Material science is recognized as a frontrunner in achieving a sustainable future, owing to its primary reliance upon petroleum-based chemical raw materials. Several efforts are made to implement common renewable feedstocks as an alternative to common fossil resources. For this purpose, additive manufacturing (AM) represents promising and effective know-how for the replacement of high energy- and resource-demanding processes with more environmentally friendly practices. This work presents a novel biobased ink for stereolithography, which has been formulated by mixing a photocurable poly(ester amide) (PEA) obtained from renewable resources with citrate and itaconate cross-linkers and appropriate photopolymerization initiators, terminators, and dyes. The mechanical features and the relative biocompatibility of 3D-printed objects have been carefully studied to evaluate the possible resin implementation in the field of the textile fashion industry.

Melting Behavior of Compression Molded Poly(ester amide) from 2,5-Furandicarboxylic Acid.

Polymers (Basel)

December 2024

Department of Civil, Chemical, Environmental and Materials Engineering, University of Bologna, Via Terracini 28, 40131 Bologna, Italy.

PEA 46 is a biobased polymer with promising properties for sustainable packaging applications, which can be obtained via polymerization of a furan 2,5-dicarboxylic acid (2,5-FDCA) derivative and a diol monomer containing internal amide bonds (46 amido diol). In the literature, PEA 46 showed a complex series of thermal transitions during DSC scans. For this reason, in this initial exploratory study PEA 46 was subjected to compression molding and the melting behavior of film samples was investigated with parallel DSC and WAXS analyses.

The main advantages of microneedles are precise drug delivery through human skin, minimal tissue damage and painlessness. We conducted structural analysis and skin puncture studies of hollow microneedles using ANSYS for three materials: Hafnium Dioxide (HfO), Polyglycolic acid (PGA) and Polylactic acid (PLA). Firstly, we selected three lengths, three tip diameters and three base diameters to conduct a L(3) orthogonal experiment.

Diabetic retinopathy (DR) and age-related macular degeneration (AMD) are the primary causes of vision impairment and blindness worldwide. The current treatment for these diseases is an intravitreal injection of anti-VEGF agents, which are costly and require frequent injections. Implants can be used to sustain the release of drugs and minimize side effects.

Article Synopsis
  • The study focuses on an innovative thermosensitive quadpolymer designed for injection to deliver anti-fibrotic drugs, specifically targeting uterine fibroids while potentially preserving fertility.
  • The quadpolymer functions as an injectable solution at room temperature and transforms into a stable gel at body temperature, allowing for sustained release of the drug pirfenidone.
  • Results showed that the pirfenidone-loaded quadpolymer effectively inhibited fibroid cell proliferation, indicating its potential as a localized treatment option for uterine fibroid therapy.

Biodegradable polyesters provide an attractive alternative to non-degradable plastics but often encounter a tradeoff between biodegradability and mechanical properties because esters are rotational and lack hydrogen bonds. Conversely, natural polyamides, i.e.
