Soft, untethered microrobots composed of biocompatible materials for completing micromanipulation and drug delivery tasks in lab-on-a-chip and medical scenarios are currently being developed. Alginate holds significant potential in medical microrobotics due to its biocompatibility, biodegradability, and drug encapsulation capabilities. Here, we describe the synthesis of MANiACs—Magnetically Aligned Nanorods in Alginate Capsules—for use as untethered microrobotic surface tumblers, demonstrating magnetically guided lateral tumbling via rotating magnetic fields. MANiAC translation is demonstrated on tissue surfaces as well as inclined slopes. These alginate microrobots are capable of manipulating objects over millimeter-scale distances. Finally, we demonstrate payload release capabilities of MANiACs during translational tumbling motion.

Lifestyle segmentation, used to explore consumer attitudes, interests, opinions and values, is applied to a local farmers’ market (the Otago farmers’ market, in New Zealand) in order to build a profile of consumer motivations and behavioural drivers beyond simple demographic data. Prior research indicates a growing need for studies that seek to understand the intangible aspects of food selection and consumption. Farmers’ market consumers are often treated as a homogenous group, with purchase and consumption decision making assumed to rest with tangible aspects of produce on offer, such as its organic nature or lower cost. The overall experience of the consumer within the food purchase environment is often overlooked. The current study finds that three distinctly different consumer segments exist within the farmers’ market context, with those concerned with the tangible aspects of produce being the smallest group of consumers. Two consumer segments driven by differing experience-related motivations give the greatest insight into consumer behaviour in a farmers’ market context, with committed, loyal consumers being concerned with relationships with sellers and producers, and experience orientated consumers motivated by the opportunity to interact with other farmers’ market attendees.
