The ability to detect and study single proteins in their native state without the use of fluorescent labels is crucial for understanding the behavior and function of proteins in their natural ...environment. The contemporary used technique of fluorescence labeling can alter the structure and function of proteins, making it difficult to obtain accurate information about their behavior in vivo. The natural UV autofluorescence of proteins is a potential solution (excitation 250-290 nm, emission 320-360 nm), but it remains a challenge due to the low quantum yield and absorption cross-section of the emitters in UV.
The study of individual proteins in their natural state without the use of fluorescent labels is vital for gaining a comprehensive understanding of their behavior and function in vivo. However, ...traditional fluorescence labeling methods can alter the structure and function of proteins, leading to inaccurate data. To overcome this limitation, our team has developed a revolutionary label-free detection platform for single proteins in the ultraviolet (UV) range. This platform utilizes the natural UV autofluorescence of proteins and relies on a new optical horn antenna design, which allows for unprecedented resolution and sensitivity. While the current technology is state-of-the-art, it still has limitations, such as a limited enhancement of photon count rate of 10-15 times higher than confocal 1, 2. To achieve even greater enhancement, we are exploring the use of rhodium cube gap antenna self-assembled using capillary-convective forces inside a rectangular zero-mode waveguide.

This paper presents a simulated design of millimeter wave square patch antenna 1×6 array on silicon and Roger RO4003 substrate for prominent multiple bands i.e. 58GHz-60GHz, 65GHz-68GHz, 72GHz-77GHz. ...Designed antenna can serve 5G cellular network as well as advance device-to-device (D2D) network which is special feature of 5G communication system to reduce end-to-end latency and to implement Mission Critical Push-To-Talk Communication (MCPTT) and Vehicle-to-Anything (V2X) Communication. Designed antenna has peakgain of 9 dB and very high efficiency. Return loss for given bands at their resonant frequencies are as low as -35dB and total bandwidth of 9.57 GHz. Silicon is used under feeding network to enhance the bandwidth and reduce the size of feeding network and low dielectric material under patch to reduce dielectric loss thus maintaining the efficiency. Symmetrical parallel feeding network is used to enhance gain. Inset fed with quarter wave transformers are used for feeding and matching, along with maintaining the conformity. A novel design is used to kill the spurious radiation due to feed network, thus shaping the radiation pattern for cellular application. Overall size of antenna is 6.7mm×30mm×1.2mm compatible with miniaturized devices and is printable.
