Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Magnetic drug targeting is a method to steer and concentrate magnetic nanoparticles (MNPs) in a desired location in body. In our recent work, we have investigated the effective parameters of a field function to improve the process effectiveness. In this paper, based on the assessment and experimental process, in fact, we focus on proposing a modified version of Field Function (MVFF) to improve the guidance system consistent with experimental facts. We will use an electromagnetic actuator (EMA) system which consists of two coil-core system. The cores are added in the center of each coil to concentrate the flux in the region of interest. Effective guidance of MNPs is demonstrated via simulations and experiments using 750-nm-diameter MNPs (SiMAG-Silanol 1101 of Chemicell Company) in a 1 mm Y-shaped channel. To evaluate the effectiveness of the MVFF, the concentration of correct outlet and incorrect outlet has been measured using the experimental set up it has been proven that the proposed MVFF demonstrates a move efficient results.
