Nucleic-acid hybridization assays based on the use of different inorganic-colloid (quantum dots) nanocrystal tracers for simultaneous electrochemical measurements multiple DNA targets are described. Three encoding nanoparticles (zinc sulfide, cadmium and lead sulfide) used to differentiate signals three in connection stripping-voltammetric heavy metal dissolution products. These products yield well-defined resolved stripping peaks at −1.12 V (Zn), −0.68 (Cd), −0.53 (Pb) mercury-coated...
We demonstrate the use of artificial nanomachines for effective interaction, capture, transport, and removal oil droplets. The simple nanomachine-enabled collection method is based on modifying microtube engines with a superhydrophobic layer able to adsorb by means its strong adhesion long chain self-assembled monolayers (SAMs) alkanethiols created rough gold outer surface device. resultant SAM-coated Au/Ni/PEDOT/Pt microsubmarine displays continuous interaction large droplets capable...
In this work, we developed an optical enzyme-linked immunosorbent assay (ELISA) immunoassay for the analysis of CA15-3 antigen, important biomarker present in blood samples and useful follow-up medical treatment breast cancer. Gold nanoparticles (AuNPs) were used as carriers signaling antibody anti-CA15-3−HRP (horseradish peroxidase) order to achieve amplification signal. range between 0 60 U/mL, adopting AuNPs enhancer resulted higher sensitivity shorter time when compared classical ELISA...
Because of its multifunctional character, nanocellulose (NC) is one the most interesting nature-based nanomaterials and attracting attention in a myriad fields such as biomaterials, engineering, biomedicine, opto/electronic devices, nanocomposites, textiles, cosmetics food products. Moreover, NC offers plethora outstanding properties, including inherent renewability, biodegradability, commercial availability, flexibility, printability, low density, high porosity, optical transparency well...
A novel double-codified nanolabel (DC-AuNP) based on gold nanoparticle (AuNP) modified with anti-human IgG peroxidase (HRP)-conjugated antibody is reported. It represents a simple assay that allows enhanced spectrophotometric and electrochemical detection of antigen human as model protein. The method takes advantage two properties the DC-AuNP label: first, HRP label activity toward OPD chromogen can be related to analyte concentration measured spectrophotometrically; second, intrinsic labels...
Recent years have faced stimulating developments in the functionalization of electrode surfaces with biological materials, notably due to significant input nanosciences and nanotechnology. In this review (over 450 references), we are discussing interest both nano-objects (metal nanoparticles quantum dots, carbon nanotubes graphene) nano-engineered and/or nanostructured materials (template-based advanced organic polymers) for rational design bio-functionalized electrodes related (bio)sensing...
New template-based self-propelled gold/nickel/polyaniline/platinum (Au/Ni/PANI/Pt) microtubular engines, functionalized with the Concanavalin A (ConA) lectin bioreceptor, are shown to be extremely useful for rapid, real-time isolation of Escherichia coli (E. coli) bacteria from fuel-enhanced environmental, food, and clinical samples. These multifunctional microtube engines combine selective capture E. uptake polymeric drug-carrier particles provide an attractive motion-based theranostics...
