Polydiacetylene-coated polyvinylidene fluoride strip aptasensor for colorimetric detection of zinc(II)
We report a new polydiacetylene (PDA) sensor strip for simple visual detection of zinc ions in aqueous solution. The specificity of this sensor comes from Zn2+ DNA aptamer probes conjugated onto PDA. Effects of aptamer length and structure on the sensitivity of PDA's color transition were first investigated. PDA conjugated with the optimal aptamer sequence was then coated onto a strip of polyvi...
متن کاملLabel-Free Colorimetric Detection of Influenza Antigen Based on an Antibody-Polydiacetylene Conjugate and Its Coated Polyvinylidene Difluoride Membrane
This study presents an antibody-conjugated polydiacetylene (PDA) and its coated polyvinylidene difluoride (PVDF) membrane. The M149 antibody was hybridized to nano-vesicles consisting of pentacosa-10,12-diynoic acid (PCDA) and dimyristoylphosphatidylcholine (DMPC). After photo-polymerization at 254 nm, the effects on the PDA by antigenic injection were investigated with UV-vis spectroscopy, flu...
متن کاملColorimetric Aptasensor Using Unmodified Gold Nanoparticles for Homogeneous Multiplex Detection
Colorimetric aptasensors using unmodified gold nanoparticles (AuNPs) have attracted much attention because of their low cost, simplicity, and practicality, and they have been developed for various targets in the past several years. However, previous research has focused on developing single-target assays. Here, we report the development of a homogeneous multiplex aptasensor by using more than o...
متن کاملPolyvinylidene fluoride sensor-based method for unconstrained snoring detection.
We established and tested a snoring detection method using a polyvinylidene fluoride (PVDF) sensor for accurate, fast, and motion-artifact-robust monitoring of snoring events during sleep. Twenty patients with obstructive sleep apnea participated in this study. The PVDF sensor was located between a mattress cover and mattress, and the patients' snoring signals were unconstrainedly measured with...
متن کاملPolyvinylidene Fluoride-coated Polypropylene Mesh for Intraperitoneal Onlay Mesh (IPOM) Repair of Ventral and Incisional Herniae
Background: Dynamesh is a Polyvinylidene fluoride-coated polypropylene mesh. Its main use is for ventral hernia repairs as an on-lay mesh. The mesh was designed to have similar elasticity to the abdominal wall. It is reported to have good anti-adhesive properties while the large pores ensure rapid integration into the abdominal wall. A small series last year reported a high rate of complication...
