Abstract
Ultrasound has been broadly used in biomedicine for both tumor diagnosis as well as therapy. The applications of recent developments in micro/nanotechnology promote the development of ultrasound-based biomedicine, especially in the field of ultrasound-based drug delivery and tumor therapy. Ultrasound can activate nano-sized drug delivery systems by different mechanisms for ultrasound- triggered on-demand drug release targeted only at the tumor sites. Ultrasound Targeted Microbubble Destruction (UTMD) technology can not only increase the permeability of vasculature and cell membrane via sonoporation effect but also achieve in situ conversion of microbubbles into nanoparticles to promote cellular uptake and therapeutic efficacy. Furthermore, High Intensity Focused Ultrasound (HIFU), or Sonodynamic Therapy (SDT), is considered to be one of the most promising and representative non-invasive treatment for cancer. However, their application in the treatment process is still limited due to their critical treatment efficiency issues. Fortunately, recently developed micro/nanotechnology offer an opportunity to solve these problems, thus improving the therapeutic effect of cancer. This review summarizes and discusses the recent developments in the design of micro- and nano- materials for ultrasound-based biomedicine applications.

Abstract
This minireview highlights the recent advances in the therapeutic agents that aim to provide synergistic enhancements of focused ultrasound treatment of tumors. Even though focused ultrasound therapy itself can bring therapeutic effects in cancers, many biochemical agents have been reported in the literature to enhance the treatment efficacy significantly. Until now, many mechanisms have been researched to advance the therapy, such as sonodynamic-plus-chemo-therapy, microbubble-aided therapy, localized release or delivery of nanomaterials, and multimodal image-guided therapy. Here, the novel materials adopted in each mechanism are briefly reviewed to provide a trend in the field and encourage future research towards the successful deployment of focused ultrasound therapy in real clinical environments.

Abstract
Nanoscale systems have increasingly been used in biomedical applications, enhancing the demand for the development of biomolecule-functionalized nanoparticles for targeted applications. Such designer nanosystems hold great prospective to refine disease diagnosis and treatment. To completely investigate their potential for bioapplications, nanoparticles must be biocompatible and targetable toward explicit receptors to guarantee particular detecting, imaging, and medication conveyance in complex organic milieus, for example, living cells, tissues, and organisms. We present recent works that explore enhanced biocompatibility and biorecognition of nanoparticles functionalized with DNA and different DNA entities such as aptamers, DNAzymes, and aptazymes. We sum up the methods utilized in the amalgamation of complex nanostructures, survey the significant types of multifunctional nanoparticles that have been developed in the course of recent years, and give a perceptual vision of the significant field of nanomedicine. The field of DNA-functionalized nanoparticles holds an incredible guarantee in rising biomedical zones, for example, multimodal imaging, theranostics, and picture-guided treatments.

Abstract
Ultrasound (US)-responsive carriers have emerged as promising theranostic candidates because of their ability to enhance US-contrast, promote image-guided drug delivery, cause on-demand pulsatile release of drugs in response to ultrasound stimuli, as well as to enhance the permeability of physiological barriers such as the stratum corneum, the vascular endothelium, and the blood-brain barrier (BBB). US-responsive carriers include microbubbles MBs, liposomes, droplets, hydrogels, and nanobubble-nanoparticle complexes and have been explored for cavitation-mediated US-responsive drug delivery. Recently, a transient increase in the permeability of the BBB by microbubble (MB)-assisted low-frequency US has shown promise in enhancing the delivery of therapeutic agents in the case of neurological disorders. Further, the periodic mechanical stimulus generated by US-responsive MBs have also been explored in tissue engineering and has directly influenced the differentiation of mesenchymal stem cells into cartilage. This Review discusses the various types of US-responsive carriers and explores their emerging roles in therapeutics ranging from drug delivery to tissue engineering.

Abstract
The therapeutic effect of small hydrophilic molecules is limited by the rapid clearance from the systemic circulation or a local site of administration. The unsuitable pharmacokinetics and biodistribution can be improved by encapsulating them in drug delivery systems. However, the high-water solubility, very hydrophilic nature, and low molecular weight make it difficult to encapsulate small hydrophilic molecules in many drug delivery systems. In this mini-review, we highlight three strategies to efficiently encapsulate small hydrophilic molecules and achieve controlled release: physical encapsulation in micro/nanocapsules, physical adsorption via electronic interactions, and covalent conjugation. The principles, advantages, and disadvantages of each strategy are discussed. This review paper could be a guide for scientists, engineers, and medical doctors who want to improve the therapeutic efficacy of small hydrophilic drugs.

