Title: Chitosan nanomagnets for eff ective extraction and sensitive mass spectrometric detection of pathogenic bacterial endotoxin from human urineThis work demonstrates the technology for the recovery of trace levels of endotoxin from urine samples and their detection using MALDI-MS. CuFeO 2 @chitosan nanomagnets showed 250 times more sensitivity compared to MALDI-MS conventional technique for separation and detection of endotoxin from urine.

This study demonstrates that graphene nanoflakes can be efficiently used as a successful, interference free matrix for matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS).

In this paper, we have attempted the use of MALDI-MS for the detection of bacteria from complex real world samples such as the root nodules of plants.

MALDI-MS was used for studying the impact of zinc oxide (ZnO) nanomaterial on Pseudomonas aeruginosa and Staphylococcus aureus. The growth pattern of both these bacterial pathogens in the presence of...
