Abstract
DNA nanotechnology leverages Watson-Crick-Franklin base-pairing interactions to build complex DNA-based nanostructures (DNS). Due to DNA specific self-assembly properties, DNS can be designed with a total control of their architecture, which has been demonstrated to have an impact on the overall DNS features. Indeed, structural properties such as the shape, size and flexibility of DNS can influence their biostability as well as their ability to internalise into cells. We present here two series of simple DNS with small and precise variations related to their length or flexibility and study the influence that these structural changes have on their overall properties as drug nanocarriers. Results indicate that shorter and more flexible DNS present higher stability towards nuclease degradation. These structural changes also have a certain effect on their cell internalisation ability and drug release rate. Consequently, drug-loaded DNS cytotoxicity varies according to the design, with lower cell viability values obtained in the DNS exhibiting faster drug release and larger cell interaction rates. In summary, small changes in the structure of simple DNS can have an influence on their overall capabilities as drug nanocarriers. The effects reported here could guide the design of simple DNS for future therapeutic uses.

Abstract
The development of a multifunctional cancer diagnosis and treatment platform offers excellent prospects for the effective eradication of malignant solid tumors. Herein, a doxorubicin hydrochloride (DOX)-loaded tannic acid (TA)-coated liquid metal (LM) multifunctional nanoprobe was synthesized and applied as a highly efficient platform for the photoacoustic (PA) imaging-guided photothermal/chemotherapy of tumor. The multifunctional nanoprobes exhibited strong near-infrared absorption, a remarkable photothermal conversion efficiency (PCE) of 55%, and high DOX loading capacity. Combined with the large intrinsic thermal expansion coefficient of LM, highly efficient PA imaging and effective drug release were realized. The LM-based multifunctional nanoprobes were specifically adsorbed into the cancer cells and tumor tissues via glycoengineering biorthogonal chemistry. The in vitro and in vivo photothermal/chemo-anticancer activity confirmed their promising potential in cancer treatment. The subcutaneous breast tumor-bearing mice completely recovered in 5 days under light illumination with clear PA imaging presentation, which showed better antitumor outcomes than single-mode chemotherapy or photothermal therapy (PTT), while keeping side effects at a minimum. Such an LM-based PA imaging-guided photothermal/chemotherapy strategy provided a valuable platform for resistant cancer precise treatment and intelligent biomedicine.

Abstract
A longstanding problem with conventional cancer therapy is the nonspecific distribution of chemotherapeutics. Monitoring drug release in vivo via noninvasive bioimaging can thus have value, but it is difficult to distinguish loaded from released drug in live tissue. Here, this work describes an injectable supramolecular hydrogel that allows slow and trackable release of doxorubicin (Dox) via photoacoustic (PA) tomography. Dox is covalently linked with photoacoustic methylene blue (MB) to monitor Dox before, during, and after release from the hydrogel carrier. The conjugate (MB-Dox) possesses an IC50 of 161.4 × 10-9 m against human ovarian carcinoma (SKOV3) cells and loads into a DNA-clad hydrogel with 91.3% loading efficiency due to MB-Dox's inherent intramolecular affinity to DNA. The hydrogel is biodegradable by nuclease digestion, which causes gradual release of MB-Dox. This release rate is tunable based on the wt% of the hydrogel. This hydrogel maintains distinct PA contrast on the order of days when injected in vivo and demonstrates activatable PA spectral shifts during hydrogel degradation. The released and loaded payload can be imaged relative to live tissue via PA and ultrasound signal being overlaid in real-time. The hydrogel slowed the rate of the murine intraperitoneal tumor growth 72.2% more than free Dox.

Abstract
![]()
The design of simple and versatile synthetic routes to
accomplish
triggered-release properties in carriers is of particular interest
for drug delivery purposes. In this context, the programmability and
adaptability of DNA nanoarchitectures in combination with liposomes
have great potential to render biocompatible hybrid carriers for triggered
cargo release. We present an approach to form a DNA mesh on large
unilamellar liposomes incorporating a stimuli-responsive DNA building
block. Upon incubation with a single-stranded DNA trigger sequence,
a hairpin closes, and the DNA building block is allowed to self-contract.
We demonstrate the actuation of this building block by single-molecule
Förster resonance energy transfer (FRET), fluorescence recovery
after photobleaching, and fluorescence quenching measurements. By
triggering this process, we demonstrate the elevated release of the
dye calcein from the DNA–liposome hybrid carriers. Interestingly,
the incubation of the doxorubicin-laden active hybrid carrier with
HEK293T cells suggests increased cytotoxicity relative to a control
carrier without the triggered-release mechanism. In the future, the
trigger could be provided by peritumoral nucleic acid sequences and
lead to site-selective release of encapsulated chemotherapeutics.

Abstract
Optoacoustic (photoacoustic) imaging has demonstrated versatile applications in biomedical research, visualizing the disease pathophysiology and monitoring the treatment effect in an animal model, as well as toward applications in the clinical setting. Given the complex disease mechanism, multimodal imaging provides important etiological insights with different molecular, structural, and functional readouts in vivo. Various multimodal optoacoustic molecular imaging approaches have been applied in preclinical brain imaging studies, including optoacoustic/fluorescence imaging, optoacoustic imaging/magnetic resonance imaging (MRI), optoacoustic imaging/MRI/Raman, optoacoustic imaging/positron emission tomography, and optoacoustic/computed tomography. There is a rapid development in molecular imaging contrast agents employing a multimodal imaging strategy for pathological targets involved in brain diseases. Many chemical dyes for optoacoustic imaging have fluorescence properties and have been applied in hybrid optoacoustic/fluorescence imaging. Nanoparticles are widely used as hybrid contrast agents for their capability to incorporate different imaging components, tunable spectrum, and photostability. In this review, we summarize contrast agents including chemical dyes and nanoparticles applied in multimodal optoacoustic brain imaging integrated with other modalities in small animals, and provide outlook for further research.