Abstract
Modalities for photo-triggered anticancer therapy are usually limited by their low penetrative depth. Sonotheranostics especially sonodynamic therapy (SDT), which is different from photodynamic therapy (PDT) by the use of highly penetrating acoustic waves to activate a class of sound-responsive materials called sonosensitizers, has gained significant interest in recent years. The effect of SDT is closely related to the structural and physicochemical properties of the sonosensitizers, which has led to the development of new sound-activated materials as sonosensitizers for various biomedical applications. This Review provides a summary and discussion of the types of novel sonosensitizers developed in the last few years and outlines their specific designs and the potential challenges. The applications of sonosensitizers with various functions such as for imaging and drug delivery as well as in combination with other treatment modalities would provide new strategies for disease therapy.

Abstract
An on-demand anesthetic that would only take effect when needed and where the intensity of anesthesia could be easily adjustable according to patients' needs would be highly desirable. Here, we design and synthesize a macromolecular prodrug (P407-CM-T) in which the local anesthetic tetracaine (T) is attached to the polymer poloxamer 407 (P407) via a photo-cleavable coumarin linkage (CM). P407-CM-T solution is an injectable liquid at room temperature and gels near body temperature. The macromolecular prodrug has no anesthetic effect itself unless irradiated with a low-power blue light emitting diode (LED), resulting in local anesthesia. By adjusting the intensity and duration of irradiation, the anesthetic effect can be modulated. Local anesthesia can be repeatedly triggered.

Abstract
With the growing demand for personalized medicine and medical devices, the impact of on-demand triggerable (e.g., via magnetic fields) drug delivery systems increased significantly in recent years. The three-dimensional (3D) printing technology has already been applied in the development of personalized dosage forms because of its high-precision and accurate manufacturing ability. In this study, a novel magnetically triggerable drug delivery device composed of a magnetic polydimethylsiloxane (PDMS) sponge cylinder and a 3D printed reservoir was designed, fabricated and characterized. This system can realize a switch between "on" and "off" state easily through the application of different magnetic fields and from different directions. Active and repeatable control of the localized drug release could be achieved by the utilization of magnetic fields to this device due to the shrinking extent of the macro-porous magnetic sponge inside. The switching "on" state of drug-releasing could be realized by the magnetic bar contacted with the side part of the device because the times at which 50%, 80% and 90% (w/w) of the drug were dissolved are observed to be 20, 55 and 140 min, respectively. In contrast, the switching "off" state of drug-releasing could be realized by the magnetic bar placed at the bottom of the device as only 10% (w/w) of the drug could be released within 12 h. An anti-cancer substance, 5-fluorouracil (FLU), was used as the model drug to illustrate the drug release behaviour of the device under different strengths of magnetic fields applied. In vitro cell culture studies also demonstrated that the stronger the magnetic field applied, the higher the drug release from the deformed PDMS sponge cylinder and thus more obvious inhibition effects on Trex cell growth. All results confirmed that the device can provide a safe, long-term, triggerable and reutilizable way for localized disease treatment such as cancer.

Abstract
The effect of local anesthetics, particularly those which are hydrophilic, such as tetrodotoxin, is impeded by tissue barriers that restrict access to individual nerve cells. Methods of enhancing penetration of tetrodotoxin into nerve include co-administration with chemical permeation enhancers, nanoencapsulation, and insonation with very low acoustic intensity ultrasound and microbubbles. In this study, we examined the effect of acoustic intensity on nerve block by tetrodotoxin and compared it to the effect on nerve block by bupivacaine, a more hydrophobic local anesthetic. Anesthetics were applied in peripheral nerve blockade in adult Sprague-Dawley rats. Insonation with 1-MHz ultrasound at acoustic intensity greater than 0.5 W/cm2 improved nerve block effectiveness, increased nerve block reliability, and prolonged both sensory and motor nerve blockade mediated by the hydrophilic ultra-potent local anesthetic, tetrodotoxin. These effects were not enhanced by microbubbles. There was minimal or no tissue injury from ultrasound treatment. Insonation did not enhance nerve block from bupivacaine. Using an in vivo model system of local anesthetic delivery, we studied the effect of acoustic intensity on insonation-mediated drug delivery of local anesthetics to the peripheral nerve. We found that insonation alone (at intensities greater than 0.5 W/cm2) enhanced nerve blockade mediated by the hydrophilic ultra-potent local anesthetic, tetrodotoxin. Graphical abstract.

