From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

Advanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Quorum sensing in human gut and food microbiomes: Significance and potential for therapeutic targeting

Frontiers in Microbiology, 2022
Human gut and food microbiomes interact during digestion. The outcome of these interactions influences the taxonomical composition and functional capacity of the resident human gut microbiome, with potential consequential impacts on health and disease ...

Quorum sensing going wild

iScience, 2023
The first discovered and well-characterized bacterial quorum sensing (QS) system belongs to Vibrio fischeri, which uses N-acyl homo-serine lactones (AHLs) for cell-cell signaling. AHL QS cell-cell communication is often regarded as a cell density-dependent regulatory switch.

Synthesis of majucin-type sesquiterpenes and immobilization and visualization of quorum sensing signaling molecules [PDF]

, 2014
The science of chemical biology is the ability to answer biological questions by analyzing living systems at the chemical level. Two entirely different approaches to reach this goal are presented in this thesis.

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

Research progress on quorum sensing in the caries-causing effects of Streptococcus mutans and Candida albicans [PDF]

口腔疾病防治
Dental caries is a major disease that seriously endangers human oral health. Dental plaque biofilm composed of many microorganisms is the primary factor of dental caries. Inhibiting biofilm formation has become the focus of research on the prevention and

alpha-Hydroxyketone Synthesis and Sensing by Legionella and Vibrio [PDF]

, 2012
Bacteria synthesize and sense low molecular weight signaling molecules, termed autoinducers, to measure their population density and community complexity. One class of autoinducers, the α-hydroxyketones (AHKs), is produced and detected by the water-borne

Biofilm‐Binding Phages Enhance Biofilm Eradication by Synergistic Photothermal and Photodynamic Therapy

Advanced Science, EarlyView.
Engineered phage‐based trifunctional nanofibers are developed for synergistic biofilm eradication. Biofilm‐binding phages, armed with AuNPs and TCPP, serve as both warheads and scaffolds, endowing the phototherapy agents with biofilm‐anchoring ability. Upon light irradiation, AuNPs induce photothermal therapy, while TCPP generates 1O2 for photodynamic ...

Thermoresponsive carbohydrate polymer mucoadhesive gel for synergistic delivery of acarbose and fluconazole against Candida biofilms

Scientific Reports
The emerging threat of drug-resistant Candida albicans, especially in recurrent vulvovaginal candidiasis (VVC) biofilms, has revealed weaknesses in existing monotherapeutic antifungal treatments.

Quorum sensing influences Vibrio harveyi growth rates in a manner not fully accounted for by the marker effect of bioluminescence.

PLoS ONE, 2008
BackgroundThe light-emitting Vibrios provide excellent material for studying the interaction of cellular communication with growth rate because bioluminescence is a convenient marker for quorum sensing.
