Rastegar G, Salman MM, Sirsi SR. Remote Loading: The Missing Piece for Achieving High Drug Payload and Rapid Release in Polymeric Microbubbles. Pharmaceutics 2023; 15:2550.

Abstract
The use of drug-loaded microbubbles for targeted drug delivery, particularly in cancer treatment, has been extensively studied in recent years. However, the loading capacity of microbubbles has been limited due to their surface area. Typically, drug molecules are loaded on or within the shell, or drug-loaded nanoparticles are coated on the surfaces of microbubbles. To address this significant limitation, we have introduced a novel approach. For the first time, we employed a transmembrane ammonium sulfate and pH gradient to load doxorubicin in a crystallized form in the core of polymeric microcapsules. Subsequently, we created remotely loaded microbubbles (RLMBs) through the sublimation of the liquid core of the microcapsules. Remotely loaded microcapsules exhibited an 18-fold increase in drug payload compared with physically loaded microcapsules. Furthermore, we investigated the drug release of RLMBs when exposed to an ultrasound field. After 120 s, an impressive 82.4 ± 5.5% of the loaded doxorubicin was released, demonstrating the remarkable capability of remotely loaded microbubbles for on-demand drug release. This study is the first to report such microbubbles that enable rapid drug release from the core. This innovative technique holds great promise in enhancing drug loading capacity and advancing targeted drug delivery.

Abstract
Engineering of colloidal particles and capsules despite substantial progress is still facing a number of unsolved issues including low loading capacity, non-uniform size and shape of carriers, tailoring different functionalities and versatility to encapsulated cargo. In this work, we propose a method for defined-shaped functionally asymmetric polymer capsule fabrication based on a soft lithography approach. The developed capsules consist of two classes of polymers - the main part "cup" is made out of polyelectrolyte multilayers (PAH-PSS) and "lid" is made of biodegradable polyether (PLGA). Asymmetric capsules combine advantages from both traditional layer-by-layer capsules and recently developed printed "pelmeni" capsules. This combination provides stimuli-responsiveness due to polyelectrolyte multilayer properties differing from PLGA. The inner volume of capsules can be loaded with a variety of active compounds and the capsule's geometry is defined due to the soft-lithography method. Capsules have a core-shell structure and monodisperse size distribution. Three methods to trigger cargo release have been demonstrated, namely temperature treatment, ultrasonication and pH shift. Steroidal drug dexamethasone was used to illustrate the applicability of the systems for triggered drug release. The application of proposed asymmetric capsules includes but is not limited to pharmacology, diagnostics, sensors, micro- and nanoreactors and chemical actuators.

Abstract
We report a simple process to fabricate monodisperse tetra-arm poly(ethylene glycol) (tetra-PEG) hydrogel microcapsules with an aqueous core and a semipermeable hydrogel shell through the formation of aqueous two-phase system (ATPS) droplets consisting of a dextran-rich core and a tetra-PEG macromonomer-rich shell, followed by a spontaneous cross-end coupling reaction of tetra-PEG macromonomers in the shell. Different from conventional techniques, this process enables for the continuous production of hydrogel microcapsules from water-in-oil emulsion droplets under mild conditions in the absence of radical initiators and external stimuli such as heating and ultraviolet light irradiation. We find that rapid cross-end coupling reaction of tetra-PEG macromonomers in ATPS droplets in the range of pH from 7.4 to 7.8 gives hydrogel microcapsules with a kinetically arrested core-shell structure. The diameter and core-shell ratio of the microcapsules can be easily controlled by adjusting flow rates and ATPS compositions. On the other hand, the slow cross-end coupling reaction of tetra-PEG macromonomers in ATPS droplets at pH 7.0 and lower induces structural change from core-shell to Janus during the reaction, which eventually forms hydrogel microparticles with a thermodynamically stable crescent structure. We believe that these hydrogel microparticles with controlled structures can be used in biomedical fields such as cell encapsulation, biosensors, and drug delivery carriers for sensitive biomolecules.

