phyto-SHG-PDT nanoconjugates for NIR and blue light applications, leveraging nonlinear optical effects for advanced photochemical cancer therapies.

Our work describes the green synthesis of silver sulfide nanoparticles (Ag2S NPs) and their formulation into polycaprolactone fibers (PCL), aiming to improve the multifunctional biological performance of PCL membranes as scaffolds. For this purpose, an extract of rosemary (Salvia rosmarinus) was employed as a reducing agent for the Ag2S NPs, obtaining irregular NPs and clusters of 5–60 nm, with a characteristic SPR absorption at 369 nm. Ag2S was successfully incorporated into PCL fibers by electrospinning using heparin (HEP) as a stabilizer/biocompatibility agent, obtaining nanostructured fibers with a ca. 500–800 nm diameter. Different amounts of Ag2S NPs (0.05, 0.5, and 1 wt.%) enhanced the nanostructured membranes’ surface polarity and mechanical performance, with a controlled ion release after 6 days submerged in PBS solution, determined by cyclic voltammetry. As a result, PCL/HEP/Ag2S scaffolds exhibit high antibacterial performance (80–90%) at early stages of contact (3 h) against E. coli and S. aureus. Also, cytotoxicity analysis demonstrated that the nanostructured membranes are biocompatible and exhibit high fibroblast cell regeneration, which is optimal for their application as scaffolds. To validate the regenerative response of PCL/HEP/Ag2S scaffolds, controlled wounds were induced in Wistar rats, presenting a favorable healing response by contact with PCL/HEP/Ag2S 1%, compared with the untreated wound. Our results indicated that nanostructured scaffolds enable the development of novel nanomaterials with multifunctional biological performance. Full article
