Enhanced activity of horseradish peroxidase in Langmuir-Blodgett films of phospholipids
(ELSEVIER SCIENCE BV, 2008)
The immobilization of enzymes in nanostructured films has potential applications, e.g. in biosensing, for which the activity may not only be preserved, but also enhanced if optimized conditions are identified. Optimization ...
The role of the C-terminal region of pulchellin A-chain in the interaction with membrane model systems
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Pulchellin is a Ribosome Inactivating Protein containing an A-chain (PAC), whose toxic activity requires crossing the endoplasmic reticulum (ER) membrane. In this paper, we investigate the interaction between recombinant ...
Mimetic biosensors composed by layer-by-layer films of phospholipid, phthalocyanine and silver nanoparticles to polyphenol detection
(2016-10-05)
Highly selective and sensitive modified electrodes have been the focus of many studies in sensing applications. Gene or enzymatic biosensors are greatly effective in this context, but they are often fragile and expensive. ...

Carbendazim e modelos de biomembrana via filmes de Langmuir e Layer-by-Layer: mecanismos de interação e desenvolvimento de sensores
(Universidade Estadual Paulista (Unesp), 2016-02-25)
Nesta tese filmes de Langmuir foram empregados para estudar a interação entre lipídios e um fungicida denominado carbendazim (MBC) e espectroscopia de impedância e espalhamento Raman amplificado em superfície (SERS, do ...
Using phospholipid Langmuir and Langmuir-Blodgett films as matrix for urease immobilization
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
The immobilization of enzymes in organized two-dimensional matrices is a key requirement for many biotechnological applications. In this paper, we used the Langmuir-Blodgett (LB) technique to obtain controlled architectures ...
Sensor array made with nanostructured films to detect a phenothiazine compound
(Amer Scientific Publishers, 2008-09-01)
The detection of trace amounts of phenothiazines with fast, direct methods is important for medical applications and the pharmaceutical industry. In this paper we explore the concept of an electronic tongue to detect ...
Penicillin-binding proteins (PBPs) determine antibiotic action in Langmuir monolayers as nanoarchitectonics mimetic membranes of methicillin-resistant Staphylococcus aureus
(2022-06-01)
The membrane of methicillin-resistant Staphylococcus aureus (MRSA) contains penicillin-binding proteins (PBPs) in the phospholipidic bilayer, with the protein PBP2a being linked with the resistance mechanism. In this work ...
