Cannabis detection with solid sensors and paper-based immunoassays by conjugating antibodies to nanocellulose

Publication year: 2023
Authors: Solin K. 1, Vuoriluoto M. 1, Khakalo A. 1, Tammelin T. 1
Published in: Carbohydrate Polymers, 2023, Vol. 304

Highly sensitive and specific diagnostics for cannabis usage are essential for rapid on-site screening for illicit drug usage. To improve the sensitivity of THC immunoassays, a proper immobilization of the sensing elements on the sensor substrate is critical. In this work, we demonstrated the utilization of EDC/NHS coupling chemistry with nanocellulose to obtain efficient anchor…

Non-catalytic proteins as promising detoxifiers in lignocellulosic biomass pretreatment: unveiling the mechanism for enhanced enzymatic hydrolysis

Publication year: 2023
Authors: Meysam Madadi a, Guojie Song a, Vijai Kumar Gupta b,c, Mortaza Aghbashloh d, Chihe Sun a, Fubao Sun *a, Meisam Tabatabaei *e,f
Published in: Green Chemistry, 2023, Vol. 25 (18), p. 7141-7156

Dilute acid (DA) pretreatment of biomass generates multiple inhibitory compounds within the pretreated hydrolysates. These compounds subsequently contribute to the formation of pseudo-lignin on the surface of the substrate, consequently impeding the efficiency of enzymatic digestibility. To detoxify the DA pretreated hydrolysates, post-incubation with non-catalytic proteins (amaranth protein, AP; soy protein, SP; bovine serum albumin,…

Alpha hemolysin of E. coli induces hemolysis of human erythrocytes independently of toxin interaction with membrane proteins

Publication year: 2024
Authors: Lucía Cané 1, Nicolás Andrés Saffioti 2, Sandrine Genetet 3, María Antonieta Daza Millone 4, Mariano A Ostuni 3, Pablo J Schwarzbaum 5, Isabelle Mouro-Chanteloup 3, Vanesa Herlax 6
Published in: Biochimie, 2024, Vol. 216, p. 3-13

Alpha hemolysin (HlyA) is a hemolytic and cytotoxic protein secreted by uropathogenic strains of E. coli. The role of glycophorins (GPs) as putative receptors for HlyA binding to red blood cells (RBCs) has been debated. Experiments using anti-GPA/GPB antibodies and a GPA-specific epitope nanobody to block HlyA-GP binding on hRBCs, showed no effect on hemolytic…

Green Solvent-Based Antifouling Polymer Brushes Demonstrate Excellent Hemocompatibility

Publication year: 2023
Authors: Englert J. 1,2, Palà M. 3, Witzdam L. 1,4,5, Rayatdoost F. 6, Grottke O. 6, Lligadas G. 3, Rodriguez-Emmenegger C. 1,5,7,8
Published in: Langmuir, 2023, Vol. 39(50), p. 18476-18485

Medical devices are crucial for patient care, yet even the best biomaterials lead to infections and unwanted activation of blood coagulation, potentially being life-threatening. While hydrophilic polymer brushes are the best coatings to mitigate these issues, their reliance on fossil raw materials underscores the urgency of bio-based alternatives. In this work, we introduce polymer brushes…

A stable physisorbed layer of packed capture antibodies for high-performance sensing applications

Publication year: 2023
Authors: Lucia Sarcina a,+, Cecilia Scandurra a,+, Cinzia Di Franco b, Mariapia Caputo c, Michele Catacchio c, Paolo Bollella a,d, Gaetano Scamarcio e,d, Eleonora Macchia c,d,f,*, Luisa Torsi d,f,*
Published in: Journal of Materials Chemistry C, 2023, Vol. 11(27), p. 9093–9106

Antibody physisorption at a solid interface is a very interesting phenomenon that has important effects on applications such as the development of novel biomaterials and the rational design and fabrication of high-performance biosensors. The strategy selected to immobilize biorecognition elements can determine the performance level of a device and one of the simplest approaches is…

Published in: ACS Omega, 2023, Vol.8, Issue 30, p. 27566-27575

Graphene oxide has been widely deployed in electrical sensors for monitoring physical, chemical, and biological processes. The presence of abundant oxygen functional groups makes it an ideal substrate for integrating biological functional units to assemblies. However, the introduction of this type of defects on the surface of graphene has a deleterious effect on its electrical…

Advanced therapies with combined approaches of cell and nanomedicine-based interventions are emerging. Corneal blindness with a severe form of limbal stem cell (LSC) deficiency is an example of defect with unmet clinical need. Towards cell-based therapy, advanced enabling technologies are needed for efficient intracellular delivery of biomolecules both for in vitro disease modeling and for…

Biophysical Analysis to Assess the Interaction of CRAC and CARC Motif Peptides of Alpha Hemolysin of Escherichia coli with Membranes

Publication year: 2023

Alpha hemolysin of Escherichia coli (HlyA) is a pore-forming protein, which is a prototype of the “Repeat in Toxins” (RTX) family. It was demonstrated that HlyA-cholesterol interaction facilitates the insertion of the toxin into membranes. Putative cholesterol-binding sites, called cholesterol recognition/amino acid consensus (CRAC), and CARC (analogous to CRAC but with the opposite orientation) were identified in the…