Abstract
In this work, we developed a novel active targeting and pH-responsive system for delivering the drug doxorubicin (DOX) to tumor sites using folic acid (FA)-modified multiwalled carbon nanotubes (MWCNTs). Acid-treated MWCNTs with carboxyl groups were first covalently conjugated with polyethyleneimine (PEI). Subsequent sequential modification with FA (via a polyethylene glycol spacer), fluorescein isothiocyanate (FI), and acetic anhydride/triethylamine resulted in multifunctional FA-bound MWCNT (MWCNT-PEI.Ac-FI-PEG-FA) nanomaterials that possessed exceptional colloidal stability and good biocompatibility in a given concentration range. The FA-bound MWCNTs were characterized using various techniques and exhibited a high drug loading and an encapsulation efficiency as high as 70.4%. DOX/MWCNT-PEI.Ac-FI-PEG-FA nanocomplexes (DOX/MWCNT NCs) exhibited pH-responsive release in acidic environments. Importantly, the DOX/MWCNT NCs targeted tumor cells overexpressing FA receptors (FARs) and effectively inhibited their growth. In vivo anticancer experiments demonstrated that DOX/MWCNT NCs not only enhanced the suppression of tumor growth but also decreased the side effects of free DOX. The developed FA-modified MWCNTs with an unconventionally high DOX loading boosted in vivo anti-tumor efficacy, and the lower systemic toxicity may be utilized for tumor therapy upon clinical translation.

Abstract
Doxorubicin is an effective and widely used cancer chemotherapeutic agent, but its application is greatly compromised by its cumulative dose-dependent side effect of cardiotoxicity. A gold nanoparticle-based drug delivery system has been designed to overcome this limitation. Five novel thiolated doxorubicin analogs were synthesized and their biological activities evaluated. Two of these analogs and PEG stabilizing ligands were then conjugated to gold nanoparticles, and the resulting Au-Dox constructs were evaluated. The results show that release of native drug can be achieved by the action of reducing agents such as glutathione or under acidic conditions, but reductive drug release gave the cleanest drug release. Gold nanoparticles (Au-Dox) were prepared with different loadings of PEG and doxorubicin, and one formulation was evaluated for mammalian stability and toxicity. Plasma levels of doxorubicin in mice treated with Au-Dox were significantly lower than in mice treated with the same amount of doxorubicin, indicating that the construct is stable under physiological conditions. Treatment of mice with Au-Dox gave no histopathologically observable differences from mice treated with saline, while mice treated with an equivalent dose of doxorubicin showed significant histopathologically observable lesions.

Abstract
This paper reports on a novel microfluidic technique for the fabrication of microspheres of synthetic polymers including poly(vinyl chloride) (PVC), poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), poly(lactic acid) (PLA), and polystyrene (PS). The polymers are dissolved in tetrahydrofuran (THF) and the method is based on the diminished solubility of THF in a 20% (w/v) NaCl solution which allows the formation of droplets of the polymer solution. These polymer solution droplets are generated in a microfluidic system and their desolvation is accomplished within seconds by allowing the droplets to rise by buoyancy through a NaCl solution with a concentration lower than 15%. The size and morphology of the resultant polymer microspheres have been investigated by optical and scanning electron microscopy. Apart from the elimination of the use of highly toxic solvents as in conventional methods for manufacturing of polymer microspheres, the newly developed technique has the advantages of providing faster desolvation of the polymer solution droplets and a higher yield of microspheres compared to emulsification-based techniques.

Abstract
Biodegradable micelle systems with both extracellular stabilities and specific targeting properties are highly desirable for anti-cancer drug delivery. Here, we report a biodegradable and crosslinkable poly(propylene fumarate)-co-poly(lactide-co-glycolide)-co-poly(ethylene glycol) (PPF-PLGA-PEG) copolymer conjugated with folate (FA) molecules for receptor-mediated delivery of doxorubicin. Micelles with folate ligands on surface and fumarate bonds within the core were self-assembled and crosslinked, which exhibited better stability against potential physiological conditions during and after drug administration. A pH sensitive drug release profile was observed showing robust release at acidic environment due to the ester hydrolysis of PLGA (50:50). Further, micelles with folate ligands on surface showed strong targeting ability and therapeutic efficacy through receptor-mediated endocytosis, as evidenced by efficacious cancer killing and fatal DNA damage. These results imply promising potential for ligand-conjugated core crosslinked PPF-PLGA-PEG-FA micelles as carrier system for targeted anti-cancer drug delivery.

