Surgical resection is the primary and most effective treatment for most patients with solid tumors. However, patients suffer from postoperative recurrence and metastasis. In the past years, emerging nanotechnology has led the way to minimally invasive, precision and intelligent oncological surgery after the rapid development of minimally invasive surgical technology. Advanced nanotechnology in the construction of nanomaterials (NMs) for precision imaging-guided surgery (IGS) as well as surgery-assisted synergistic therapy is summarized, thereby unlocking the advantages of nanotechnology in multimodal IGS-assisted precision synergistic cancer therapy. First, mechanisms and principles of NMs to surgical targets are briefly introduced. Multimodal imaging based on molecular imaging technologies provides a practical method to achieve intraoperative visualization with high resolution and deep tissue penetration. Moreover, multifunctional NMs synergize surgery with adjuvant therapy (e.g., chemotherapy, immunotherapy, phototherapy) to eliminate residual lesions. Finally, key issues in the development of ideal theranostic NMs associated with surgical applications and challenges of clinical transformation are discussed to push forward further development of NMs for multimodal IGS-assisted precision synergistic cancer therapy.

As a cutting-edge imaging technology, fluorescence imaging in the second near-infrared (NIR-II, 1000-1700 nm) window has attracted tremendous attention. Compared to the classical fluorescence imaging in the visible (400-650 nm) and NIR-I (650-950 nm) window, the NIR-II fluorescence imaging greatly improves photon penetration in living bodies with high fidelity due to its minimized tissue absorption, scattering, and autofluorescence. It is considered to be the next-generation intravital fluorescence imaging technique which has great potential for biomedical research and clinical practice. Herein, the progress of NIR-II fluorescence imaging in tumor theranostics is summarized. The recent advances in tumor diagnosis and therapeutic evaluation using this novel imaging technique are highlighted, and its current challenges and future perspectives are discussed.Fluorescence imaging technology opens a new era of biomedical research, which provides a straightforward visible approach

“…By contrast, positron emission tomography (PET) with virtually unlimited tissue penetrating depth, high sensitivity, and quantitative effect can eliminate the above defects of NIR‐II imaging in tumor diagnosis and therapy . However, PET suffers from its own drawbacks such as low spatial revolution, time consuming process, and difficulty for application in intraoperative guidance . These drawbacks of PET seem likely to be overcome by NIR‐II imaging.…”

Bimodal imaging with fluorescence in the second near infrared window (NIR‐II) and positron emission tomography (PET) has important significance for tumor diagnosis and management because of complementary advantages. It remains challenging to develop NIR‐II/PET bimodal probes with high fluorescent brightness. Herein, bioinspired nanomaterials (melanin dot, mesoporous silica nanoparticle, and supported lipid bilayer), NIR‐II dye CH‐4T, and PET radionuclide 64Cu are integrated into a hybrid NIR‐II/PET bimodal nanoprobe. The resultant nanoprobe exhibits attractive properties such as highly uniform tunable size, effective payload encapsulation, high stability, dispersibility, and biocompatibility. Interestingly, the incorporation of CH‐4T into the nanoparticle leads to 4.27‐fold fluorescence enhancement, resulting in brighter NIR‐II imaging for phantoms in vitro and in situ. Benefiting from the fluorescence enhancement, NIR‐II imaging with the nanoprobe is carried out to precisely delineate and resect tumors. Additionally, the nanoprobe is successfully applied in tumor PET imaging, showing the accumulation of the nanoprobe in a tumor with a clear contrast from 2 to 24 h postinjection. Overall, this hierarchically nanostructured platform is able to dramatically enhance fluorescent brightness of NIR‐II dye, detect tumors with NIR‐II/PET imaging, and guide intraoperative resection. The NIR‐II/PET bimodal nanoprobe has high potential for sensitive preoperative tumor diagnosis and precise intraoperative image‐guided surgery.
