|Researchers at the ARC Centre of Excellence for Nanoscale BioPhotonics in Australia have developed a new method of delivering chemotherapy drugs with ‘X-Ray-triggerable liposomes’.|The common use of VP, lipids, Dox and X-rays in tumour treatment suggests that using X-raytriggerable liposomes to deliver drugs should work effectively in the clinical context.
|Multimodal imaging is just one of several benefits of the new approach to ultrasound.
|The trial is set to decide whether 3D mammography can become the new industry standard.
|Despite misgivings from some corners of the industry, AI in medicine is set to steadily increase.
|A 3D-printed foot model (left) and its cross-section (right) clearly reveal the intricate internal architecture of the different bone types, as well as the surrounding soft tissue.
Steven Keating and Ahmed Hosny/Wyss Institute at Harvard University.|A 3D-printed multimaterial model of a calcified heart valve shows hard calcium deposits (white) with fine-scale gradients in mineral density that are impossible to fully capture using conventional biomedical 3D printing approaches.
James Weaver and Ahmed Hosny/Wyss Institute at Harvard University.|Three of the co-authors of the paper, left to right: Ahmed Hosny holding models of Steven Keating’s tumor, Steven Keating holding a model of his own skull, and James Weaver holding models of Keating’s MRI scan.
Wyss Institute at Harvard University.|High-throughput tissue filtering, a major feature of the approach developed by the authors of the study, can help quickly remove extraneous tissue to reveal the desired underlying structures (right) without sacrificing the resolution or intensity gradients present in the native imaging data (left and center).

|Gadolinium chelates have been used over 400 million times since the 1980s, but Rice University nanoscientists have now loaded iron inside nanoparticles to create superior MRI contrast agents.|Scientists at Rice’s Laboratory for Nanophotonics added iron chelates (blue) and fluorescent dye (red) to multilayered gold nanomatryoshkas to create particles that can be used for disease therapy and diagnostics. The ‘theranostic’ nanoparticles have a core of gold (left) that is covered by silica containing the diagnostic iron and dye, which is covered by an outer shell of gold. The particles are about 20 times smaller than a red blood cell, and by varying the thickness of the layers, LANP scientists can tune the nanomatryoshkas to convert light into cancer-killing heat.
|Dr Maria Daniela Angione has developed an electronic chip housed in a sensing platform, to be used as a DIY diagnostic tool.
|Despite huge advances in the study of the human microbiome in recent years, new studies have shown the effect of non-antibiotic drugs on gut bacteria to be far greater than expected.|Microbes that are resistant to non-antibiotics also tend to be resistant to antibiotics, raising the possibility that resistance to the latter might be gained without taking them.
Machine learning has long been touted as the next big thing for healthcare. With countless start-ups investing in that promise, applications are emerging across everything from diagnostics to
