Recently, anisotropic particles have attracted attention because their unique topology, functions and wide applications. Here, a new type of acrylate copolymer microspheres (AcPMs) with anisotropic wrinkled surface was synthesized with conventional monomers through two-step self-assembly in one-pot with regulating reaction media. First, butyl acrylate (BA), methyl methacrylate (MMA) and methacrylic acid (MAA) were copolymerized in EtOH/H 2 O solvent. Second, styrene (St) and BA were further copolymerized with increasing H 2 O proportion in solution, which enable AcPMs with emulsifiability. Its structure and morphology were characterized by FT-IR, SEM, XRD and DLS. The surface-wrinkled and anisotropic AcPMs was used as carrier to conjugate with AgNPs by in-situ reduction of silver ions (Ag + ), which afforded the AcPMs conjugating AgNPs (AgNPs@AcPMs), and it presented an excellent antibacterial activity against S. aureus and E. coli. Hence, AcPMs revealed strong potential in the biomedical fields.

“…While PNPs offer numerous advantages, including cost-effectiveness, low toxicity, and exceptional durability, they also have the potential to inhibit microbial activity. Li et al achieved the successful synthesis of antimicrobial materials through the conjugation of PNPs with Salphen Ce (IV) complexes (HSpCe) [136]. The research revealed that HSpCe@PNPs exhibited exceptional antibacterial efficacy, surpassing that of HSpCe alone.…”

After polymer flooding, substantial oil and residual polymers remain in reservoirs, leading to plugging and reduced recovery. MEOR (Microbial Enhanced Oil Recovery) aims to release trapped oil by utilizing microorganisms and their byproducts. The microorganisms can use residual HPAM (hydrolyzed polyacrylamide) as an energy source for polymer degradation, addressing reservoir plugging issues and improving oil recovery. However, microorganisms are sensitive to environmental conditions. This paper presents a detailed update of MEOR, including microbial products, mechanisms, and merits and demerits. The effect of the displacement fluid and conditions on microorganisms is thoroughly demonstrated to elucidate their influencing mechanism. Among these factors, HPAM and crosslinkers, which have significant biological toxicity, affect microorganisms and the efficiency of MEOR. Limited research exists on the effect of chemicals on microorganisms’ properties, metabolism, and oil displacement mechanisms. The development of microbial consortium, their metabolic interaction, and oil displacement microprocesses are also discussed. In addition, prior studies lack insights into microorganisms’ interaction and mechanisms using chemicals. Finally, field trials exist to examine the microbial consortium’s efficiency and introduce new technologies. This review mainly explores the influencing factors on microorganisms, and confirms the credibility of MEOR after polymer flooding, providing a scientific basis for improving the theory of MEOR.
