The world had faced a leap in the field of science and technology to a great extent in the last five decades. The fabrication of materials is done in a more miniaturized way for merging the different aspects of the working field in a single device. The paper presents a review of different technologies that had been used electronically for the last two decades for the production of substances that...
In this work, we report a portable microfluidic chip based on gold nanoparticle-enhanced electrochemical detection for single-bacteria diognostic. The possibility of single-bacteria detection is realized here by using electroactive molecules modified on gold nanoparticles (NPs) to detect and differentiate Staphylococcus aureus and Pseudomonas aeruginosa. The detection limit of these two electroactive...
Electrochemical immunoassay involving two magnetic steps-separation of unbound nanoparticles from bacteria/antigen-Fe3O4 nanoparticles conjugates and concentrating of the conjugates on solid substrate is proposed. Carbon screen printed electrodes covered antibodies specific to Salmonella typhimurium (strain SL 7207) serves as the mentioned substrate. Immunocomplex formed is being solved in the mixture...