Abstract
Sonodynamic therapy (SDT) has the advantages of high penetration, non-invasiveness, and controllability, and it is suitable for deep-seated tumors. However, there is still a lack of effective sonosensitizers with high sensitivity, safety, and penetration. Now, ultrasound (US) and glutathione (GSH) dual responsive vesicles of Janus Au-MnO nanoparticles (JNPs) were coated with PEG and a ROS-sensitive polymer. Upon US irradiation, the vesicles were disassembled into small Janus Au-MnO nanoparticles (NPs) with promoted penetration ability. Subsequently, GSH-triggered MnO degradation simultaneously released smaller Au NPs as numerous cavitation nucleation sites and Mn2+ for chemodynamic therapy (CDT), resulting in enhanced reactive oxygen species (ROS) generation. This also allowed dual-modality photoacoustic imaging in the second near-infrared (NIR) window and T1 -MR imaging due to the released Mn2+ , and inhibited orthotopic liver tumor growth via synergistic SDT/CDT.

Abstract
Photoacoustic (PA) imaging based on the photon-to-ultrasound conversion allows the imaging of optical absorbers in deep tissues with high spatial resolution. However, the inherent optical absorbance of biomolecules (e.g., hemoglobin, melanin, etc.) would show up as tissue background signals to interfere with signals from the contrast agent during in vivo PA imaging, limiting the imaging sensitivity. Herein, an ultrasound (US)-responsive PA imaging probe based on microbubbles (MBs) containing gold nanoparticles (Au NPs) is designed for in vivo "background-free" PA imaging. The obtained Au@lip MBs with separated Au NPs decorated within the lipid shell of MBs show low PA signals under near-infrared (NIR) excitation. Interestingly, under exposure to US pulses, those Au@lip MBs would burst to form nanoscale aggregates of Au@lip NPs, which exhibit significantly enhanced NIR PA signals due to their red-shifted surface plasmon resonance. Therefore, by subtracting the PA image captured pre-US burst from that captured post-US burst, the tissue background PA signals could be deducted to enable background-free PA imaging with high sensitivities as demonstrated by multiple ex vivo and in vivo experiments. This work presents a simple yet effective strategy to deduct background signals during PA imaging, which is promising for accurate PA detection of targets in tissues with a strong background.

Abstract
Nanoparticles (NPs) have enormous potential to improve disease diagnosis and treatment due to their intrinsic electronic, optical, magnetic, mechanical, and physiological properties. To realize their full potential for nanomedicine, NPs must be biocompatible and targetable toward specific biomolecules to ensure selective sensing, imaging, and drug delivery in complex environments such as living cells, tissues, animals, and human bodies. In this Account, we summarize our efforts to impart specific biocompatibility and biorecognition functionality to NPs by developing strategies to integrate inorganic and organic NPs with functional DNA (fDNA), including aptamers, DNAzymes, and aptazymes to create fDNA-NPs. These hybrid NPs take advantage of fDNA's ability to either bind targets or catalyze reactions in the presence of targets selectively and utilize their unique physicochemical properties including small size, low immunogenicity, and ease of synthesis and chemical modification in comparison with other molecules such as antibodies. By integrating inorganic NPs such as gold NPs, quantum dots, and iron oxide nanoparticles with fDNA, we designed stimuli-responsive fDNA-NPs that exhibit target induced assembly and disassembly of NPs, resulting in a variety of colorimetric, fluorescent, and magnetic resonance imaging (MRI)-based sensors for diagnostic of a broad range of analytes. To impart both biocompatibility and selectivity on inorganic NPs for targeted bioimaging, we have demonstrated DNA-mediated surface functionalization, shape-controlled synthesis, and coordinative assembly of such NPs as specific bioprobes. A highlight is provided on the construction of fDNA-based nanoprobes with light-activatable sensing and imaging functions, which provides precise control of recognition properties of fDNA with high spatiotemporal resolution. To explore the potential of organic NPs for biosensing applications, we have developed an enzyme-responsive fDNA-liposome as a universal sensing platform compatible with diverse biological targets as well as different detection methods including fluorescence, MRI, or temperature, making possible point-of-care diagnostics. To expand the application regime of organic NPs, we collaborated with the Zimmerman group to prepare single-chain block copolymer-based NPs and incorporated it with a variety of functions, including monovalent DNA for assembly, tunable surface chemistry for cellular imaging, and coordinative Cu(II) sites for catalyzing intracellular click reactions, demonstrating the potential of using organic NPs to create promising fDNA-NP systems with programmable functionalities. Furthermore, we survey our recent endeavor in integration of cell-specific aptamers with different NPs for targeted drug delivery, showing that introducing stimuli-responsive properties into NPs that target tumor microenvironments would enable safer and more effective therapy for cancers. Finally, current challenges and future perspectives in fDNA-mediated engineering of NPs for biomedical applications are discussed.

