Abstract: Disclosed are the cation polymers capable of removing their positive charges in oxidative conditions, preparation methods, and applications as gene delivery carriers. The oxidation-responsive unit is the p-(boronic acid or ester)benzylammonium, which upon oxidation eliminates p-hydroxymethlphenol and thus converts in a tertiary amine. Compared with the prior art, different from a common quaternary amination carrier, the synthesized charge reversal type gene delivery carrier for oxidative response of the present invention has a large quantity of positive charges and can well coat a DNA, but the positive charges can be removed under the condition of intracellular oxidation when the charge reversal type gene delivery carrier enters a cell, a charge reverse is triggered, the positive charges turn to negative charges, and the DNA is quickly released for transfection. The carrier is efficient, low in toxicity, and good in application prospect.

Abstract: Described are charge reversible polymers, peptides and their resulting colloidal particles, comprising polymers and peptides having primary and secondary amines that are protected as easily hydrolysable amides. The amides are charge-reversible such that at neutral pH they are negatively charged but become positively charged at pH less than 6 and thus are relatively stable at neutral pH but quickly hydrolyze at pH below 6. Incorporating a drug in a micelle or a polymer comprised of the charge-reversible polymers or peptides provides a drug carrier for delivering the drug preferentially to the solid tumor or other targeted cells.

Abstract: The invention is a nanoparticle that contains an anticancer drug that is released in cancer cells when administered to a subject. The nanoparticles have a core including the anticancer drug and polymer chains that are soluble at the pH of the cancer cell. The core is surrounded by a layer of polymer chains that are insoluble at the pH of healthy tissue but soluble at the pH of the cancer interstitium. An outside layer is made of water-soluble polymer chains to shield the nanoparticle from RES recognition and give the nanoparticle a long circulation time in the bloodstream of the subject. The outside layer may also include folic acid moieties that bind folic acid receptors on the surface of the cancer cell.

Abstract: A low-pressure multifunctional filter separates CO2 and other air pollutants from flue, coal, natural and other gas mixtures. The separation agent is a solid carbon-rich sorbent, such as coke, charcoal, coal or activated carbon, that captures CO2 and other air pollutants at lower temperatures and liberates them at higher temperatures. The sorbent is regenerated by heating with direct steam, hot CO2 or other source of thermal energy. The recovered CO2-rich product can be used for enhanced oil recovery, enhanced methane recovery, and subsequent storage in depleted oil and gas reservoirs.
