Abstract
A material based on cellulose coated with polyaniline/poly (2-acrylamido-2-methyl-1-propanesulfonic acid) (Cell/PANI-PAMPSA) was synthesized in a simple way starting from cellulose fibres, aniline and using PAMPSA as dopant. The morphology, mechanical properties, thermal stability, and electrical conductivity were investigated by means of several complementary techniques. The obtained results highlight the excellent features of the Cell/PANI-PAMPSA composite with respect to the Cell/PANI one. Based on the promising performance of this material, novel device functions and wearable applications have been tested. We focused on its possible single use as: i) humidity sensors and ii) disposable biomedical sensors to provide immediate diagnostic services as close to the patient as possible for heart rate or respiration activity monitoring. To our knowledge, this is the first time that Cell/PANI-PAMPSA system has been used for such applications.

Abstract
![]()
Biomaterials capable
of precisely controlling the delivery of agrochemicals/biologics/drugs/fragrances
have significant markets in the agriscience/healthcare industries.
Here, we report the development of degradable electroactive polymers
and their application for the controlled delivery of a clinically
relevant drug (the anti-inflammatory dexamethasone phosphate, DMP).
Electroactive copolymers composed of blocks of polycaprolactone (PCL)
and naturally occurring electroactive pyrrole oligomers (e.g., bilirubin,
biliverdin, and hemin) were prepared and solution-processed to produce
films (optionally doped with DMP). A combination of in silico/in vitro/in
vivo studies demonstrated the cytocompatibility of the polymers. The
release of DMP in response to the application of an electrical stimulus
was observed to be enhanced by ca. 10–30% relative to the passive
release from nonstimulated samples in vitro. Such stimuli-responsive
biomaterials have the potential for integration devices capable of
delivering a variety of molecules for technical/medical applications.

Int J Biol Macromol 2021; 173:109-117.

Abstract
Although polyaniline (PANI) is a widely investigated conductive polymer for biological applications, studies addressing the biocompatibility of colloidal PANI dispersions are scarcely found in the literature of the area. Therefore, PANI nanoparticles stabilized by the natural polysaccharide gum Arabic (GA) were screened for their biocompatibility. The GA successfully stabilized the colloidal PANI-GA dispersions when exposed to a protein-rich medium, showing compatibility with the biological environment. The results obtained from a series of in vitro assays showed that, after up to 48 h of exposure to a range of PANI-GA concentrations (1-50 μg/mL), both mouse BALB/3T3 fibroblasts and RAW 264.7 macrophages showed no evidence of change in cellular proliferation, viability and metabolic activity. An increase in macrophage granularity poses as evidence of phagocytic uptake of PANI-GA, without resulting activation of this cell type. Additionally, the PANI-GA nanoparticles modulated the cell morphology changes induced on fibroblasts by GA in a concentration-dependent manner. Thus, this unprecedented biocompatibility study of PANI nanoparticles stabilized by a plant gum exudate polysaccharide showed promising results. This simple biomaterial might be further developed into colloidal formulations for biological and biomedical applications, taking advantage of its versatility, biocompatibility, and conductive properties.

Laser Processed Antimicrobial Nanocomposite Based on Polyaniline Grafted Lignin Loaded with Gentamicin-Functionalized Magnetite. Polymers (Basel) 2019; 11:polym11020283.

