چکیده

Lateral flow immunoassays (LFIA) are ideal biosensors to detect proteins, but their lack of sensitivity hinders their extensive use. We report a strategy that yields up to an 8-fold improvement in the sensitivity of a gold nanoparticles-based LFIA by changing the sizes of the pads. Theoretical flow simulations of the developed LFIA architectures are in accordance with the experimental results.

Platinum Nanocatalyst Amplification: Redefining the Gold Standard for Lateral Flow Immunoassays with Ultrabroad Dynamic Range

Paper-based lateral flow immunoassays (LFIAs) are one of the most widely used point-of-care (PoC) devices; however, their application in early disease diagnostics is often limited due to insufficient sensitivity for the requisite sample sizes and the short time frames of PoC testing. To address this, we developed a serum-stable, nanoparticle catalyst-labeled LFIA with a sensitivity surpassing t...

Characterization and optimization of gold nanoparticle-based silver-enhanced immunoassays.

Silver-enhanced nanoparticle-labeled immunoassays provide a simple, low-cost, and effective way of detecting antigens in dilute solutions. The physical mechanisms behind their operation, however, have not been fully investigated. We present a semiquantitative approach for optimizing sandwich nanoparticle immunoassays using an adsorption-controlled kinetic model. Primary antibodies were immobili...

The design and applications of nanoparticle coated microspheres in immunoassays.

Nanoparticle coated microspheres are composed of two or more materials with a core/shell structure and exhibit unique abilities that allow amplification of trace targets in immunoassays. The preparation of nanoparticle coated microspheres can be accomplished using three main strategies: (1) in-situ, (2) ex-situ, and (3) hollow sphere methods. Antibodies or biomolecules can be immobilized on the...

Oligonucleotide-linked gold nanoparticle aggregates for enhanced sensitivity in lateral flow assays.

Lateral flow assays (LFAs) as rapid analytical techniques promise to be widely used in point-of-care (POC) diagnostics because of their affordability and simplicity. However, LFAs still suffer from low sensitivity in detection of various biomarkers, e.g., nucleic acids. In this study, we developed a simple and general one-step signal amplification strategy, which employed oligonucleotide-linked...

Towards One-Step Quantitation of Prostate-Specific Antigen (PSA) in Microfluidic Devices: Feasibility of Optical Detection with Nanoparticle Labels

Rapid and quantitative prostate-specific antigen (PSA) biomarker detection would be beneficial to cancer diagnostics, improving early detection and therefore increasing chances of survival. Nanoparticle-based detection is routinely used in one-step nitrocellulose-based lateral flow (LF) immunoassays; however, it is well established within the scientific diagnostic community that LF technology l...
