Giant magnetoresistive sensors and superparamagnetic nanoparticles: a chip-scale detection strategy for immunosorbent assays.
TL;DR: This paper examines magnetic labeling methodologies and surface derivatization approaches based on protein-protein binding that are aimed at forming a general set of protocols to move GMR concepts into the bioanalytical arena in terms of sensitivity, detection limits, and potential for multiplexing.

TL;DR: The utilization of giant magnetoresistive sensors for the detection of streptavidin-coated magnetic particles that are selectively captured by biotinylated gold addresses on a 2 x 0.3 cm sample stick is described, along with the potential use of Streptavid in-coating magnetic particles as a universal label for antigen detection in, for example, heterogeneous assays.

TL;DR: This work describes the construction and testing of a first-generation instrument that uses a GMR sensor network to read the response of a "simulated" sample stick, and assessed the merits of using on-sample standards as internal references as a facile means to account for small variations in the gap between the sample stick and sensor.

Microfabricated tools for manipulation and analysis of magnetic microcarriers
TL;DR: In this paper, the authors developed tools for manipulating and detecting magnetic microcarriers with microscale features, such as giant magnetoresistive (GMR) sensors and wires for detection, and for creating high local field gradients.
