Summary: The growing use of plastic materials has resulted in the accumulation of waste in marine environments, causing hazardous micro- and nanoplastics. These plastic particles absorb toxic pollutants, support bacterial growth, and spread through the food chain, posing serious risks to human health. Therefore, addressing nano/microplastics pollution is crucial, and self-propelled nano/microrobots have shown promise in their efficient removal. This review critically examines advanced strategies for nano/microplastics capture and degradation by autonomous nano/microrobots, as well as the challenges and future prospects of this research field.

Summary: This Review examines the properties of microplastic particles and discusses methods of assessing the risks they pose to humans and the environment. Microplastic particles are widespread in the environment and can be found in the air we breathe and the food we eat. The lack of a risk assessment framework that considers the multidimensionality of microplastic particles compared to natural particles is a key challenge. This article reviews current understanding of microplastic characteristics and effects and proposes a method for quantifying exposure and effect thresholds using probability density functions.

Summary: This study presents the spontaneous assembly of hematite-based microrobots with different shapes and showcases their fuel-free motion ability under light irradiation. The researchers discovered that microrobots with different shapes exhibit different assembly behavior and synchronized motions. These light-powered self-assembled microchains demonstrate innovative cooperative behavior and hold great potential for multitasking operations at a small scale.

Summary: This paper reviews the degradation characteristics and ecological effects of biodegradable plastics (BPs) and biodegradable microplastics (BMPs) in soil ecosystems. It reveals that BMPs have different or more severe impacts on soil environment compared to conventional microplastics (MPs), and BPs are not a perfect substitute for solving plastic pollution. Further research should focus on the generation, environmental behavior, ecological impact of BPs, and whether BMPs cause greater harm.

Summary: Researchers propose a triple-engine hybrid micromotor based on electric and magnetic fields for driving Mg-based micromotors. Electric fields can dynamically tune the micromotor mobility and be used for cell trapping, transport, and drug delivery. Magnetic rolling is used for self-propulsion and steering, as electric propulsion requires low conductivity mediums while Mg dissolution requires a low pH environment.

Summary: Concerns about the environmental fate and persistence of microplastics (MPs) are growing globally, especially in the context of bioplastics replacing petro-derived plastics. Poly(lactic acid) (PLA) is a pioneering bioplastic with multifunctional properties, but its degradation and behavior in the environment are not well understood. Research on the sorption capacities and toxicity of PLA MPs is limited, and future trends and gaps in knowledge need to be addressed.
