Abstract
The analytical performance of the microarray technique in screening the affinity and reactivity of molecules toward a specific target is highly affected by the coupling chemistry adopted to bind probes to the surface. However, the surface functionality limits the biomolecules that can be attached to the surface to a single type of molecule, thus forcing the execution of separate analyses to compare the performance of different species in recognizing their targets. Here, we introduce a new N,N-dimethylacrylamide-based polymeric coating, bearing simultaneously different functionalities (N-acryloyloxysuccinimide and azide groups) to allow an easy and straightforward method to co-immobilize proteins and oriented peptides on the same substrate. The bifunctional copolymer has been obtained by partial post-polymerization modification of the functional groups of a common precursor. This strategy represents a convenient method to reduce the number of analyses, therefore possible systematic or random errors, besides offering a drastic shortage in time, reagents, and costs.

The bi-functional copolymer has been obtained by partial post polymerization modification of the functional groups of a common precursor. A NMR characterization of the copolymer was conducted to quantify the percentage of NAS that has been transformed into azido groups. The polymer was used to coat surfaces onto which both native antibodies and alkyne modified peptides were immobilized, to perform the phenotype characterization of extracellular vesicles (EVs). This strategy represents a convenient method to reduce the number of analysis, thus possible systematic or random errors, besides offering a drastic shortage in time, reagents and costs.

A soft 3D polyacrylate hydrogel recapitulates the cartilage niche and allows growth-factor free tissue engineering of human articular cartilage. Acta Biomater 2019; 90:146-156. [PMID: 30910621 DOI: 10.1016/j.actbio.2019.03.040] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2018] [Revised: 03/19/2019] [Accepted: 03/20/2019] [Indexed: 11/30/2022]
Abstract
Cartilage degeneration or damage treatment is still a challenge, but, tissue engineering strategies, which combine cell therapy strategies, which combine cell therapy and scaffolds, and have emerged as a promising new approach. In this regard, polyurethanes and polyacrylates polymers have been shown to have clinical potential to treat osteochondral injuries. Here, we have used polymer microarrays technology to screen 380 different polyurethanes and polyacrylates polymers. The top polymers with potential to maintain chondrocyte viability were selected, with scale-up studies performed to evaluate their ability to support chondrocyte proliferation during long-term culture, while maintaining their characteristic phenotype. Among the selected polymers, poly (methylmethacrylate-co-methacrylic acid), showed the highest level of chondrogenic potential and was used to create a 3D hydrogel. Ultrastructural morphology, microstructure and mechanical testing of this novel hydrogel revealed robust characteristics to support chondrocyte growth. Furthermore, in vitro and in vivo biological assays demonstrated that chondrocytes cultured on the hydrogel had the capacity to produce extracellular matrix similar to hyaline cartilage, as shown by increased expression of collagen type II, aggrecan and Sox9, and the reduced expression of the fibrotic marker's collagen type I. In conclusion, hydrogels generated from poly (methylmethacrylate-co-methacrylic acid) created the appropriate niche for chondrocyte growth and phenotype maintenance and might be an optimal candidate for cartilage tissue-engineering applications. SIGNIFICANCE STATEMENT: Articular cartilage has limited self-repair ability due to its avascular nature, therefore tissue engineering strategies have emerged as a promising new approach. Synthetic polymers displaygreat potential and are widely used in the clinical setting. In our study, using the polymer microarray technique a novel type of synthetic polyacrylate was identified, that was converted into hydrogels for articular cartilage regeneration studies. The hydrogel based on poly (methylmethacrylate-co-methacrylic acid-co-PEG-diacrylate) had a controlable ultrastructural morphology, microstructure (porosity) and mechanical properties (stiffness) appropriate for cartilage engineering. Our hydrogel created the optimal niche for chondrocyte growth and phenotype maintenance for long-term culture, producing a hyaline-like cartilage extracellular matrix. We propose that this novel polyacrylate hydrogel could be an appropriate support to help in the treatment efficient cartilage regeneration.

Array of multifunctional polymers for localized immobilization of biomolecules on microarray substrates. Anal Chim Acta 2019; 1047:188-196.

Abstract
The performance of microarray assays results from the optimization of several parameters: in particular, the physical-chemical properties of the surface play a pivotal role in determining the robustness of the technology. Usually, microarray substrates are entirely modified with coatings able to bind, covalently or not, bioprobes. Here we present a new, fully automated approach for the immobilization of biomolecules, based on the deposition of pL amounts of water solutions of DMA based copolymers on an uncoated surface, followed by the deposition, on the same spot, of the probe. Starting from a common precursor, polymers with different characteristics and functionalities are obtained by post-polymerization modification and by combining different monomers during the synthesis. This strategy, allows to functionalize and tailor the surface properties of discrete areas of the same array with different chemistries, that coexist on a single substrate. As a consequence, probes with different functionalities are bound simultaneously to neutral, positively, negatively charged, hydrophobic, hydrophilic polymers, in micrometer-sized spots. The proposed polymer array, applicable to both DNA or protein, offers advantages in terms of time and costs reduction, since pretreatment and coating steps are totally avoided, and the requested polymer amount is extremely low. Moreover, it provides a strategy perfectly suitable for miniaturization applicable to integrated biosensors or Lab-on-a-chip devices.
