Abstract
We introduce the use of block copolymer membranes for an emerging application, "drug capture". The polymer is incorporated in a new class of biomedical devices, referred to as ChemoFilter, which is an image-guided temporarily deployable endovascular device designed to increase the efficacy of chemotherapy-based cancer treatment. We show that block copolymer membranes consisting of functional sulfonated polystyrene end blocks and a structural polyethylene middle block (S-SES) are capable of capturing doxorubicin, a chemotherapy drug. We focus on the relationship between morphology of the membrane in the ChemoFilter device and efficacy of doxorubicin capture measured in vitro. Using small-angle X-ray scattering and cryogenic scanning transmission electron microscopy, we discovered that rapid doxorubicin capture is associated with the presence of water-rich channels in the lamellar-forming S-SES membranes in aqueous environment.

Abstract
The three dimensional (3D) cell culture in polymer-based micro system has become a useful tool for in vitro drug discovery. Among those polymers, polysulfone hollow fiber membrane (PSf HFM) is commonly used to create a microenvironment for cells. However, the target drug may adsorb on the polymeric surface, and this elicits negative impacts on cell exposure due to the reduced effective drug concentration in culture medium. In order to reduce the drug adsorption, PSf membrane were modified with hydrophilic Pluronic (PEO-b-PPO-b-PEO) copolymers, L121, P123 and F127 (PEO contents increase from 10%, 30% to 70%), by physical adsorption. As a result, the hydrophilicity of HFMs increased at an order of PSf<L121<P123<F127 HFMs, while the negative surface charge decreased at the order of PSf>F127>P123>L121 HFMs. The three modified membrane all showed significant resistance to adsorption of acid/neutral drugs. More importantly, the adsorption of base drugs were largely reduced to an average value of 11% on the L121 HFM. The improved resistance to drug adsorption could be attributed to the synergy of hydrophobic/neutrally charged PPO and hydrophilic PEO. The L121 HFM was further assessed by evaluating the drug hepatotoxicity in 3D culture of hepatocytes. The base drugs, clozapine and doxorubicin, showed more sensitive hepatotoxicity on hepatocytes in L121 HFM than in PSf HFM, while the acid drug, salicylic acid, showed the similar hepatotoxicity to hepatocytes in both HFMs. Our finding suggests that PSf HFM modified by PEO-b-PPO-b-PEO copolymers can efficiently resist the drug adsorption onto polymer membrane, and consequently improve the accuracy and sensitivity of in vitro hepatotoxic drug screening.

Abstract
Hybrid particles are a class of materials that include both organic and inorganic moieties at the same time and possess interesting magnetic, optical and mechanical properties. Extensive research is being carried out to develop soft hybrid nanoparticles utilizing their superparamagnetic, biodegradable and fluorescence properties and to explore their biomedical applications. This chapter discusses the important methods for the development of different types of soft hybrid nanoparticles, including polymer immobilization on preformed particles, adsorption of polymers on colloidal particles, adsorption of polymers via layer-by-layer self-assembly, adsorption of nanoparticles on colloidal particles, chemical grafting of preformed polymers, polymerization from and on to colloidal particles, click chemistry, atom-transfer radical polymerization (ATRP), reversible addition–fragmentation chain-transfer radical (RAFT) polymerization, nitroxide-mediated polymerization (NMP) and conventional seed radical polymerization. With current rapid advances in nanomedicine, colloidally engineered hybrid particles are gaining immense importance in fields such as cancer therapy, gene therapy, disease diagnosis and bioimaging. The applications of soft hybrid nanoparticles with respect to diagnosis are discussed briefly and a comprehensive account of their applications in the capture and extraction of nucleic acids, proteins and viruses is presented in this chapter.

Abstract
Hybrid anion exchange hollow fiber membranes (HAEHFMs) based on bromomethylated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO) are proposed as potential drug carriers for four anionic model drugs, including the sodium salts of benzoate (NaBS), salicylate (NaSA), meta-amino salicylate (NaMAS), and loxoprofen (NaLS). The results of the static loading and release experiments suggest that electrostatic interaction, hydrogen bonding, and hydrophobic interaction are the main interaction patterns between the membrane and the drugs. And they are directly influenced by the external phase conditions and the drug physicochemical characteristics, such as structure, molecular weight, dissociation (pKa), and hydrogen bonding capability. Among the four different drugs, NaSA and NaMAS appear to be the most suitable for controlled release by the HAEHFM due to their excellent adsorption/release behaviors.

Abstract
Isolation of acidic and basic model drugs by using pH sensitive poly(acrylic acid) grafted poly(vinylidene fluoride) (PAA-PVDF) cation-exchange membrane from biological fluids was reported. Effects of drug charge and lipophilicity on adsorption were also investigated. In the present study, basic model drugs adsorbed to a considerably greater extent onto the membrane than acidic drugs. Albumin was not adsorbed onto the membrane. Results of our study exposed, that electrostatic interactions between positively charged basic drug and negatively charged PVDF-PAA membrane were the most important factor affecting drug adsorption onto the membrane. Adsorption of acidic and basic drugs onto the PVDF-PAA membrane was not related to drug lipophilicity. The results of present study demonstrated that basic drugs adsorbed extensively onto the membrane, but albumin did not, proposing that PAA-PVDF membrane may be suitable for isolating basic drugs from proteinaceous biological fluids (i.e. serum) for subsequent monitoring and evaluation.

Abstract
The influence of charge and lipophilicity of acidic and basic model drugs on their adsorption onto poly(N,N-dimethyl aminoethyl methacrylic acid) grafted poly(vinylidene fluoride) (DMAEMA-PVDF) membranes was evaluated. The effect of serum proteins (albumin, IgG) and hormones (cortisol, free thyroxine (T(4)F) and thyrotropin (TSH)) on drug adsorption was also studied. Acidic model drugs (antiepileptics and benzodiazepies) adsorbed to a greater extent onto the membrane from Hepes buffer at ionic strength of 25mM and pH 7.0 than basic drugs (antidepressants) did. Adsorption of acidic model drugs was based on electrostatic interactions between positively charged tertiary amino groups of DMAEMA side-chain and acidic negatively charged drug. Albumin diminished the adsorption of drugs from serum onto the membrane. Lipophilicity was related to the adsorption of acidic model drugs from serum onto the membrane. The degree of grafting had the greatest effect on adsorption of lipophilic drugs, but no influence was observed on adsorption of hydrophilic drugs. The present results showed that acidic drugs and albumin adsorbed onto the membrane, which suggests that the PVDF-DMAEMA membrane may be suitable for separating acidic drugs from protein-free substances for subsequent monitoring and evaluation.

Abstract
Ion-exchange resins (IER), or ionic polymer networks, have received considerable attention from pharmaceutical scientists because of their versatile properties as drug-delivery vehicles. In the past few years, IER have been extensively studied in the development of novel drug-delivery systems (DDSs) and other biomedical applications. Some of the DDSs containing IER have been introduced into the market. In this review, the applications of IER in drug delivery research are discussed.
