Bioelectronic Nanodevices Fabricated on Live Bacteria

Microencapsulation of live probiotic bacteria.

Scientific research regarding the use of live bacterial cells for therapeutic purposes has been rapidly growing over the years and has generated considerable interest to scientists and health professionals. Probiotics are defined as essential live microorganisms which, when administered in adequate amounts, confer a health benefit on the host. Due to considerable beneficial health effects, thes...

Bioelectronic Noses Based on Olfactory Receptors

Single-molecule imaging in live bacteria cells.

Bacteria, such as Escherichia coli and Caulobacter crescentus, are the most studied and perhaps best-understood organisms in biology. The advances in understanding of living systems gained from these organisms are immense. Application of single-molecule techniques in bacteria have presented unique difficulties owing to their small size and highly curved form. The aim of this review is to show a...

Lactic acid bacteria as live vaccines.

Mucosal routes for vaccine delivery offer several advantages over systemic inoculation from both immunological and practical points of view. The development of efficient mucosal vaccines therefore represents a top prority in modern vaccinology. One way to deliver protective antigens at the mucosal surfaces is to use live bacterial vectors. Until recently most of these were derived from attenuat...

Storm clouds are full of live bacteria

“The organic substances we have found occur in sufficiently large quantities to support bacterial growth. This turns the droplets into small dynamic universes, each of which supports certain forms of life,” says Tina Santl Temkiv, who conducted the new study as a PhD student together with her supervisor, senior researcher Ulrich Bay Gosewinkel, at Aarhus University’s Department of Environmental...