Abstract
Sonodynamic therapy (SDT) which employs ultrasound-triggered sonosensitizers to generate reactive oxygen species (ROS) has been proved to be effective for treatment of cancers. However, it is still desirable for sonosensitizers to be delivered to tumors as effectively as possible. In this study, we prepared the hematoporphyrin monomethyl ether (HMME)-loaded liposome as the sonosensitizers for SDT and evaluated their effects on human MCF-7 breast cancer cells in vitro and in vivo. Liposomes prepared by thin film hydration technique were about 100 nm in size with positive zeta potential and exhibited spherical in shape. Following irradiation of ultrasound which generates intracellular ROS, the liposome facilitated the delivery of HMME to tumor cells. HMME-loaded liposomes showed low cytotoxicity under basal condition but significant sonodynamic effects under ultrasonic irradiation. Notably, HMME-loaded liposomes exhibited spatial distribution of HMME in tumor tissues of mice. The promoted delivery of HMME into the tumors by liposomes was shown by the greater tumor growth inhibition than free HMME after 20-day treatment. Taken together, these results show that HMME-loaded liposome functions as a promising sonosensitizer for SDT, implying the efficient antitumor effects of HMME-based SDT on breast tumor.

Abstract
Local anesthetics have been extensively employed to treat postoperative pain, but they generally suffer from short acting duration and potential neurotoxicity under high local concentrations, which require the controlled and sustained releasing patterns of treatment drugs. In this work, it is reported, for the first time, the construction of hollow mesoporous organosilica nanoparticles (HMONs)-based nanoplatforms for localized delivery and controlled/sustained release of loaded ropivacaine for local anesthetics, which can be repeatedly triggered by either external ultrasound irradiation or acidity triggering to release the payload, causing on-demand and long-lasting analgesia. Based on the in vivo mouse model of incision pain, the controlled and sustained release of ropivacaine achieves more than six hours of continuous analgesia, which is almost three times longer as compared to single free ropivacaine injection. The low neurotoxicity and high biocompatibility of HMONs for nanoparticle-enabled analgesia are also demonstrated both in vitro and in vivo. This designed/constructed HMONs-based nanoplatform provides a potential methodology for clinical pain management via on-demand and long-lasting pain relief.

Abstract
Chemotherapy has been the most widely used treatment against cancer, however, it is limited by its systemic toxicity as well as resistance developed by tumors' physical barriers. Herein, we propose a novel acoustically-mediated treatment regime to on-demand release therapeutics and disrupt tumor structures. By programming a high intensity focused ultrasound transducer, we can locally and digitally release gemcitabine (GEM) as well as open the local blood-tumor barrier or even tumor stroma to enhance intratumor drug delivery via acoustically-oscillating bubbles and liposomes. In our experiments, we modeled tumor endothelium by culturing a monolayer of murine endothelial cells (2H11) on transwell membrane. We locally disrupted the cultured endothelium to enhance drug penetration by using perfluorocarbon liquid droplets as breaking probes and protoporphyrin IX hybridized liposomes as drug carriers. We also demonstrated an on-demand release of GEM by digitally triggering the break of drug carriers. Moreover, we validated the acoustic tumor endothelium disruption in vivo by monitoring penetration of dye (Evans blue) in solid tumors. Therefore, we present an acoustically-mediated delivery method that both releases drug on-demand locally and opens the blood-tumor barrier to enhance drug penetration. This sets the ground for further clinical cancer therapy to improve many systemic cancer treatments.

