| Open AccessEfficient electrospray deposition of surfaces smaller than the spray plume
Electrospray deposition is a promising technique for depositing functional coatings at the micro-/nano-scale. Here, the authors establish the necessary conditions for high efficiency electrospray deposition of small targets, establishing promise as an alternative to other conformal coating methods.

| Open AccessA cooperative nano-CRISPR scaffold potentiates immunotherapy via activation of tumour-intrinsic pyroptosis
Delivery of immune therapy drugs to tumours might be hampered by their limited bioavailability and the difficulty of targeting complex exogenous compounds. Here authors trigger immunologic cell death, via activating tumour-cell-intrinsic pathways via CRISPR-based nanotechnology to enable efficient anti-tumour immune response in mouse models of melanoma.

| Open AccessImmunosuppressive biomaterial-based therapeutic vaccine to treat multiple sclerosis via re-establishing immune tolerance
Multiple sclerosis is a debilitating autoimmune disease, for which therapy is not curative, only slowing down progression at the expense of general immune suppression. Here authors show that in a mouse model of multiple sclerosis, disease progression could be halted or even reversed by a nanovaccine, composed of reactive oxygen species scavenging cerium oxide nanoparticles, which establishes immune tolerance against the relevant autoantigen.

| Open AccessIn situ generation of micrometer-sized tumor cell-derived vesicles as autologous cancer vaccines for boosting systemic immune responses
Autologous tumor cell vaccines can elicit anti-tumor immune responses. Here, the authors report the design of dendritic polymer-based nanoparticles loaded with doxorubicin and the tyrosine kinase inhibitor apatinib that can induce immunogenic cell death and the in situ production of immuno-stimulatory micrometer-sized vesicles, promoting anti-tumor immune responses in preclinical models.

| Open AccessPolycarbonate-based ultra-pH sensitive nanoparticles improve therapeutic window
Stimuli-responsive nanomaterials offer the opportunity to exploit nanoscale cooperativity to improve the precision of diagnostic or therapeutic outcomes. Here, the authors report the design, synthesis and characterization of a series of degradable ultra-pH sensitive polymers that amplify small acidic pH changes to efficacious therapeutic outputs.

| Open AccessBiomaterial-based scaffold for in situ chemo-immunotherapy to treat poorly immunogenic tumors
The immunosuppressive tumour microenvironment impairs immunotherapy in poorly immunogenic cancer. Here, the authors load an alginate gel with GM-CSF, CpG oligonucleotides and doxorubicin-iRGD to promote immunogenic death of tumour cells and improve immunotherapy efficacy in triple negative breast cancer models.

| Open AccessSelf-amplifying RNA SARS-CoV-2 lipid nanoparticle vaccine candidate induces high neutralizing antibody titers in mice
Here, the authors develop a self-amplifying RNA encoding the SARS-CoV-2 spike protein encapsulated within a lipid nanoparticle as a vaccine candidate and show induction of neutralization antibody titers in mice that are comparable to titers in convalescent sera of patients.

| Open AccessHigh-throughput quantitation of inorganic nanoparticle biodistribution at the single-cell level using mass cytometry
Assessing nanomaterials at the single cell level has proven to be complicated due to the limitations of existing techniques. Here, the authors utilised single-cell mass cytometry by time-of-flight as a label-free technique to analyse nanoparticle distribution within cells.

Injectable cryogel-based whole-cell cancer vaccines
Immune responses are induced in the organized, cytokine-rich environment of lymph nodes, which can be mimicked by biomaterials. Here the authors show that injectable sponge-like gels decorated with immunostimulatory factors attract dendritic cells and boost antitumour immune responses in mice.
