Scientists have developed a novel strategy for improving the lateral resolution of optical microscopy by fabricating high-quality micro-spheres using laser-based 3D printing. This development offers a cost-effective alternative to expensive microscopy solutions, potentially revolutionizing the field with custom-designed devices that enhance resolution for any optical microscope.

Researchers at Guangdong University of Technology and Pudong New District People’s Hospital have developed a microfluidic chip that uses light to detect foodborne pathogens quickly, affordably and effectively. Published in AIP Advances, this new method could dramatically improve how food safety is monitored.

A new 3D printing method, called blurred tomography, could significantly enhance the production of microlenses with commercial-level optical quality. This innovative technique enables the rapid and efficient fabrication of various optical devices, producing optically smooth surfaces and complex shapes.

Researchers from Harvard and Google have co-created the most detailed 3D reconstruction of human brain tissue to date. This tiny slice of the temporal cortex, merely the size of half a rice grain, reveals an astonishingly detailed map .

For the first time, scientists at The Hospital for Sick Children (Sick Kids) used advanced imaging technology at the Sick Kids Nanoscale Biomedical Imaging Facility to reveal the atomic structure of an enzyme that neurons use to communicate.

Scientists have innovated a sustainable method to create electrochemical sensors by laser printing on fallen tree leaves. This technique, which transforms leaf cellulose into functional graphite sensors through pyrolysis, has proven effective in detecting substances like dopamine and paracetamol.

In a feat aimed at understanding how cells move and creating new ways to shuttle drugs through the body, scientists at Johns Hopkins Medicine say they have built a minimal synthetic cell that follows an external chemical cue and demonstrates a governing principle of biology called “symmetry breaking.”

Researchers at Rice University have unlocked the potential to use 3D printing to make sustainable wood structures, offering a greener alternative to traditional manufacturing methods.

Stanford materials engineers have 3D printed tens of thousands of hard-to-manufacture nanoparticles long predicted to yield promising new materials that change form in an instant. This innovative approach, highlighted in Nature Communications, may revolutionize everything from solar panels to computer memory.

Toxic chemicals used to flame-proof plastic materials can be absorbed into the body through skin, via contact with microplastics, new research shows.