Abstract
Catheter-based intra-arterial drug therapies have proven effective for a range of oncologic, neurologic, and cardiovascular applications. However, these procedures are limited by their invasiveness and relatively broad drug spatial distribution. The ideal technique for local pharmacotherapy would be noninvasive and would flexibly deliver a given drug to any region of the body with high spatial and temporal precision. Combining polymeric perfluorocarbon nanoemulsions with existent clinical focused ultrasound systems could in principle meet these needs, but it has not been clear whether these nanoparticles could provide the necessary drug loading, stability, and generalizability across a range of drugs, beyond a few niche applications. Here, we develop polymeric perfluorocarbon nanoemulsions into a generalized platform for ultrasound-targeted delivery of hydrophobic drugs with high potential for clinical translation. We demonstrate that a wide variety of drugs may be effectively uncaged with ultrasound using these nanoparticles, with drug loading increasing with hydrophobicity. We also set the stage for clinical translation by delineating production protocols that are scalable and yield sterile, stable, and optimized ultrasound-activated drug-loaded nanoemulsions. Finally, we exhibit a new potential application of these nanoemulsions for local control of vascular tone. This work establishes the power of polymeric perfluorocarbon nanoemulsions as a clinically-translatable platform for efficacious, noninvasive, and localized ultrasonic drug uncaging for myriad targets in the brain and body.

Abstract
Nanotechnology, which has already revolutionised many technological areas, is expected to transform life sciences. In this sense, nanomedicine could address some of the most important limitations of conventional medicine. In general, nanomedicine includes three major objectives: (1) trap and protect a great amount of therapeutic agents; (2) carry them to the specific site of disease avoiding any leakage; and (3) release on-demand high local concentrations of therapeutic agents. This feature article will make special emphasis on mesoporous silica nanoparticles that release their therapeutic cargo in response to ultrasound.

Abstract
Intravenous regional anesthesia (IVRA; Bier block) is commonly used to anesthetize an extremity for surgery. Limitations of the procedure include pain from the required tourniquet, the toxicity that can occur from systemic release of local anesthetics, and the lack of postoperative pain relief. We hypothesized that the nanoencapsulation of the local anesthetic would prolong local anesthesia and enhance safety. Here, we developed an ∼15 nm micellar bupivacaine formulation (M-Bup) and tested it in a rat tail vein IVRA model, in which active agents were restricted in the tail by a tourniquet for 15 min. After tourniquet removal, M-Bup provided local anesthesia for 4.5 h, which was two times longer than that from a larger dose of free bupivacaine. Approximately 100 nm liposomal bupivacaine (L-Bup) with the same drug dose as M-Bup did not cause anesthesia. Blood levels of bupivacaine after tourniquet removal were lower in animals receiving M-Bup than L-Bup or free bupivacaine, demonstrating enhanced safety. Tissue reaction to M-Bup was benign.

Abstract
Delivery of compounds to the peripheral nervous system has the potential to be used as a treatment for a broad range of conditions and applications, including neuropathic pain, regional anesthesia, traumatic nerve injury, and inherited and inflammatory neuropathies. However, efficient delivery of therapeutic doses can be difficult to achieve due to peripheral neuroanatomy and the restrictiveness of the blood-nerve barrier. Depending on the underlying integrity of the blood-nerve barrier in the application at hand, several strategies can be employed to navigate the peripheral nerve architecture and facilitate targeted delivery to the peripheral nerve. This review describes different applications where targeted delivery to the peripheral nervous system is desired, the challenges that the blood-nerve barrier poses in each application, and bioengineering strategies that can facilitate delivery in each application.

