Pushing the Boundaries of Interfacial Sensitivity in Graphene FET Sensors: Polyelectrolyte Multilayers Strongly Increase the Debye Screening Length
(American Chemical Society, 2018-05)
Nanomaterial-based FET sensors represent an attractive platform for ultrasensitive, real-time, and label-free detection of chemical and biological species. Nevertheless, because their response is screened by mobile ions, ...
Capacitive electrolyte-insulator-semiconductor structures functionalised with a polyelectrolyte/enzyme multilayer: New strategy for enhanced field-effect biosensing
(WILEY-V C H VERLAG GMBH, 2010)
A novel strategy for enhanced field-effect biosensing using capacitive electrolyte-insulator-semiconductor (EIS) structures functionalised with pH-responsive weak polyelectrolyte/enzyme or dendrimer/enzyme multilayers is ...
Impact of thermal annealing on wettability and antifouling characteristics of alginate poly-l-lysine polyelectrolyte multilayer films
(Elsevier Science, 2016-09)
Polyelectrolyte multilayers (PEMs) of poly- l-lysine (PLL) and alginic acid sodium salt (Alg) are fabricated applying the layer by layer technique and annealed at a constant temperature; 37, 50 and 80 °C, for 72 h. Atomic ...
Surfactant presence in a multilayer polyelectrolyte-enzyme system improves its catalytic response
(Elsevier Science Inc, 2009-05)
Self-assembling of poly(allylamine) containing an osmium polypyridil complex (PAOs) alternatively with sodium dodecyl sulfate (SDS) and glucose oxidase (GOx) generates a ternary multilayer system, (PAOs/SDS/PAOs/GOx)n. The ...
Enhanced antiadhesive properties of chitosan/hyaluronic acid polyelectrolyte multilayers driven by thermal annealing: Low adherence for mammalian cells and selective decrease in adhesion for Gram-positive bacteria
(Elsevier Science, 2017-11)
The development of antifouling coatings with restricted cell and bacteria adherence is fundamental for many biomedical applications. A strategy for the fabrication of antifouling coatings based on the layer-by-layer assembly ...

(Elsevier Science Sa, 2010-11)
In situ polarization modulation infrared reflection absorption spectroscopy (PM IRRAS) has been used to study layer-by-layer self-assembled films made of a novel redox polymer bearing an osmium pentacyano pyridine complex ...
PM-IRRA Spectroelectrochemistry of Hexacyanoferrate Films in Layer-by-Layer Polyelectrolyte Multilayers
(Wiley-VCH, 2013-10)
In situ polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS) under potential control is used to study self-assembled layer-by-layer (LbL) poly(allylamine) (PAH) and poly(acrylic acid) (PAA) ...
Amine-appended polyaniline as a water dispersible electroactive polyelectrolyte and its integration into functional self-assembled multilayers
(Pergamon-Elsevier Science Ltd, 2016-08)
We present an effective and simple method for the synthesis of poly(3-aminobenzylamine) (PABA) using a chemical oxidation strategy in aqueous solution. The polymer was characterized by NMR, LDI-TOF mass spectrometry, ...
