Abstract
Membrane technology is playing a crucial role in cutting-edge innovations in the biomedical field. One such innovation is the surface engineering of a membrane for enhanced longevity, efficient separation, and better throughput. Hence, surface engineering is widely used while developing membranes for its use in bioartificial organ development, separation processes, extracorporeal devices, etc. Chemical-based surface modifications are usually performed by functional group/biomolecule grafting, surface moiety modification, and altercation of hydrophilic and hydrophobic properties. Further, creation of micro/nanogrooves, pillars, channel networks, and other topologies is achieved to modify physio-mechanical processes. These surface modifications facilitate improved cellular attachment, directional migration, and communication among the neighboring cells and enhanced diffusional transport of nutrients, gases, and waste across the membrane. These modifications, apart from improving functional efficiency, also help in overcoming fouling issues, biofilm formation, and infection incidences. Multiple strategies are adopted, like lysozyme enzymatic action, topographical modifications, nanomaterial coating, and antibiotic/antibacterial agent doping in the membrane to counter the challenges of biofilm formation, fouling challenges, and microbial invasion. Therefore, in the current review, we have comprehensibly discussed different types of membranes, their fabrication and surface modifications, antifouling/antibacterial strategies, and their applications in bioengineering. Thus, this review would benefit bioengineers and membrane scientists who aim to improve membranes for applications in tissue engineering, bioseparation, extra corporeal membrane devices, wound healing, and others.

Abstract
We present the first digital microfluidic (DMF) antimicrobial susceptibility test (AST) using an optical oxygen sensor film for in-situ and real-time continuous measurement of extracellular dissolved oxygen (DO). The device allows one to monitor bacterial growth across the entire cell culture area, and the fabricated device was utilized for a miniaturized and automated AST. The oxygen-sensitive probe platinum(II)-5,10,15,20-tetrakis-(2,3,4,5,6-pentafluorophenyl)-porphyrin was embedded in a Hyflon AD 60 polymer and spin-coated as a 100 nm thick layer onto an ITO glass serving as the DMF ground electrode. This DMF-integrated oxygen sensing film was found to cause no negative effects to the droplet manipulation or cell growth on the chip. The developed DMF platform was used to monitor the DO consumption during Escherichia coli (E. coli) growth caused by cellular respiration. A rapid and reliable twofold dilution procedure was developed and performed, and the AST with E. coli ATCC 25922 in the presence of ampicillin, chloramphenicol, and tetracycline at different concentrations from 0.5 to 8 μg mL-1 was investigated. All sample dispensation, dilution, and mixing were performed automatically on the chip within 10 min. The minimum inhibitory concentration values measured from the DMF chip were consistent with those from the standard broth microdilution method but requiring only minimal sample handling and working with much smaller sample volumes.
