ALB and neoplasm: Recent development of technologies to utilize nanocarriers, such as polymeric nanoparticles, PEG-coated nanoparticles, colloid carrier systems, PLGA nanoparticles, and albumin microspheres, are being investigated in clinical studies to deliver HDACi with enhanced solubility, tumor specificity and less toxicity (Enriquez et al., 2013; Martin et al., 2013; Goswami et al., 2018; Bertrand et al., 2019; Lee et al., 2019).