Abstract
Alzheimer's disease (AD) has become one of the most serious societal problems globally, with no effective treatments. Parenchymal accumulation of amyloid beta (Aβ) plaques and the formation of neurofibrillary tangles are the hallmarks of AD. Their possible interactions and synergistic effects in AD have been gradually elucidated. The failure of many clinical trials suggests that it is difficult to treat AD with a focus on a single target. Instead, multiple targets may be an important direction for AD drug research. In this study, we used protoporphyrin IX (PX)-modified oxidized mesoporous carbon nanospheres (OMCN) (PX@OMCN@PEG(OP)@RVGs) as a novel AD multifunctional nanodrug having multiple targets. The nanodrug efficiently inhibits tau phosphorylation. In addition, the use of PX with focused ultrasound triggered the production of reactive oxygen species that significantly inhibited Aβ aggregation. Both approaches notably increased the cognitive level of APP/PS1 transgenic (Tg) mice and ultimately achieved dual-target inhibition of AD. Furthermore, the safe and effective delivery of PX across the blood-brain barrier (BBB) due to modification of the RVG peptide was demonstrated in vivo and in vitro. The favorable photothermal effect of the nanoparticles improved the BBB permeability of PX@OP@RVGs under near-infrared irradiation. The results demonstrated that the novel PX@OP@RVG multifunctional nanomedicine has a dual-target treatment capability for AD and can traverse the BBB, indicating the potential for the effective treatment of AD.

Enhanced drug delivery using sonoactivatable liposomes with membrane-embedded porphyrins. J Control Release 2018; 286:358-368. [PMID: 30075210 DOI: 10.1016/j.jconrel.2018.07.048] [Citation(s) in RCA: 55] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Revised: 07/06/2018] [Accepted: 07/31/2018] [Indexed: 01/10/2023]
Abstract
Small molecules that interfere with nucleic acid are widely used in chemotherapy, however, improved delivery approaches are required to improve anti-tumor outcomes. Here, we present the development of an ultrasound-activatable porphyrin-phospholipid-liposome (pp-lipo) that responds to low intensity focused ultrasound (LIFU) for sonodynamic therapy (SDT). The pp-lipo is constructed by incorporating a small proportion of porphyrin (pyropheophorbide) conjugated lipid into a liposome formulation. This enables sonosensitization-induced lipid oxidation and efficient disruption of liposomes to release loaded doxorubicin (Dox). This results in increased Dox nuclear subcellular location and cytotoxicity in cancer cells in vitro upon pp-lipo exposure to LIFU. Following intravenous administration, LIFU enhanced deposition of Dox within tumor tissue, suppressed tumor growth, and also increased porphyrin near infrared tumor fluorescence. Thus, pp-lipo is a versatile carrier that can be extended to many ultrasound-controllable drug delivery applications.

Predicting the tissue depth for remote triggering of drug delivery systems. J Control Release 2018; 286:55-63. [PMID: 30030183 DOI: 10.1016/j.jconrel.2018.07.033] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2018] [Revised: 07/12/2018] [Accepted: 07/16/2018] [Indexed: 11/23/2022]
Abstract
Externally triggerable drug delivery systems have promising potential in providing flexible control of the timing, duration, and intensity of treatment according to patient's needs, while reducing side effects and increasing therapeutic efficacy. However, a limitation to translating such systems into clinical practice is the difficulty to predict the tissue depth at which such systems could be safely used in vivo (e.g. activatable at the target site with a clinically-safe energy dosage). An effective method is needed to evaluate the clinical potential of externally triggerable drug delivery systems. Here we have a method and approach to predicting the tissue depth at which a drug delivery system can be safely triggered in vivo by an external energy source. We used in vitro and ex vivo experiments combined with a mathematical model to develop a method to predict activated drug release at different tissue depths, which was then validated in vivo. We constructed these models for liposomal drug delivery systems triggered by two of the most commonly studied external stimuli: ultrasound and near infrared light. We developed the approach in two prevalent tissue types: muscle and fat. Our method identified two important parameters in the activation of drug delivery systems in tissue: 1) the ability of the activating energy to penetrate tissue, 2) the sensitivity of the system to the activation source. The method was validated by correlation with triggered sciatic nerve block in the rat in vivo, demonstrating that this approach provided an accurate estimate of activated release at different tissue depths.

Abstract
Management of postoperative pain following bone surgery includes administration of local anesthetics (LAs). Smart delivery systems, including triggered systems, have been designed to provide a continuous release of LA in situ. However, these systems can provide a high level of LA locally. This review will examine the state-of-the-art regarding the LA delivery systems optimized for management of postoperative pain in bone surgery and will discuss the potential adverse effects of LAs on the overall pathways of bone healing, including the inflammation response phase, hemostasis phase, tissue repair phase and remodeling phase. There is a clinical need to document these effects and the potential impacts on the clinical outcome of the patient.

