  1. Chiappini, E. DeRosa, J.O. Martinez, X. Liu, J. Steele, M. Stevens, E. Tasciotti, Biodegradable silicon nanoneedles delivering nucleic acids intracellularly induce localized in vivo neovascularization, Nature Materials 14, 532-539 (2015).[Cover Article].
    Summary: This work is the first use of nanoneedles for tissue engineering, and the first use of nanoneedles in vivo. It first attempts in vivo gene therapy with nanoneedles demonstrating a functional outcome, and thus providing a conceptual advancement towards their clinical translation. It demonstrates biodegradable nanoneedles as a versatile intracellular delivery platform in vivo, characterized by ease of use and a simple application strategy. It highlights the promise of this technology to address the clinical need associated with the transfer of biologically labile compounds such as nucleic acids through a minimally invasive procedure, and it opens the possibility of studying cell reprogramming in vivo through gene transfer to defined tissue regions.

    Summary: This work represents the first use of nanoneedles for cancer detection and their first use with clinical samples. It proposes the first nanoneedle-based strategy that achieves sensing with single cell resolution highlighting a promising technology for minimally invasive intracellular quantification of enzymatic activity both in vitro and in vivo. This technology can be developed to address the clinical need for screening patients and providing guidance for further, more invasive diagnostics such as biopsies. The potential to map the intracellular milieu in vivo with minimal impact could lead to new materials for direct cell manipulation as well as improve rapid screening and stratification of patients in the context of chronic and degenerative diseases.

    Summary: This work is the first investigation of the temporal evolution of the cell-nanoneedle interface by novel electron microscopy methods combined with optical microscopy. It constitutes a groundwork study in the development of a fundamental understanding of the nanoneedle biointerface, which is necessary to engineer nanoneedle systems for cell manipulation in vitro and in vivo.

Sanchez, M. Stevens, Gold–silica quantum rattles for multimodal imaging and therapy, Proc. Natl. Acad. Sci. USA, 112,1959-1964 (2015).
    Summary: This work presents the first synthesis of Au@Si rattle-like particle with Au nanoparticles and nanoclusters growth in-situ and demonstrates the first therapeutic and diagnostic use of Au nanoclusters. For the first time it presents a biomedical application of paramagnetic Au. This study solves a longstanding challenge in the fabrication of silica encapsulated gold nanostructures and illustrates a simple synthetic pathway for nanoparticles where multimodal imaging and therapeutic functionality is an inherent property of the resulting particle, without requiring multicomponent assembly and concurrent surface functionalizations.

    Summary: Metal assisted chemical etch is a recently discovered strategy for anisotropic etch of silicon and other semiconductors. Its low cost, ease of use and reliability are rapidly transforming the fabrication of semiconducting nanowires for energy storage, photovoltaics and bioengineering. This work is the first systematic study of metal assisted chemical etch and provides guidelines for the rational design of silicon nanowires that have been followed by several groups internationally. The composition of matter developed in this work is the subject of an international patent. The techniques and the understanding developed from this study enabled nanoneedles fabrication.

    Summary: 75 First development of synthetic nanoparticle with leukocyte-like function. Porous silicon particles coated with leukocyte-derived membrane display enhanced circulation time with targeting and transendothelial migration characteristic of the original leukocyte. This feature is exploited to target drug delivery to cancer cells across a model epithelial layer in vitro. This work opens the stage to the development of hybrid bionic systems for therapeutic applications.
