The purpose of this work was to develop a family of crosslinked poly(xylitol adipate salicylate)s with a wide range of tunable release properties for delivering pharmacologically active salicylic acid. The synthesis parameters and release conditions were varied to modulate polyester properties and to understand the mechanism of release. Varying release rates were obtained upon longer curing (35% in the noncured polymer to 10% in the cured polymer in 7 days). Differential salicylic acid loading led to the synthesis of polymers with variable cross-linking and the release could be tuned (100% release for the lowest loading to 30% in the highest loading). Controlled release was monitored by changing various factors, and the release profiles were dependent on the stoichiometric composition, pH, curing time, and presence of enzyme. The polymer released a combination of salicylic acid and disalicylic acid, and the released products were found to be nontoxic. Minimal hemolysis and platelet activation indicated good blood compatibility. These polymers qualify as bioactive and resorbable and can, therefore, find applications as immunomodulatory resorbable biomaterials with tunable release properties.

Designer Fe3O4@Ag Core-Shell Porous Nanospheres for Enhanced Electromagnetic Interference Shielding of Polymer Nanocomposites

Indranil Chakraborty, Suryasarathi Bose, Kaushik Chatterjee

Summary: With the increasing usage of electronic gadgets, Electromagnetic (EM) pollution has become a pressing concern. A lightweight and flexible shield is in huge demand to comply with modern electronics. In this study, designer core-shell porous nanospheres (PNSs) are synthesized, and their composites with multiwalled carbon nanotubes (MWCNTs) are developed in ethylene-vinyl acetate (EVA) with excellent EM interference (EMI) shielding ability. The as-prepared Fe3O4 PNSs are coated with Ag by electroless deposition to enhance their effectiveness.

Embedding Silk Fibroin-Alginate Hydrogel in a 3D-Printed Porous Poly(Lactic Acid) Bone Tissue Scaffold Augments Stem Cell Function

Monika Rajput, Sagar Nilawar, Kaushik Chatterjee

Summary: Porous PLA scaffolds were prepared by fused filament fabrication, and a silk fibroin-alginate (SF/Alg) blend hydrogel loaded with hMSCs was loaded into the scaffold's pores. The gel-loaded PLA scaffolds showed stability, significant enhancement of hMSC proliferation and viability, and higher osteogenic differentiation. This combination offers a promising route for enhancing the bioactivity of 3D-printed PLA scaffolds.

Summary: The future of burn wound treatment lies in developing bioactive dressings for faster and more effective healing and regeneration. Silk fibroin (SF) hydrogels have proven regenerative abilities and are being explored as a burn wound dressing. A white light-responsive photopolymerization technique was adapted for gelation via photooxidation of tyrosine. The SF gel-incorporated dressing (SFD) fabricated using this technique showed moisture balance ability, cytocompatibility, and scarless healing in an in vivo test.

Micro-mechanisms underlying enhanced fatigue life of additively manufactured 316L stainless steel with a gradient heterogeneous microstructure

Sumit Ghosh, Nitish Bibhanshu, Satyam Suwas, Kaushik Chatterjee

Summary: The fatigue life of additively manufactured 316L stainless steel can be significantly improved through surface mechanical attrition treatment (SMAT). SMAT induces surface nano-crystallization and increases the resistance to fatigue crack initiation and propagation. After SMAT, the crack initiation site moves from the surface to the sub-surface layer.

Cooperative stiffening of flexible high aspect ratio nanostructures impart mechanobactericidal activity to soft substrates

Anindo Roy, Deepak Patil, Prasad K. D. V. Yarlagadda, Kaushik Chatterjee

Summary: This study investigates the antibacterial and antibiofouling properties of bioinspired high aspect ratio nanostructures generated on poly(ethylene terephthalate) (PET) surfaces. The results show that these structures effectively neutralize Gram-negative bacterial contamination but are unable to inactivate Gram-positive cells. The clustering of the soft, flexible tall nanopillars enhances the stiffness of the structures, and external capillary forces improve the killing efficiency. Additionally, experimental and computational investigations demonstrate the durability of the nanostructured surfaces against daily life forces.
