Extensive research efforts are currently devoted to developing and improving conventional technologies for water treatment. Membrane-based water treatment technologies are among the most preferred options due to their commercial success, simple operation, low energy and space requirements, and high separation efficiency. Despite the advances made in membrane-based technologies, fouling remains a critical challenge. Fouling occurs upon the accumulation of unwanted impurities on the membrane surface and within the membrane pores which results in a significant decline in the membrane permeate flux. To alleviate the operational challenges from fouling, surface modification to develop antifouling membranes appears to be an effective technique. A comprehensive review of the surface modification techniques for the development of antifouling membranes is provided in this paper. chemical surface modification techniques (grafting and plasma treatment), physical modification techniques (blending, coating, adsorption, and thermal treatment), and combined physical and chemical modification techniques have been discussed. Moreover, the challenges related to surface modification and the future research directions are addressed.

Functionalizing chemotherapeutics-loaded liposomes with monoclonal antibodies can enhance their specificity and minimize side effects. Targeting the human epidermal growth factor receptor 2 (HER2), overexpressed in HER2-positive breast cancer, is achievable by coating liposomes with an anti-HER2 monoclonal antibody. This study focused on synthesizing doxorubicin (DOX)-loaded immunoliposomes functionalized with anti-HER2 (HER-lip). The release of the drug from these immunoliposomes was triggered by high-frequency ultrasound (HFUS) and microbubbles, which acted as exogenous cavitation-enhancing agents. The platform was evaluated for size, lipid content, protein concentration, stability, and controlled release profiles. In vitro assessments were also performed, including the MTT assay for cell viability and flow cytometry to evaluate drug uptake. This innovative drug delivery system shows potential for combined therapeutic and diagnostic applications, improving personalized cancer care and treatment. © 2024 IEEE.