Abstract
In this study, we present an innovation in the tumor treatment in vivo mediated by magnetic mesoporous silica nanoparticles. This device was built with iron oxide magnetic nanoparticles embedded in a mesoporous silica matrix and coated with an engineered thermoresponsive polymer. The magnetic nanoparticles act as internal heating sources under an alternating magnetic field (AMF) that increase the temperature of the surroundings, provoking the polymer transition and consequently the release of a drug trapped inside the silica pores. By a synergic effect between the intracellular hyperthermia and chemotherapy triggered by AMF application, significant tumor growth inhibition was achieved in 48 h after treatment. Furthermore, the small magnetic loading used in the experiments indicates that the treatment is carried out without a global temperature rise of the tissue, which avoids the problem of the necessity to employ large amounts of magnetic cores, as is common in current magnetic hyperthermia.

Abstract
Background Tamoxifen is the standard endocrine therapy for breast cancers, which require metabolic activation by cytochrome P450 enzymes (CYP). However, the lower and variable concentrations of CYP activity at the tumor remain major bottlenecks for the efficient treatment, causing severe side-effects. Combination nanotherapy has gained much recent attention for cancer treatment as it reduces the drug-associated toxicity without affecting the therapeutic response. Results Here we show the modular design of P22 bacteriophage virus-like particles for nanoscale integration of virus-driven enzyme prodrug therapy and photodynamic therapy. These virus capsids carrying CYP activity at the core are decorated with photosensitizer and targeting moiety at the surface for effective combinatory treatment. The estradiol-functionalized nanoparticles are recognized and internalized into ER+ breast tumor cells increasing the intracellular CYP activity and showing the ability to produce reactive oxygen species (ROS) upon UV365 nm irradiation. The generated ROS in synergy with enzymatic activity drastically enhanced the tamoxifen sensitivity in vitro, strongly inhibiting tumor cells. Conclusions This work clearly demonstrated that the targeted combinatory treatment using multifunctional biocatalytic P22 represents the effective nanotherapeutics for ER+ breast cancer.

Abstract
I propose two-dimensional simulations of drug release from a liposome into the bloodstream. I perform the fluid-structure coupling, between the particles deformation (the liposome and the red blood cells) and the plasma flow, using the immersed boundary method. I compute both the flow and the drug mass transport using the lattice Boltzmann method. The simulations allow computing the instantaneous amount of the released drug, its distribution and its accumulation in the blood vessel wall. These quantities are sensitive to multiple factors and parameters. Here, I briefly explore the impact of having surrounding red blood cells, which are found to enhance slightly the drug release at large Schmidt numbers. In the limit of extremely large permeability of the particles, the drug transport is mainly affected by the complex flow induced by the interplay between the applied flow and the collective motion of the particles.

Abstract
Despite extensive efforts in recent years, the blood-brain barrier (BBB) remains a significant obstacle for drug delivery. This study proposes using a clinical extracorporeal shockwave instrument to open the BBB, combined with a laser assisted bi-axial locating platform to achieve non-invasive, controllable-focus and reversible BBB opening in the brains of rats. Under shockwave treatment with an intensity level of 5 (P-9.79 MPa, energy flux density (EFD) 0.21 mJ/mm2) and a pulse repetition frequency of 5 Hz, the BBB could be opened after 50 shocks without the use of an ultrasound contrast agent. With the proposed method, the BBB opening can be precisely controlled in terms of depth, size and location. Moreover, a shockwave based gene transfection was demonstrated using a luciferase gene.

Abstract
On-demand pain relief systems would be very helpful additions to the armamentarium of pain management. Near-infrared triggered drug delivery systems have demonstrated the potential to provide such care. However, challenges remain in making such systems as stimulus-sensitive as possible, to enhance depth of tissue penetration, repeatability of triggering, and safety. Here we developed liposomes containing the local anesthetic tetrodotoxin and also containing a photosensitizer and gold nanorods that were excitable at the same near-infrared wavelength. The combination of triggering mechanisms enhanced the photosensitivity and repeatability of the system in vitro when compared with liposomes with a single photoresponsive component. In vivo, on-demand local anesthesia could be induced with a low irradiance and short irradiation duration, and liposomes containing both photosensitizer and gold nanorods were more effective than those containing just one photoresponsive component. Tissue reaction was benign.