Abstract
Novel biodegradable and crosslinkable copolymers of hydrophobic poly(propylene fumarate)-co-poly(lactic-co-glycolic acid) (PPF-PLGA) linked with hydrophilic poly(ethylene glycol) (PEG), namely PPF-PLGA-PEG, were developed and fabricated into core-shell nanoparticles through self-assembly and photocrosslinking. A fluorescent probe, rhodamine B (RhB), was conjugated to the end of the copolymer chain (PPF-PLGA-PEG-RhB), which allows tracking of the nanoparticles through visualizing the fluorescence probe. Folic acid (FA) ligand was conjugated to another series of chains (PPF-PLGA-PEG-FA) for targeted delivery of the nanoparticles to the tumor sites by binding to the ubiquitously overexpressed FA receptors on tumor cells. Our results showed that PPF-PLGA-PEG nanoparticles incorporated with RhB fluorescence probes and FA tumor binding ligands have specific cancer cell targeting and imaging abilities. These crosslinkable nanoparticles are potentially useful to serve as a platform for conjugation of fluorescence probes as well as various antibodies and peptides for cancer targeted imaging or drug delivery.

Abstract
By enabling nanoparticle-based drug delivery system to actively target cancer cells with high selectivity, active targeted molecules have attracted great attention in the application of nanoparticles for anticancer drug delivery. However, the clinical application of most active targeted molecules in breast cancer therapy is limited, due to the low expression of their receptors in breast tumors or coexpression in the normal and tumor breast tissues. Here, a neuropeptide Y Y1 receptors ligand PNBL-NPY, as a novel targeted molecule, is conjugated with anticancer drug doxorubicin encapsulating albumin nanoparticles to investigate the effect of Y1 receptors on the delivery of drug-loaded nanoparticles to breast cancer cells and its potential for breast cancer therapy. The PNBL-NPY can actively recognize and bind to the Y1 receptors that are significantly overexpressed on the surface of the breast cancer cells, and the drug-loaded nanoparticles are delivered directly into the cancer cells through internalization. This system is highly selective and able to distinguish the breast cancer cells from the normal cells, due to normal breast cells that express Y2 receptors only. It is anticipated that this study may provide a guidance in the development of Y1 receptor-based nanoparticulate drug delivery system for a safer and more efficient breast cancer therapy.

Abstract
We report the development of a lactobionic acid (LA)-modified multifunctional dendrimer-based carrier system for targeted therapy of liver cancer cells overexpressing asialoglycoprotein receptors. In this study, generation 5 (G5) poly(amidoamine) (PAMAM) dendrimers were sequentially modified with fluorescein isothiocyanate (FI) and LA (or polyethylene glycol (PEG)-linked LA, PEG-LA), followed by acetylation of the remaining dendrimer terminal amines. The synthesized G5.NHAc-FI-LA or G5.NHAc-FI-PEG-LA conjugates (NHAc denotes acetamide groups) were used to encapsulate a model anticancer drug doxorubicin (DOX). We show that both conjugates are able to encapsulate approximately 5.0 DOX molecules within each dendrimer and the formed dendrimer/DOX complexes are stable under different pH conditions and different aqueous media. The G5.NHAc-FI-PEG-LA conjugate appears to have a better cytocompatibility, enables a slightly faster DOX release rate, and displays better liver cancer cell targeting ability than the G5.NHAc-FI-LA conjugate without PEG under similar experimental conditions. Importantly, the developed G5.NHAc-FI-PEG-LA/DOX complexes are able to specifically inhibit the growth of the target cells with a better efficiency than the G5.NHAc-FI-LA/DOX complexes at a relatively high DOX concentration. Our results suggest a key role played by the PEG spacer that affords the dendrimer platform with enhanced targeting and therapeutic efficacy of cancer cells. The developed LA-modified multifunctional dendrimer conjugate with a PEG spacer may be used as a delivery system for targeted liver cancer therapy and offers new opportunities in the design of multifunctional drug carriers for targeted cancer therapy applications.
