Here we describe a quick and simple method to measure cell stiffness. The general principle of this approach is to measure membrane deformation in response to well-defined negative pressure applied through a micropipette to the cell surface. This method provides a powerful tool to study biomechanical properties of substrate-attached cells.

Source: Matthysse, A. G. Adherence of Bacteria to Plant Surfaces Measured in the Laboratory. J. Vis. Exp. (2018).This video demonstrates the evaluation of bacterial attachment to plant roots using phase-contrast microscopy. Root samples from seedlings incubated with bacteria are first mounted to check for free bacteria. The samples are then washed to remove loosely attached bacteria and remounted using a suitable coverslip to prevent damage. Finally, the number of bacteria attached to the root...

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that physical...

Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...

This video demonstrates a viral attachment assay for screening antiviral compounds. Using genetically modified hepatitis C virus and luciferase, it assesses inhibitory effects on viral attachment, as indicated by lower light intensity in co-treated wells compared to wells treated with the virus alone.
FAQs
Initial contact occurs when structures on the bacterial cell surface interact with the substrate, creating weak, reversible contacts. These early interactions depend on the substrate’s chemistry, electrical charge, wettability, and topography. If conditions remain favorable, the cells can establish stronger adhesion and continue toward growth on the material.
Surface chemistry, charge, wettability, and topography each shape how bacterial cells interact with a material. Together, these properties influence whether cells make initial contact, remain associated with the surface, and develop stronger attachment. Controlling these features therefore gives bioengineers a way to encourage or limit colonization for a specific application.
The transition marks a shift from temporary association to a more established microbial community. Extracellular polymeric substances help support stronger adhesion as cells remain on the substrate and grow. This distinction matters because a surface that permits only initial contact may behave very differently from one that supports persistent biofilm development.
Researchers should relate the material’s chemistry, charge, wettability, and topography to observed bacterial attachment and subsequent growth. This connects measurable substrate characteristics with biological outcomes rather than treating adhesion as a property of the cells alone. Such characterization supports deliberate design of materials for either reduced colonization or sustained microbial activity.
For medical-device applications, researchers can use relationships between surface properties and bacterial colonization to design materials that discourage persistent attachment and biofilm development. Reducing favorable interactions at the interface may help limit microbial growth on the device. This approach connects bioengineering design with the goal of improving infection-resistant biomaterials.
Substrates are useful when bioengineers want to maintain bacterial activity rather than prevent colonization. Supporting attachment and growth can help organize microbial communities for biosensors, bioprocessing reactors, and environmental technologies. In these settings, the material serves as a controllable interface for studying or applying microbe-material interactions.
