Magnetic bead-based electrochemical aptasensor doped with multi-wall carbon nanotubes for the detection of ampicillin in milk

open access: yesInternational Journal of Electrochemical Science, 2020
Given the ubiquitous presence of antibiotic residues in foodstuff, establishing an efficient method to determine antibiotic residuals is extremely urgent to ensure food safety. This work reports a magnetic bead-based electrochemical aptasensor doped with

Eco-Friendly Fluorescent ELISA Based on Bifunctional Phage for Ultrasensitive Detection of Ochratoxin A in Corn

open access: yesFoods, 2021
Conventional enzyme-linked immunosorbent assay (ELISA) is commonly used for Ochratoxin A (OTA) screening, but it is limited by low sensitivity and harmful competing antigens of enzyme-OTA conjugates.

Reconfiguration of Multiphase Coacervate Droplets Into Self‐Regulated Nested Artificial Cells

open access: yesAngewandte Chemie, EarlyView.
Living cells advance functionality through spatiotemporal sub‐compartmentalization and internal organization. Herein, we develop a self‐regulated artificial cell by transforming a membrane‐less multiphase coacervate droplet (MCD) into a membranized, structurally reinforced nested coacervate vesicle (NCV).

Role of YAP and TAZ in pancreatic ductal adenocarcinoma and in stellate cells associated with cancer and chronic pancreatitis. [PDF]

open access: yes, 2015
Pancreatic ductal adenocarcinoma (PDAC) is characterized by a fibrotic and inflammatory microenvironment that is formed primarily by activated, myofibroblast-like, stellate cells.

Conversion of cytochrome c into a peroxidase: inhibitory mechanisms and implication for neurodegenerative diseases. [PDF]

open access: yes, 2012
A further function of cytochrome c (cyt c), beyond respiration, is realized outside mitochondria in the apoptotic program. In the early events of apoptosis, the interaction of cyt c with a mitochondrion-specific phospholipid, cardiolipin (CL), brings ...

Integrated immunoassay-based broad detection of multi-class mycotoxins

open access: yesFood and Agricultural Immunology, 2018
Europium (Eu3+) and horse radish peroxidase (HRP) are highly promising biosensors due to its excellent physical and chemical properties. The two biosensors are widely applied in time-resolved fluoroimmunoassay (TRFIA) and chemiluminescence enzyme-linked ...

Preparation of the luciferase-labeled antibody for improving the detection sensitivity of viral antigen

open access: yesVirology Journal, 2022
Background Viral antigen detection test is the most common method used to detect viruses in the field rapidly. However, due to the low sensitivity, it can only be used as an auxiliary diagnosis method for virus infection. Improving sensitivity is crucial

Obtention of plant peroxidase and its potential for the decolorization of the reactive dye Remazol Turquoise G 133% [PDF]

open access: yes, 2012
Peroxidases can be used in the decolorization process. There is a growing interest for new sources of this enzyme and for obtaining economically viable processes. In this work, a low-cost vegetable peroxidase extraction process is proposed; the resulting

Localization of brain stem motoneurons innervating the laryngeal muscles in the rufous horseshoe bat,rhinolophus rouxi [PDF]

open access: yes, 1981
The motoneurons innervating the laryngeal muscles were localized in the rufous horseshoe bat,Rhinolophus rouxi, using the HRP method. HRP was applied to the cricothyroid muscle and to the cut end of the recurrent laryngeal nerve. Labeled motoneurons were
