We present a new approach which aims to translate freeform biofabrication into the surgical field, while staying true practical constraints of operating theatre. Herein we describe development handheld tool, dubbed 'biopen', enables deposition living cells and biomaterials in manual, direct-write fashion. A gelatin–methacrylamide/hyaluronic acid–methacrylate (GelMa/HAMa) hydrogel was printed UV crosslinked during process generate surgically sculpted 3D structures. Custom titanium nozzles...
Cellulose nanofibrils (CNFs) in the form of hydrogels stand out as a platform biomaterial bioink formulation for 3D printing because their low cytotoxicity and structural similarity to extracellular matrices. In present study, scaffolds were successfully printed with low-concentration inks formulated by 1 w/v % 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized CNF less than gelatin methacrylate (GelMA). Quartz crystal microbalance dissipation monitoring (QCM-D) measurements...
Abstract Extrusion printing of interdigitated electrodes for flexible microsupercapacitors (fMSCs) offers an attractive route to the fabrication devices where cost, scalability, and processability ink formulations are critical. In this work, highly concentrated, viscous, water‐dispersible inks developed based on graphene oxide (GO)/polyaniline (PANi) composite extrusion printing. The optimized GO/PANi‐based all‐solid‐state symmetric fMSCs obtained by microelectrodes can deliver outstanding...
We present for the first time approaches to 3D-printing of nanocellulose hydrogel scaffolds based on double crosslinking, by in situ Ca2+ crosslinking and post-printing chemical with 1,4-butanediol diglycidyl ether (BDDE). Scaffolds were successfully printed from 1% hydrogels, their mechanical strength being tunable range 3 8 kPa. Cell tests suggest that 3D-printed BDDE-crosslinked supported fibroblast cells' proliferation, which was improving increasing rigidity. These render a new member...
Photo-crosslinkable hydrogels, in particular gelatin methacryloyl (GelMa), are gaining increasing importance biofabrication and tissue engineering. While GelMa is often described as mechanically 'tunable', clear relationships linking the photocrosslinking conditions to reaction rates, resulting mechanical properties, have not been described. Meanwhile employed literature disparate, difficult compare. In this work, situ rheological measurements were used quantify relative rate of hydrogels...
Organic conducting polymers (OCPs) are currently the subject of intense research in area biomaterials and bioelectronics. Of OCPs, poly(3,4‐ethylenedioxythiophene) (PEDOT) has attracted significant interest, however there been little work on investigating incorporation biological compounds as dopant species polymer which aimed at enhancing biocompatibility biofunctionality material. Here, we incorporate dopants dextran sulphate, chondroitin alginate, into PEDOT investigate their influence a...
This paper proposes the use of a 3D extrusion printer to fabricate artificial magnetic cilium. The cilia are fabricated using polydimethylsiloxane (PDMS) doped with iron particles so that they remain slender and flexible. They can be driven by field closely mimic behaviour biological cilia. Doping polymers has already been done; however, best our knowledge, printing such active soft structures not. existing methods for manufacturing polymeric complex difficult fabrication micro-sized...
A water-based hybrid Ink comprised of GO/PANi hierarchical structure is facilely prepared with the stabilizer PEDOT:PSS by Gordon G. Wallace, Jun Chen, and co-workers in article number 1706592. This kind formulated suitable for extrusion printing to directly fabricate both symmetric asymmetric microsupercapacitors. The devices cannot only deliver outstanding areal volumetric capacitance, but also exhibit improved single-device performance.
The local delivery of Cu2+ from copper-doped bioactive glass (Cu-BaG) was combined with 3D printing polycaprolactone (PCL) scaffolds for its potent angiogenic effect in bone tissue engineering. PCL and Cu-BaG were, respectively, dissolved dispersed acetone to formulate a moderately homogeneous ink. PCL/Cu-BaG were fabricated via direct ink writing into cold ethanol bath. architecture the printed scaffolds, including strut diameter, spacing, porosity, investigated characterized. showed...