Abstract
Composite thin coatings of conductive polymer (polyaniline grafted lignin, PANI-LIG) embedded with aminoglycoside Gentamicin sulfate (GS) or magnetite nanoparticles loaded with GS (Fe₃O₄@GS) were deposited by the matrix-assisted pulsed laser evaporation (MAPLE) technique. The aim was to obtain such nanostructured coatings for titanium-based biomedical surfaces, which would induce multi-functional properties to implantable devices, such as the controlled release of the therapeutically active substance under the action of a magnetic and/or electric field. Thus, the unaltered laser transfer of the initial biomaterials was reported, and the deposited thin coatings exhibited an appropriate nanostructured surface, suitable for bone-related applications. The laser processing of PANI-LIG materials had a meaningful impact on the composites' wettability, since the contact angle values corresponding to the composite laser processed materials decreased in comparison with pristine conductive polymer coatings, indicating more hydrophilic surfaces. The corrosion resistant structures exhibited significant antimicrobial activity against Escherichia coli, Staphylococcus aureus, and Candida albicans strains. In vitro cytotoxicity studies demonstrated that the PANI-LIG-modified titanium substrates can allow growth of bone-like cells. These results encourage further assessment of this type of biomaterial for their application in controlled drug release at implantation sites by external activation.

Abstract
Malignant transformation is associated with enhancement of cell plasticity, which allows cancer cells to survive under different conditions by adapting to their microenvironment during growth and metastatic spread. Much effort has been devoted to understanding the molecular mechanisms of these processes. Although the importance of the extracellular matrix and of surface properties in these mechanisms is evident, the direct impact of distinct physical and chemical surfaces characteristics on cell fate remains unclear. Here, we have addressed this question using HT1080 fibrosarcoma cells as a model. To examine the relationship between surface topography, chemistry, and cell behavior, hydrophobic poly(butyl methacrylate-co-ethylene dimethacrylate) (BMA-EDMA) and hydrophilic poly(2-hydroxyethyl methacrylate-co-ethylene dimethacrylate) (HEMA-EDMA) surfaces with three different topographies (microporous, nanoporous, and nonporous) were generated. These surfaces were then modified by photoinitiated grafting of three different methacrylate monomers to create surface chemistry gradients of either negatively (AMPS) or positively (META) charged or zwitterionic (MDSA) functionalities. Our results show that AMPS promotes cell spreading, but that META abolishes cell growth. META and MDSA grafted on microporous BMA-EDMA produced superhydrophilic surfaces with high globularity and elasticity, which modified the cell phenotype by inhibiting cell spreading, followed by loss of mesenchymal characteristics and a reduction in protein levels of the mesenchymal markers N-cadherin, beta-catenin, p120 catenin, and also of the adaptor proteins vinculin and paxillin that are associated with adhesion and cancer cell invasion. The effect was strengthened along the gradient, suggesting that the density of the functional groups plays a role in this process. On the nanoporous surface, only MDSA grafting resulted in a significant increase in cell number, a reduction in N-cadherin expression, increased beta-catenin and p120 catenin levels, as well as the appearance of the epithelial marker E-cadherin. This indicates that the cancer cells have a high plasticity that is triggered by the collaborative effect of physical and chemical surface properties.

Abstract
Polyaniline shows great potential and promises wide application in the biomedical field thanks to its intrinsic conductivity and material properties, which closely resemble natural tissues. Surface properties are crucial, as these predetermine any interaction with biological fluids, proteins and cells. An advantage of polyaniline is the simple modification of its surface, e.g., by using various dopant acids. An investigation was made into the adhesion, proliferation and migration of mouse embryonic fibroblasts on pristine polyaniline films and films doped with sulfamic and phosphotungstic acids. In addition, polyaniline films supplemented with poly (2-acrylamido-2-methyl-1-propanesulfonic) acid at various ratios were tested. Results showed that the NIH/3T3 cell line was able to adhere, proliferate and migrate on the pristine polyaniline films as well as those films doped with sulfamic and phosphotungstic acids; thus, utilization of said forms in biomedicine appears promising. Nevertheless, incorporating poly (2-acrylamido-2-methyl-1-propanesulfonic) acid altered the surface properties of the polyaniline films and significantly affected cell behavior. In order to reveal the crucial factor influencing the surface/cell interaction, cell behavior is discussed in the context of the surface energy of individual samples. It was clearly demonstrated that the lesser the difference between the surface energy of the sample and cell, the more cyto-compatible the surface is.
