Combining photothermal therapy (PTT) with clinical technology to kill cancer via overcoming the low tumor targeting and poor therapy efficiency has great potential in basic and clinical researches. A brand‐new MoS2 nanostructure is designed and fabricated, i.e., layered MoS2 hollow spheres (LMHSs) with strong absorption in near‐infrared region (NIR) and high photothermal conversion efficiency via...
In drug delivery systems, pH‐sensitive polymers are commonly used as drug carriers, and significant efforts have been devoted to the aspects of controlled delivery and release of drugs. However, few studies address the possible autophagic effects on cells. Here, for the first time, using a fluorescent autophagy‐reporting cell line, this study evaluates the autophagy‐induced capabilities of four types...
Self‐propelled Au‐BP7@SP Janus‐like nanohybrids with active motion under NIR laser can effectively enhance the temperature of tumors, potentially by converting the kinetic energy into thermal energy, enhancing photothermal tumor therapy. On page 5423, Y.‐S. Li, L. Wang, H. Wang, and co‐workers provide an insight into nanohybrids' effect on photothermal treatment and open a new avenue to cancer treatment...
Au‐BP7@SP nanohybrids with active motion under NIR laser irradiation can effectively enhance the temperature of tumor potentially by converting the kinetic energy to thermal energy, enhancing the killing efficiency of the tumor cells compared with Au@SP. The study provides an insight of nanohybrids' effect on photothermal treatment and opens a new avenue to cancer treatment by using self‐propulsion...
Amino acid‐based poly(ester amide)s are a new family of biodegradable polymers that exhibit “pseudo‐protein” characteristics and the structural varieties of poly(ester amide)s make them hold great potential in multiple biomedical applications. In this study, a lysine‐phenylalanine‐based pseudo‐protein is developed as the self‐assembled nanomicellar carrier for efficient delivery of doxorubicin. The...
Emerging nanotechnologies show unprecedented advantages in accelerating cancer theranostics. Among them, two‐dimensional nanomaterials (2DNMs) represent a novel type of material with versatile physicochemical properties that have enabled a new horizon for applications in both cancer diagnosis and therapy. Studies have demonstrated that 2DNMs may be used in diverse aspects, including i) cancer detection...
There is a pressing need to develop more effective therapeutics to fight cancer. An idyllic chemotherapeutic is expected to overcome drug resistance of tumors and minimize harmful side effects to healthy tissues. Antibody‐functionalized porous silicon nanoparticles loaded with a combination of chemotherapy drug and gold nanoclusters (AuNCs) are developed. These nanocarriers are observed to selectively...
Strategically fabricated theranostic nanocarrier delivery system is an unmet need in personalized medicine. Herein, this study reports a versatile folate receptor (FR) targeted nanoenvelope delivery system (TNEDS) fabricated with gold core silica shell followed by chitosan–folic acid conjugate surface functionalization by for precise loading of doxorubicin (Dox), resembled as Au@SiO2‐Dox‐CS‐FA. TNEDS...
Magnetic‐luminescent nanocomposites have multiple uses including multimodal imaging, magnetic targeted drug delivery, and cancer imaging‐guided therapies. In this work, dumbbell‐like MnFe2O4–NaYF4 Janus nanoparticles are synthesized via a two‐step thermolysis approach. These synthesized nanoparticles exhibit stability in aqueous solutions and very low cytotoxicity after poly(acryl amide) modification...
Short circulation time and off‐target toxicity are the main challenges faced by small‐molecule chemotherapeutics. To overcome these shortcomings, an albumin‐binding peptide conjugate of chemotherapeutics is developed that binds specifically to endogenous albumin and harnesses its favorable pharmacokinetics and pharmacodynamics for drug delivery to tumors. A protein‐G‐derived albumin‐binding domain...
In cells, mechanical forces play a key role in impacting cell behaviors, including adhesion, differentiation, migration, and death. Herein, a 20 nm mitochondria‐targeted zinc‐doped iron oxide nanocube is designed as a nanospinner to exert mechanical forces under a rotating magnetic field (RMF) at 15 Hz and 40 mT to fight against cancer. The nanospinners can efficiently target the mitochondria of cancer...
Tailoring patient‐specific treatments for cancer is necessary in order to achieve optimal results but requires new diagnostic approaches at affordable prices. Microfluidics has immense potential to provide solutions for this, as it enables the processing of samples that are not available in large quantities (e.g., cells from patient biopsies), is cost efficient, provides a high level of automation,...
Photothermal therapy (PTT) has attracted tremendous attention due to its noninvasiveness and localized treatment advantages. However, heat shock proteins (HSPs) associated self‐preservation mechanisms bestow cancer cells thermoresistance to protect them from the damage of PTT. To minimize the thermoresistance of cancer cells and improve the efficacy of PTT, an integrated on‐demand nanoplatform composed...
Probing the dynamics and quantifying the activities of intracellular protein kinases that coordinate cell growth and division and constitute biomarkers and pharmacological targets in hyperproliferative and pathological disorders remain a challenging task. Here engineering and characterization of a nanobiosensor of the mitotic kinase CDK1, through multifunctionalization of carbon nanotubes with a CDK1‐specific...
Human papilloma virus (HPV)‐16 is associated with cervical cancers and induces expression of the E6 and E7 oncogenes. Using a murine cell line that expresses these, the genes are sequenced, and six predicted major histocompatibility complex (MHC) class I (MHC‐I) epitopes are identified. A liposomal vaccine adjuvant based on cobalt–porphyrin‐phospholipid (CoPoP) is admixed with synthetic 9‐mer epitopes...
For decades, several attempts have been made to obtain a mimetic model for the study of metastasis, the reason of most of deaths caused by cancer, in order to solve the unknown phenomena surrounding this disease. To better understand this cellular dissemination process, more realistic models are needed that are capable of faithfully recreating the entire and essential tumor microenvironment (TME)...
Encapsulation of small molecule drugs in long‐circulating lipid nanoparticles (LNPs) can reduce toxic side effects and enhance accumulation at tumor sites. A fundamental problem, however, is the slow release of encapsulated drugs from these liposomal systems at the disease site resulting in limited therapeutic benefit. Methods to trigger release at specific sites are highly warranted. Here, it is...
Chemodynamic therapy (CDT), which induces cell death by decomposing high levels of H2O2 in tumor cells into highly toxic ·OH, is recognized as a promising antineoplastic approach. However, current CDT approaches are often restricted by the highly controlled and upregulated cellular antioxidant defense. To enhance ·OH‐induced cellular damage by CDT, a covalent organic framework (COF)‐based, ferrocene...
