Hobæk TC, Pranov HJ, Larsen NB. Immobilization of Active Antibodies at Polymer Melt Surfaces during Injection Molding. Polymers (Basel) 2022; 14:polym14204426. [PMID: 36298004 PMCID: PMC9606872 DOI: 10.3390/polym14204426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 10/17/2022] [Accepted: 10/18/2022] [Indexed: 11/24/2022] Open
Abstract
We demonstrate the transfer and immobilization of active antibodies from a low surface- energy mold surface to thermoplastic replica surfaces using injection molding, and we investigate the process at molecular scale. The transfer process is highly efficient, as verified by atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) of the mold and replica surfaces. AFM analysis reveals partial nanometer-scale embedding of the protein into the polymer matrix as a possible mechanism of permanent immobilization. Replicas with rabbit anti-mouse IgG immobilized as capture antibody at the hot polymer melt surface during injection molding show similar affinity for their antigen (mouse IgG) in sandwich enzyme-linked immunosorbent assay (ELISA) as capture antibodies deposited by passive adsorption onto a bare thermoplastic replica. The transferred antibodies retain their functionality after incubation in serum-containing cell medium for >1 week. A mold coating time of 10 min prior to injection molding is sufficient for producing highly sensitive ELISA assays, thus enabling the short processing cycle times required for mass production of single-use biodevices relying on active immobilized antibodies.

The Effect of Physiological Incubation on the Properties of Elastic Magnetic Composites for Soft Biomedical Sensors. SENSORS (BASEL, SWITZERLAND) 2021; 21:7122. [PMID: 34770427 PMCID: PMC8588498 DOI: 10.3390/s21217122] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 10/21/2021] [Accepted: 10/24/2021] [Indexed: 12/28/2022]
Abstract
Magnetic micro- and nanoparticles (MPs)-based composite materials are widely used in various applications in electronics, biotechnology, and medicine. This group of silicone composites have advantageous magnetic and mechanical properties as well as sufficient flexibility and biocompatibility. These composites can be applied in medicine for biological sensing, drug delivery, tissue engineering, and as remote-controlled microrobots operating in vivo. In this work, the properties of polydimethylsiloxane (PDMS)-based composites with different percentages (30 wt.%, 50 wt.%, 70 wt.%) of NdFeB microparticles as a filler were characterized. The novelty of the work was to determine the influence of the percentage of MP content and physiological conditioning on the properties of the PDMS-MP composites after in vitro incubation. An important essence of the work was a comprehensive study of the properties of materials important from the point of view of medical applications. Materials were tested before and after conditioning in 0.9 wt.% NaCl solution at a temperature of 37 °C. Several studies were carried out, including thermal, physicochemical, and rheological tests. The results show that with an increase of the incubation time, most of the measured thermal and physicochemical parameters decreased. The presence of the magnetic filler, especially at a concentration of 70 wt.%, has a positive effect on thermal stability and physicochemical and rheological properties. The performed tests provided important results, which can lead to further research for a broader application of magnetic composites in the biomedical field.

Abstract
Radioimmunoassay (RIA) is an extremely specific and a highly sensitive type of immunoassay, but the long incubation time and generation of radioactive wastes limit the use of RIA. To complement these disadvantages of RIA, we suggest an advanced type of RIA based on a lab-on-a-chip (LOC) platform: μ-RIA. We designed a microfluidic chip for RIA and optimized the procedures of μ-RIA analysis, including surface modification, immunoreaction time, and washing. Based on the optimized conditions, we conducted a radioimmunoassay on the μ-RIA platform using a commercial RIA kit. With the μ-RIA, 5 min are adequate for analysis. The amount of reagent consumption is significantly reduced compared with conventional RIA. The standard curve with R2 = 0.9951 shows that we can quantitatively evaluate the amount of antigen present in unknown samples. We show the applicability of μ-RIA for the analysis of biomolecules and the potential of μ-RIA to be a novel platform for high-throughput analysis.

Abstract
The present report describes the integration and application possibilities of a new microarray concept based on adhesive surface. The method was shown to enable the straightforward production of 384 and 1536-well plates modified with 100 and 25 spots per well, respectively. Such in-well densities were only possible thanks to the fabrication process which implies first the deposition of the microarray on a flat adhesive surface and then its assembly with bottomless 384 or 1536-well plates. The concept was also confronted to various applications such as oligonucleotide detection, localised cell culture onto spotted adhesion proteins and immobilisation of peptide or active antibodies for immunoassays. In the particular case of immunotesting, the study focused on liver diseases diagnosis and more particularly on the detection of either one liver cancer marker, the alpha-fetoprotein, or the detection of Hepatitis C Virus infection. In every cases, interesting performances were obtained directly in crude patient serum, proof of the robust and generic aspect of the platform.

Abstract
We are reporting here a new technology for the straightforward production of integrated microarrays. The approach is based on the use of adhesive supports enabling (i) the immobilization of biomolecules as microarrays (up to 2500 spots per cm(2)) and (ii) the easy assembly of these microarrays with complex 3D structures such as 96-well bottomless microplates or polymer and glass microfluidic networks. The analytical performances of the system were demonstrated for sandwich protein detection (C-reactive protein) and hybridization assays, both in classical 96-well microplate format and microfluidic environment.

Abstract
An innovative method for the production of microfluidic chips integrating protein spots is described. The technology, called "Print-n-Shrink", is based on the screen-printing of a microfluidic design (using a dielectric ink) onto Polyshrink polystyrene sheets. The initial print which has a minimum size of 15 microm (height) x 230 microm (width) is thermally treated (30 seconds, 163 degrees C) to shrink and generate features of 85 microm (height) x 100 microm (width). Concomitantly, proteins such as monoclonal antibodies or cellular adhesion proteins are spotted onto the Polyshrink sheets and shrunk together with the microfluidic design, creating a complete biochip integrating both complex microfluidic designs and protein spots for bioanalytical applications.
