Electrochemical sensors for real-time detection of several bioanalytes have been prepared by additive manufacturing, shaping non-conductive poly(lactic acid) (PLA) filaments, and applying a physical treatment to create excited species. The latter process, which consists the application power discharge 100 W during 2 min in chamber at low pressure O2, converts electrochemically inert PLA into an responsive material. electric caused oxidation surface as evidenced increment quantity oxygenated...
Abstract Integrated electrochemical sensors in which plasma‐treated poly(lactic acid) (PLA) single material acts as both selective coating layer and transductor (electrode) are prepared. Thus, three‐dimensional‐printed PLA specimens transformed into electroresponsive by applying a low‐pressure gas plasma treatment with three different gases: N 2 , O air (79% + 21% ). Although all treated samples able to electrochemically detect dopamine, the one derived from of exhibits best performance...
Isotactic polypropylene (i-PP) nonabsorbable surgical meshes are modified by incorporating a conducting polymer (CP) layer to detect the adhesion and growth of bacteria sensing oxidation nicotinamide adenine dinucleotide (NADH), metabolite produced respiration reactions such microorganisms, NAD+. A three-step process is used for incorporation: (1) treat pristine with low-pressure O2 plasma; (2) functionalize surface CP nanoparticles; (3) coat homogeneous electropolymerized using...
Flexible electrochemical sensors based on electroactive materials have emerged as powerful analytical tools for biomedical applications requiring bioanalytes detection. Within this context, 3D printing is a remarkable technology developing devices, due to no design constraints, waste minimization, and batch manufacturing with high reproducibility. However, the fabrication of printed electrodes still limited by in‐house conductive filaments, which requires mixture material melted...
The development of experimental procedures to transform conventional materials into new with unique properties has become a necessity in many fields, as for example catalysis, electronics, electrochemistry and biomedicine, among others. In recent years, the thermal stimulated polarization (TSP) treatment, which consists applying constant voltage at high temperature, been applied hydroxyapatite, Ca5(PO4)3OH (HAp), leading permanently polarized HAp (p-HAp). enhanced electrical p-HAp, are...
Virtually, all implantable medical devices are susceptible to infection. As the main healthcare issue concerning is elevated risk of infection, different strategies based on coating or functionalization biomedical with antiseptic agents antibiotics proposed. In this work, an alternative approach presented, which consists sensors capable detecting infection at very early stages through continuous monitoring bacteria metabolism. This approach, implemented in surgical sutures as a...
In the present study, a composite made of conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), and biodegradable hydrogel poly(aspartic acid) (PASP) were electrochemically interpenetrated with poly(hydroxymethyl-3,4-ethylenedioxythiophene) (PHMeDOT) to prepare new polymer network (IPN). Different cross-linker PEDOT MPs contents, as well different electropolymerization times, studied optimize structural electrochemical properties. The properties material, being electrically...
Surgical sutures are long-established medical devices that play an important role closing and healing damaged tissues organs postoperatively. However, current commercial not able to detect infections at the wound site, which quite frequent after surgery. In this work, we present mechanically stable smart for real-time monitoring of bacterial growth biofilm formation. For purpose, a conducting polymer named poly(3,4-ethylenedioxythiophene) (PEDOT), is bacteria metabolites, was implemented as...
The transition from insulator to electro-responsive has been successfully achieved by earlier studies for some inorganic materials applying external stimuli that modify their 3D and/or electronic structures. In the case of insulating polymers, this is frequently accomplished mixing them with other electroactive materials, even though a few physical treatments induce suitable chemical modifications have also reported. work, smart approach based on application an electro-thermal reorientation...
Polypropylene (PP), thermoplastic polyurethane (TPU), polyethylene terephthalate glycol (PETG) and polylactic acid (PLA) 3D printed specimens, which are intrinsically non-electroresponsive materials, have been converted into electroresponsive electrodes applying a low-pressure oxygen plasma treatment. After complete chemical, morphological electrochemical characterization, treated samples applied as integrated sensors for detecting dopamine serotonin by cyclic voltammetry chronoamperometry....
