mallocusablesize

Mallocusable size is a term used in micro- and nanomanipulation to describe the largest dimension of an object that can be reliably manipulated by a mallocus-based mechanism under defined conditions. The term is a neologism introduced in discussions of active microassembly and contactless handling, where external fields, fluidic flows, or miniature robotic tools position small objects. The mallocusable size depends on the manipulation method, the properties of the surrounding medium, and the geometry of the object, and is typically reported for a specified success rate in controlled experiments.

Measurement and interpretation pan a central role. Mallocusable size is usually expressed in nanometers or micrometers and is determined by systematically testing whether objects of increasing size can be moved or held with acceptable precision. In practice, different techniques yield different thresholds: optical or magnetic tweezers in aqueous media, for example, may handle certain size ranges that differ from those achievable with dielectrophoretic or fluidic-jet methods. The measured value is influenced by factors such as viscosity, temperature, field strength, drag forces, and Brownian motion.

Applications and scope are broad within research and development. Understanding mallocusable size helps in designing microassembly workflows, evaluating the feasibility of particle-based delivery systems, and guiding the selection of manipulation methods for specific object sizes. Limitations include the strong dependence on environment and object shape, meaning mallocusable size is not universal and may vary across setups.
