Negative regulation of violacein biosynthesis in Chromobacterium violaceum [PDF]

, 2017
In Chromobacteium violaceum, the purple pigment violacein is under positive regulation by the N-acylhomoserine lactone CviI/R quorum sensing system and negative regulation by an uncharacterized putative repressor.

Towards Recycled Paper Based Impedance Biosensor with Wireless Readout

, 2017
Results are presented regarding the development of recycled paper based impedance biosensors with screen printed interdigitated electrode structures (IDES). The sensors show a response to increasing salt concentrations in the range 30–100 mM NaCl.

Regulation of human pancreas hormone secretion by autonomic innervation [PDF]

, 2012
Diabetes mellitus is a silent killer doing away with one person every 10 seconds. We speak of diabetes when the organism cannot control the right level of glucose in the blood.

CD11c-expressing Ly6C+CCR2+ monocytes constitute a reservoir for efficient Leishmania proliferation and cell-to-cell transmission

PLoS Pathogens, 2018
The virulence of intracellular pathogens such as Leishmania major (L. major) relies largely on their ability to undergo cycles of replication within phagocytes, release, and uptake into new host cells.

Highly Multiplexed Label-Free Imaging Sensor for Accurate Quantification of Small-Molecule Binding Kinetics

ACS Omega, 2020
Investigating the binding interaction of small molecules to large ligands is a compelling task for the field of drug development, as well as agro-biotechnology, since a common trait of drugs and toxins is often a low molecular weight (MW).

Biosensing:how citizens’ views illuminate emerging health and social risks [PDF]

, 2016
This article explores material from a citizen’s inquiry into the social and ethical implications of health biosensors. In ‘Our Bodies, Our Data’ a space was afforded for members of the public to examine two forms of health biosensing, and for the authors
