Bacterial mechanosensing: the force will be with you

Whether bacteria are in the planktonic state free-swimming or free-floating in liquid or in the biofilm state sessile on surfaces they are always subject to mechanical forces The long successful evolutionary history of bacteria implies that they are capable of adapting to varied mechanical forces and probably even actively respond to mechanical cues in their changing environments

Bacteria are able to communicate through the use of small molecule chemical messengers in a process referred to as 'quorum sensing' 45 The dense packing of cells in bacterial communities facilitates an increase in the concentration of small molecules that transfer information between cells and trigger physiological changes 46 The shape of chemical gradients in close proximity to surfaces

A Current View of Functional Biomaterials for Wound Care

The surface interaction between biomaterials and the damaged tissue occurs at various length scales from the organ (millimeters to centimeters) and tissue scale (millimeters) to the scale of individual cells (micrometers) and proteins (nanometers) [38 39] A tissue or part of an organ can be in contact with a biomaterial-based ECM or dressing for weeks and in the case of organs even up to

Invention – Tech Explorist

Engineered surfaces that reduce the adhesion proliferation and spread of bacteria have promise as a mean of preventing infections and reducing the use of antibiotics To address this need scientists created a flexible plastic wrap that can repel all forms of bacteria preventing the transfer of antibiotic-resistant superbugs and other dangerous bacteria in settings ranging from hospitals to

New Surface Strategies to Resist Remove and Recover

As the major species of biomacromolecule on bacteria surfaces EPS is expected to play an important role in multiple stages of bacteria adhesion processes P aeruginosa PA01 isogenic strains were used to study the connections between EPS production and bacteria adhesion Regular SPR was used to study preconditioning of biomacromolecules in bacteria culture while long-range SPR to study the

Surfaces are important because all restorative biomaterials meet and interact with the tooth structure at a surface Also all dental surfaces interact with intraoral constituents such as saliva and bacteria Changing a material's surface properties can mitigate the extent of that interaction The type of interaction between two materials at an interface is defined as the energy of

Transfer of bacteria between biomaterials surfaces

Bacterial adhesion to and transfer between surfaces is a complicated process With regard to the success of biomaterials implants studies on bacterial adhesion and transfer should not be confined to biomaterials surfaces in the human body but also encompass surfaces in the operating room where the origin of many biomaterials related infections is found The purpose of this study was to
