A Portable Smart-Phone Readout Device for the Detection of Mercury Contamination Based on an Aptamer-Assay Nanosensor
The detection of environmental mercury (Hg) contamination requires complex and expensive instruments and professional technicians. We present a simple, sensitive, and portable Hg2+ detection system based on a smartphone and colorimetric aptamer nanosensor. A smartphone equipped with a light meter app was used to detect, record, and process signals from a smartphone-based microwell reader (MR S-...
متن کاملDetection and Spatial Mapping of Mercury Contamination in Water Samples Using a Smart-Phone
Detection of environmental contamination such as trace-level toxic heavy metal ions mostly relies on bulky and costly analytical instruments. However, a considerable global need exists for portable, rapid, specific, sensitive, and cost-effective detection techniques that can be used in resource-limited and field settings. Here we introduce a smart-phone-based hand-held platform that allows the ...
متن کاملMedically Relevant Assays with a Simple Smartphone and Tablet Based Fluorescence Detection System
Cell phones and smart phones can be reconfigured as biomedical sensor devices but this requires specialized add-ons. In this paper we present a simple cell phone-based portable bioassay platform, which can be used with fluorescent assays in solution. The system consists of a tablet, a polarizer, a smart phone (camera) and a box that provides dark readout conditions. The assay in a well plate is...
متن کاملPoint-of-care detection of Escherichia coli O157:H7 in water using AuNPs-based aptasensor
Objective(s): Access to safe drinking and irrigation water has always been one of the major human concerns worldwide. Thus, rapid, sensitive, and inexpensive approaches for pathogenic bacteria detection, such as Escherichia coli O157:H7 (EHEC) that can induce important infectious diseases, are highly on demand. Materials and Methods: In ...
متن کاملتشخیص آنتیژن اختصاصی پروستات با استفاده از بیوسنسور الکتروشیمیایی مبتنی بر آپتامر
Background and Objectives: Detection of the biomarkers is one of the effective methods for diagnosis and treatment of prostate cancer. Prostate specific antigen (PSA) is currently the best biomarker available for controlling and detecting this cancer. The purpose of the current study was to design an electrochemical aptamer-based biosensor (electrochemical aptasensor) to measure...
